Fullstack developer with 3+ years building secure, scalable web platforms end to end—React and Angular frontends, Node.js and Python backends, REST APIs, and real-time features using WebSockets/SSE. I own projects from architecture through deployment, monitoring, and support. I focus on secure APIs and access control (JWT/OAuth, RBAC, rate limiting), reliable integrations, and production-grade operations on Docker/AWS. I work independently, ship consistently, and maintain quality through automated testing and good engineering practices.…Fullstack developer with 3+ years building secure, scalable web platforms end to end—React and Angular frontends, Node.js and Python backends, REST APIs, and real-time features using WebSockets/SSE.

Fullstack Developer at Kidumedia

May 1, 2025 - Present

Sole engineer for a production field operations platform, owning architecture through deployment. Built a React 19 dashboard (Redux Toolkit, RTK Query, MUI) with multiple feature modules and role-based access control, plus operational views across jobs/technicians/inventory for three warehouse levels. Implemented real-time delivery using Socket.IO with JWT handshake and per-user rooms for in-app and notification channels (email/SMS). Integrated an external enterprise system via REST bidirectionally using idempotency keys, retry with exponential backoff, conflict resolution, and an audit trail; webhook endpoints were guarded by constant-time token verification. Hardened and operated the platform with CSP/HSTS/rate limiting, graceful shutdown, idempotent migrations, and observability using Prometheus, Grafana, and Loki. Maintained quality with ~1,100 backend unit tests and additional web/mobile/e2e suites.
