I’m building a compact registration system and need a skilled backend developer to complete the core infrastructure. The application must store registration data in a MySQL database, generate admit cards and registration slips in PDF format, and allow administrators to create manual entries that are saved just like online submissions. Key elements I want you to handle: • Database layer – design the schema and write the queries/ORM code to capture every registration field, plus logs for audit and troubleshooting. • Payment flow – integrate Razorpay so the user can pay, receive an on-screen confirmation, and trigger creation of the PDF registration slip only after a successful callback. • Admit card generation – automatically compile the stored...

I maintain several live databases that generate a steady stream of purely numerical records—transaction totals, sensor readings, and performance metrics. The raw pulls already sit in secure tables; what I need now is a sharp pair of eyes (and ideally a few smart scripts) to make sure every figure is trustworthy before it feeds our reporting pipeline. Your focus will be end-to-end validation rather than manual typing. You’ll connect to the databases remotely, run consistency checks, flag outliers, trace discrepancies back to source tables, and document any corrections you make. If you prefer working in SQL, Python (pandas), or even a robust Excel environment linked through ODBC, that is perfect; the key is delivering a clean, fully audited dataset that reconciles against the or...

My application suddenly stopped reaching its underlying database and any direct connection attempt times out or throws generic “unable to access database” errors. Credentials have not changed and the server process appears to be running, so I suspect something deeper—possibly configuration, permission conflicts, or corruption—but I need fresh eyes to pinpoint and resolve it quickly. You will start by investigating the connection path end-to-end, identify the exact obstacle, then apply the safest fix to restore full read/write access without data loss. Please document the steps you take and any changes you make so I can keep the system stable going forward. To jump in, let me know which diagnostic checks you would run first and any information you need from me (log...

I'm the founder of NILQuant, an independent record for NIL deals in college athletics. We're looking for a qualified, independent reviewer for a scoped technical review of our core verification engine before its first production release. Scope (summary; full scope attached): - Rebuild our PostgreSQL database from its migration files on your own machine and repeat our test suite and reproduction kit - Check append-only history, two-person release controls, fingerprinting (SHA-256), school-to-school data isolation and a scoped verification API - Test the hosted demo with six test accounts (no admin access) and try to break the controls - Confirm our outside timestamping and write-once storage settings - Written findings, one retest round and a signed scoped conclusion All data is...

I need someone to install and fully configure the latest stable release of MySQL on a Windows-based machine that will act only as a local development server. Your job starts with the clean installation itself—downloading the correct installer, choosing the right configuration options for a single-instance environment, and making sure the service starts automatically with Windows. Once the database engine is in place, please secure it by setting a strong root password, removing test databases, and enabling any recommended Windows firewall rules so it is not exposed beyond the host PC. I will also need one non-root user created with full privileges for development purposes, plus a short verification script or command-line check that confirms connections work from MySQL Workbench and ...

I am building a complete smart-mailbox platform and need you to take care of every software layer. The web side must be developed in Laravel (latest stable/LTS) and will handle user registration, secure login, mailbox pairing, a live dashboard that shows whether the lid is open or closed, and a simple settings area where each user can enable or disable mobile push alerts. A companion app written in Flutter will run on both Android and iOS. After signing in, the user should instantly see the current mailbox status, browse a short history of recent events (the system only keeps records for a configurable, limited period), and receive push notifications whenever the Tuya smart switch detects a new “open” event. The delivery person from the postal company will be able to read a...

I need my web application, which provides company-related information and is currently integrated with a Firebird database, to be restructured. The database is embedded within the site code and needs to be separated so I can host the main site externally. Key Requirements: - De-link Firebird database from the existing web application. - Ensure the web application remains functional and accessible after separation. - Provide documentation on the new setup for future reference. Ideal Skills and Experience: - Strong experience with Firebird databases. - Proficiency in web application development and restructuring. - Familiarity with documentation and providing post-project support.

I have two parallel needs and would like to tackle them in one cohesive engagement. First, I need a job-posting platform built from scratch. The core flow should let employers register, create and manage vacancies, and let candidates build searchable profiles, apply, and receive status updates. A clean, mobile-responsive interface, secure authentication, and an admin dashboard for moderation and analytics are all essential. Feel free to suggest the best tech stack; I’m open to anything from a classic LAMP setup to a modern React + Node or Laravel solution as long as it remains scalable and easy to maintain. Second, I have a catalogue of product images that require professional Photoshop retouching. Consistent backgrounds, balanced lighting, dust removal, and colour accuracy are k...

I have three distinct text-file datasets—customer information, financial records, and survey responses—that all need to be brought into a clean, analysis-ready format. The job is twofold: first, accurately key or import every record into a structured spreadsheet or database layout; second, perform a full hygiene pass to remove duplicates, correct any formatting inconsistencies, and fill in the missing fields I will flag for you. You will receive a folder of raw .txt files plus a short field dictionary that shows the expected column names, data types, and any reference lists you can use for validation. Once the data is in shape, return it as Excel workbooks (or CSV if you prefer) that match the field order in the template I’ll provide so I can import straight into our CRM...

I’m ready to commission a full-stack solution that turns our current paper-heavy student office into a streamlined digital campus. The first release must focus on student enrolment and records management and be robust enough to let us expand later into timetabling or forum modules if we choose. What the initial build must do • Transcripts & grade tracking – students and authorised staff should see up-to-the-minute results, GPA calculations, and printable official transcripts. • ID card generation – on-demand cards with photos, barcodes/QR and expiry dates, exportable to standard badge printers. Access control Both students and staff will log in to view or update the records appropriate to their role. Please include role-based permissions, single sign...

I am ready to commission a complete, web-based management suite for a multi-store shopping mall. The project must cover two distinct areas: 1. A mall-level administration panel that tracks tenants, leases, foot-traffic analytics, promotions, and finance. 2. A store-level back office where each retailer can handle day-to-day tasks such as product catalogues, inventory, staff rosters, and sales reporting. Every screen has already been drafted; page 3 of the attachment contains the reference mock-ups that must be followed pixel-for-pixel while remaining fully responsive for desktop and large-tablet browsers. Key scope elements • Build a single-page web application that communicates with a secure REST (or GraphQL) API. • Design and implement the database schema, access l...
