The highest-priority data points are followers, following, engagement rate, audience country, e-mail addresses, and city/state, followed by age, gender, fake-versus-real follower ratio, profile picture and post metadata. Engagement rate must follow the “likes + comments over a period of time” formula; please make the period configurable so I can test different windows later. The service should expose clear JSON endpoints, return clean, well-typed responses, and include concise setup instructions for deployment on a standard Node environment. Before final hand-off I need a simple document that flags any fields Instagram does not make...
I already have a working prototype hosted on Replit: The core screens and features on that link must stay exactly as they are; what I need now is the infrastructure and polish that turns it into a production-grade tool for my resort. Access & authentication • Staff will log in from both smartphones and laptop . • Login should rely on phone number + password for everyone, with one admin account holding full privileges. Cloud architecture The app has to run on a scalable cloud stack (AWS, Firebase, Supabase, or any comparable service) so that data is instantly synced across all devices, even on spotty resort Wi-Fi. I also need an admin dashboard in the cloud where I can oversee everything in real time. Data export From within the dashboard I must be able to export...

I’m ready to launch a full-scale online marketplace dedicated to physical goods and need a developer who can take the project from blank server to live storefront. Shoppers must be able to browse vendor pages, add items to a unified cart, and check out seamlessly with credit/debit cards, PayPal, or a direct bank transfer. Product pages have to feel trustworthy and engaging, so every listing needs space for several high-quality images, a star-based rating, and text reviews that appear only after verified purchases. A clean seller dashboard for inventory, order processing, and payout tracking is essential, while I need an admin panel that lets me approve vendors, resolve disputes, and feature select products. The build should be responsive for mobile and desktop, optimised for fast...
I have two separate websites already coded in React with a framework and I now need them up and running on AWS. The repositories are clean and ready to ship; what’s missing is a solid, production-grade deployment. Both projects should live on their own EC2 instances (or another AWS service you feel is more appropriate, I’m open to suggestions) and reach the public through their respective custom domains. Each site also requires an attached database—feel free to recommend the best fit, whether that’s RDS, DynamoDB, or another AWS-native option. To keep things crystal-clear, here’s what I need delivered: • Source pulled, built, and served from AWS • Databases provisioned and connected to each app • Custom domains configured and resolving o...

I need a full-stack partner to take my functional blueprint for a lightweight, scalable Market Insights web application and turn it into a production-ready product. The build is split into two tightly-coupled modules: 1. Admin Portal • Secure JWT login • CSV upload that captures the three mandatory metadata fields—Date range, Data source, and Geographical region—then stores both data and metadata in PostgreSQL or MongoDB • Creation, editing, and retirement of Market trends dashboards • Assignment and revocation of those dashboards to individual customer accounts 2. Customer Portal • Role-controlled access so each user sees only the dashboards assigned to them • Fast search and filters by domain, sub-domain, tags, s...
The job is to architect and code a clean Node.js/Express backend that focuses on data processing and exposes a set of robust APIs the UI can consume. Scope of work • Design MongoDB schemas with Mongoose, handling validation, indexing, and relationships. • Implement business logic layers so the server can ingest, transform, and serve data efficiently. • Build versioned API endpoints, add middleware for validation, error handling, logging, and rate limiting, and keep the codebase modular for easy scaling. • Document every route clearly (Swagger or an equivalent Postman collection) so front-end integration is friction-free. • Set up scripts and brief instructions for local development, environment variables, and one-click deployment to a cloud host (Heroku,...

I have an AdonisJS/Node.js backend paired with an Angular front-end that already handles core routing and views. The next milestone is to finish the production-ready features: • Authentication: replace my temporary email/password flow with a single-click Facebook social login. The token should be verified server-side and mapped to the existing user model, preserving session security and refresh logic. • Storage: wire up Amazon S3 as the definitive store for uploaded photos and videos. I need signed-URL uploads, public/private ACL handling, and clean folder naming that matches each user’s UID. • Subscriptions: the app lets one user subscribe to another. I have the schema; I now need the complete create / cancel / list endpoints plus the matching Angular services an...

