Project Title: Full-Stack Developer needed for Sports Management Platform Backend (PostgreSQL/Prisma) Project Description: I have a fully designed and responsive frontend for a sports performance management platform (CPM HUB) built with (App Router), React, Tailwind CSS, and shadcn/ui. The interface is ready, but the platform currently lacks a backend. I need an experienced Full-Stack Developer to build the database, implement authentication, and connect the frontend to make the application fully functional. Key Responsibilities: Database Architecture: Design and deploy a PostgreSQL database and manage it using Prisma ORM. Authentication & RBAC: Implement a highly secure Authentication and Role-Based Access Control system for 4 distinct user levels: Admin, Coach

I maintain several large, structured datasets spread across MySQL, PostgreSQL and SQL Server instances. Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships. Once the landscape is clear I need all records extracted, cleaned, normalised and deduplicated, then merged into a single, well-organised MongoDB database. Your work should include a carefully planned document model that supports growth, fast look-ups and straightforward analytics. Proper indexing, sharding strategy (where appropriate) and query optimisation are critical because future workloads will be heavy and latency-sensitive. Please deliver: • An optimised MongoDB schema and architectu...

My priority is reliability and data security rather than being tied to any particular framework. I’m aiming to move quickly, so please outline your development timeline, key milestones, and any past work that shows you have built comparable document-collect...

...authentication layer. The stack is TypeScript end-to-end, PostgreSQL for storage, and a React front-end that will consume your work through a clean RESTful API. Everything lives on a Linux server, so familiarity with its ecosystem is essential. Your main mission is to design and implement a rock-solid user authentication system—think sign-up, login, refresh tokens, password resets—while keeping performance tight and code readable. Alongside the coding, I need you to lock the server down: enforce SSL, fine-tune PostgreSQL roles, manage environment secrets, set up firewalls, and apply best-practice hardening so that security audits pass without a hitch. Deliverables: • Fully documented REST endpoints for all auth flows • PostgreSQL schema/mig...
