...next three months to hunt down the root causes and redesign the platform so it scales smoothly. You’ll collaborate directly with me and two in-house developers; we work on GitHub, communicate over Slack, and deploy through a basic CI pipeline that will probably need tightening as part of this project. Key objectives 1. Diagnose and eliminate the freeze: trace blocking operations, long-running Mongo queries, memory leaks, or event-loop starvation. 2. Re-architect for scale: propose and implement a more resilient design—whether that means service decomposition, queueing, load balancing, horizontal sharding, or smarter caching. 3. Harden the codebase: add automated tests, performance monitoring, logging, and graceful-degradation fallbacks. Acceptance criteria ...

...the data layer designed around a hybrid model—relational tables for structured, transactional data alongside a NoSQL store for high-volume or schemaless collections—so familiarity with both SQL (PostgreSQL or MySQL) and something like MongoDB, DynamoDB, or Firestore is essential. I already have product requirements mapped out; what I need from you is: • A scalable architecture diagram showing tenancy isolation, shared services, and CI/CD flow • Implementation of the core multi-tenant framework (user provisioning, tenant onboarding, permission engine, billing hooks) • Database schemas and migration scripts for the SQL side, plus collections and indexing strategy for the NoSQL side • Containerised deployment (Docker / Kubernetes or sim...

...project-style gallery or dashboard that showcases trading instruments in real time, and a Contact form so users can reach support without leaving the page. The front end has to be modern, fast and responsive—React, Vue, Svelte or a similar framework is fine as long as it renders smoothly on desktop and mobile browsers. For the back end, I lean toward Node.js/Express or Python/Django with a SQL or NoSQL database to store user profiles, order history and configuration data. Real-time market quotes should stream through WebSockets from a third-party API, and every sensitive request must pass through HTTPS with the usual encryption, rate-limiting and input validation in place.

...foundation across web, mobile and cloud. The server side will run on .NET (Core/Framework) and expose RESTful endpoints organised as micro-services. For the browser I’m happy with either Angular or React—pick whichever you are fastest with—and the companion mobile app will be written in React Native so we can share as much logic and styling as possible. The data layer can land on SQL Server, a NoSQL store or a mix of both; I’m open to your recommendation as long as the choice is justified and future-proof. Everything will be hosted on AWS or Azure, wired into a CI/CD pipeline (GitHub Actions or Azure DevOps are fine) so every commit ships automatically through test, staging and production. Clean code, SOLID principles, meaningful unit and integration test...

I’m ready to roll out Anthropic’s Claude across the company so it can shoulder two core responsibilities—data analysis and project management. To do that, the agent must read (and potentially write) directly against our in-house NoSQL database. Think Mongo-style collections rather than traditional SQL tables; all the information that drives our operations lives there, so smooth, secure connectivity is non-negotiable. Here’s what success looks like to me: • Claude can accept natural-language questions, translate them into NoSQL queries, and return clean, easy-to-read insights or visual summaries. • The same agent can create, modify, and track tasks in our existing project-tracking tool through an API/webhook, keeping teams updated au...

...clean UI/UX, and an AI layer that quietly automates routine user actions so the overall experience feels magical rather than mechanical. You may choose the tech stack you work fastest with—whether that’s Flutter, React Native, or a hybrid of React.js for the front end and Node.js or Python on the back—but the end result must be maintainable, secure, and ready to scale. A MongoDB (or equivalent NoSQL) datastore fits our real-time data flow well, and any existing APIs can be surfaced through well-documented REST or GraphQL endpoints. Key deliverables • MVP Android app with core automation feature live • AI/ML engine (Python or Node) trained and integrated • Secure backend, auth, and API layer • Basic admin console for metrics and conte...

I will then pull the repo and test locally. Current functionality is limited to pure coding scaffolding—no auth, dashboards, or data visualisation yet—so please focus on a clean backend setup first. React, Node, and Mongo experience is essential. Looking ahead, once this baseline is stable we will layer in OpenAI features, Razorpay/Cashfree payments, and a refreshed UI, so build with extensibility in mind. Deliverables 1. Running project (frontend + backend) demonstrated live 2. Brief setup notes or README tweaks if anything differs from the commands above 3. ...

I would like to have a white figure sitting on the couch, binge eating, feeling sloppy on black background. On the other side, a black figure (similar to images attached) should be enjoying life, doing some happy activities like jogging, gym or similar on white background.

Technical notes I’m comfortable with React Native or Flutter, but I’m open to another modern framework if it reduces build time and keeps the code maintainable. A lightweight back end such as Firebase, Supabase, or a simple REST API with a SQL/NoSQL datastore is fine as long as it scales and lets me export the data. Deliverables 1. Fully functional Android and iOS builds ready for TestFlight/Google Play internal testing. 2. Complete, well-commented source code and asset files. 3. A concise setup guide covering local build, deployment, and how to add new products or moderate reviews. If you’v...

I’m finalising a nutrition-focused mobile product and now need the server side that can truly “think” before it answers. The stack is Node.js with Express and MongoDB, and the core requirement is an LLM pipeline that relies on retrieval-augmented generation, never hallucination. Here is what I need you to engineer: • A RAG workflow that pulls only verified nutritional data from my Mongo collections and feeds it to the language model, with additive analysis treated as first-class information. Accurate ingredient analysis is the single most important metric for success, so the retrieval layer has to be rock solid and testable. • User context handling: every response must factor in stored health profiles— allergies, chronic conditions, dietary g...

To apply, send a detailed project proposal that demonstrates how you have architect...

I have a collection of raw datasets that need a well-structured data model before we can move on to deeper analytics and reporting. At this stage I’m still weighing up whether a traditional SQL engine, a NoSQL store, or a cloud-native solution will suit the project best, so I’d value your guidance on the trade-offs while we shape the schema. Your task is to examine the source data I provide, recommend the most appropriate modelling paradigm, then design and implement a clean, scalable structure. Strong familiarity with relational techniques (ER modelling, normalisation, indexing strategies) alongside experience with denormalised or document-oriented patterns would be ideal. If a cloud platform such as BigQuery, Redshift, or Azure SQL turns out to be the right fit, I&rsq...