I want to turn a set of functional specs into a production-ready web application focused on data analysis. The core of the product is threefold: interactive data visualisation so stakeholders can explore trends in real time, automated reporting that runs on a schedule and ships PDF/Excel outputs straight to their inboxes, and a predictive analytics layer that applies basic machine-learning models to forecast key metrics. The stack is flexible—React, Vue or another modern front-end coupled with a Node, Python or similar back-end will work as long as the final codebase is clean, documented and easy to extend. A relational database (PostgreSQL or MySQL) is preferred for storage, and the whole solution should deploy smoothly to a mainstream cloud provider. Deliverables • End-to-en...
I am migrating an app from Firebase Auth to Supabase Auth. However, FlutterFlow only supports one authentication provider at a time, so users cannot log in with their old Firebase passwords unless we manually verify them. Firebase password verification uses a special SCrypt hashing algorithm, and this can only be validated using the Firebase SDK, which requires Node.js. For this reason, I need a small secure API service that does the following: 1. A Small Secure Node.js API (1–2 endpoints) The API must: Accept email + password from the FlutterFlow app Verify the password using: Firebase SCrypt hashing Firebase Admin SDK If the password is correct: Automatically create/update the user in Supabase Auth Set a new Supabase password transparently Return a success response so t...
I have an e-commerce site running on the MERN stack (MongoDB, Express, React, Node). I now need Razorpay fully wired in so customers can complete checkout without leaving the site. Alongside the code-level work, I also need guidance setting up a fresh Razorpay business account—help me from initial signup through to production-ready API keys. Here is what I expect at the end: • Backend: Secure Node/Express endpoints that create Razorpay orders, verify payment signatures, and update my existing MongoDB order records. • Frontend: React components or hooks that trigger the payment popup and handle success / failure callbacks gracefully. • Account setup: Walk me through activating the account, KYC, and moving from test to live mode. • Testing & hand-off: Demon...

Each time I push my project from GitHub to DigitalOcean and hit redeploy, all of my PostgreSQL records vanish. The application itself comes back up but the database is completely empty, so I clearly haven’t configured persistence correctly. Here’s what you’ll walk me through in a live video call (no hands-on coding from your side, just guidance and screen-sharing while I do the typing): • Identify exactly how my Postgres instance is running in DigitalOcean (managed database, Docker container, or one-off service) and confirm whether a volume or external DB is needed. • Show me the correct way to attach or mount persistent storage so data survives every redeploy. • Help me migrate the current credentials out of the GitHub repository and into proper en...

My production-ready Node.js application is live, but a handful of planned modules are still sitting on the roadmap. I’m looking for a developer who can dive into the current codebase, understand the existing patterns quickly, and build out those missing features so we can move to the next release without delays. Scope • Add the remaining modules (details and priorities will be shared on kickoff). • Integrate each new piece seamlessly with the current REST/JSON endpoints and front-end hooks. • Write clean, well-commented code and brief setup notes so the rest of the team can follow your changes. • Push work through Git with concise, self-contained commits and create pull requests for review. • Provide a short hand-off walkthrough once everything is ...
I need an Angular specialist to complete a full customer-facing front end that moves cleanly from a public landing area into authenticated screens. The work includes integrating an existing API, implementing secure sign-in and sign-up and wizard, and delivering responsive authenticated pages with dashboards, settings and account management. The build must use idiomatic Angular with clean TypeScript, SCSS, routing, services and sensible state management. It must support token handling and future OAuth integration. Final delivery requires full source, build instructions and a working environment through npm install and ng serve.
I need a full-stack MERN web application that lets people publish and discover group-chat links. Users will be able to submit WhatsApp, Telegram, and Instagram group invitations, tag each post with one or more locations they select, add a short description, and then share it publicly on the site. Visitors should, in turn, filter the feed by location, view matching posts, and join the groups directly from the link section. Account creation must rely on phone number verification or email or social logins. A one-time code flow (Twilio or similar) is fine as long as it is secure and reusable for sign-ins. Key features I expect: • React front-end with a clean feed, submission form, map-style or dropdown location picker, and responsive design. • Node/Express API handling authenticati...

