A high-performance REST API for team task management at scale.

TaskFlow API
The Problem
The client needed a reliable backend for a SaaS task management product handling thousands of concurrent users, with complex permission rules and real-time updates.
The Approach
I started by mapping the data model — projects, tasks, users, roles — then designed the API contract before writing a single line. Chose PostgreSQL for relational integrity and Node.js/Express for the runtime. Added JWT auth with role-based access control from day one.
The Solution
Built a fully documented REST API with 40+ endpoints, JWT authentication, role-based access control (admin, member, viewer), pagination, filtering, and full test coverage. Deployed with Docker for environment consistency.