The React-based admin panel is already pixel-perfect; the Node.js + Express API (MongoDB) that powers our mobile app is live in production. I now need the interface to talk to the real server, not mock data. First, hook up JWT authentication: the login screen must hit the /auth endpoint, store the token, and guard all routes with React Router v6. An Axios instance with interceptors should inject the bearer token automatically and handle refresh or logout on 401. Next, replace every placeholder call with the proper endpoints for users, jobs, applications, credits, and coupons. Each action—blocking a user, deleting or approving a job, issuing or disabling a coupon—must trigger the correct POST / PUT / DELETE request and update the UI immediately. The dashboard cards and charts...
I’m ready to move from scattered spreadsheets to a focused, browser-based CRM and I need a full-stack developer who can take the idea from wireframe to production. The goal is a modern web application that lets my team manage customer relationships in one place: create and view accounts, track interactions, run quick searches, and see simple dashboards that summarise activity at a glance. The core should be built with a widely adopted front-end framework (React, Vue, or similar) paired with a robust back-end stack (Node/Express, Django, or another framework you’re comfortable scaling). A relational database such as PostgreSQL or MySQL is preferred, but I’m open to NoSQL if you can justify the fit. Clean, well-commented code in a private Git repository is essential so fut...
I’m building a web application and need an experienced full-stack developer who is physically based in Surat, Gujarat. The front end relies heavily on TailwindCSS, so you should be comfortable crafting clean, responsive interfaces without relying on heavy UI libraries. On the server side I’m looking for true full-stack versatility—you should be able to pick up and implement whichever language (Node.js, Python, or PHP) best suits each feature. Our data layer is MongoDB, so please come prepared with solid schema-design and aggregation experience. We’ll begin with a single feature module so I can review code quality, communication cadence, and turnaround time. Once that milestone is approved, we’ll move through the remaining features one by one. Deliverables: ...
I’m building a modern e-commerce platform and need a developer who can own both sides of the stack. The front end will be a React SPA; the back end will run on FastAPI with MongoDB as the primary data store. Core features that must be in place from the first release: • Secure user authentication (sign-up, login, session handling, password reset). • A searchable, filterable product catalog served from MongoDB. • A persistent shopping cart that survives page refresh and login events. • Payments through credit/debit cards as well as and UPI. • A “popular products” recommendation block on the home page and product detail pages, updated automatically from aggregated sales data. Tech expectations React (hooks, context or Redux—your choice)...
The core build of my React application is 90 % finished, but I still need an experienced full-stack hand to take it across the line into production. Your two key missions are: 1. Polish the UI • Tidy up the navigation menu so it feels smooth and intuitive. • Refine all forms and input fields for better validation, consistency, and mobile responsiveness. • Refresh visual elements—buttons, icons, micro-interactions—so the whole interface feels cohesive. 2. Tie the stack together • Wire every React component to the existing REST endpoints. • Confirm data flows cleanly in and out of the current MongoDB setup. • Prepare the codebase for a later shift onto AWS (Atlas, DocumentDB, or another managed service—open to yo...
I’m building out the data layer of an application and need a Node.js developer who is already based in Hyderabad so we can occasionally white-board together in person. The core focus is database management: designing schemas, optimising queries, writing migration scripts, and exposing well-structured models to the rest of the stack. There’s no rush on deadlines; I prefer solid, maintainable code over quick hacks, so you’ll have the freedom to think through architecture decisions and test thoroughly. You’ll handle everything behind the scenes—from setting up the connection pool and indexing strategy to implementing role-based access controls—while keeping future scalability in mind. If you’re comfortable pairing on-site when needed, confident with ...
I’m building a new lead-generation platform and need a clean, scalable backend that can ingest and store three distinct data streams for every prospect: their basic contact details, key demographic traits and any behavioural signals we pick up along the funnel. All information should live in a single MongoDB instance; please structure the collections so that future analytics queries remain fast even as volumes grow. A lightweight REST or GraphQL layer that exposes create, read and update endpoints is essential so the frontend team can plug straight in. I work mostly with Node.js and Python micro-services, so if you can keep to that ecosystem it will make hand-off easier, but I’m open to other stacks as long as they deploy smoothly to Docker/Kubernetes. Deliverables • M...
I’m expanding a distributed team that is building a brand-new online platform. Our main office is in Europe, while several developers in India are already tackling different modules. To keep momentum high I’d like to add one more full-time freelancer who can own an entire module end-to-end. How we work • You take full responsibility for a module: backend (Node), frontend (React), automated tests and concise documentation. • We agree on a time frame and a fixed price for the first module—e.g. the customer-register component recently cost €1 000. • After that, payment switches to an hourly model starting at €6 for roughly 170 h/month, with proven quality bumping the rate up to €8+ over time. • You’ll be collaborating daily w...
I’m building an online business directory from the ground up and need a developer who knows the Node.js ecosystem inside-out. The goal is a fast, scalable platform where companies can be added, searched, and browsed with ease. Here’s what I have in mind: • A clean Node.js + Express backend that handles all CRUD operations for business listings. • REST-based (or GraphQL if you prefer) endpoints so the front-end can be expanded later without rewrites. • A responsive database layer—MongoDB fits, but I’m open to your suggestion if you can justify it. • Basic admin tools to add, edit, and disable listings quickly. • Elastic search, text indexing, or any efficient search strategy that can surface results by name, category, or location i...
