REST API & Backend Development (Node.js / Python)Alicia Kimani
I design and ship scalable, secure REST APIs — fully documented, tested, and ready for production. Not starter templates. Real backends with auth, validation, error handling, and database integration built in from day one.
My proof: A full ride-hailing backend (Uber clone) with 14 endpoints across 4 route groups, JWT auth, real-time Socket.IO location tracking, and Maps API integration. Deployed and verified end-to-end with Postman and Newman CLI.
What I deliver:
→ REST API design with clean route architecture (Express.js or FastAPI)
→ JWT + bcrypt authentication, token refresh, and role-based access control
→ MongoDB (Mongoose) or PostgreSQL (Prisma ORM) database integration
→ Input validation with express-validator or Zod — safe by default
→ Real-time features via Socket.IO where needed
→ Third-party API integrations (Maps, payments, auth providers)
→ Postman collection + full API documentation on delivery
→ CI/CD-ready — tested with Newman CLI in automated pipelines
I have 1.5+ years of professional backend experience in fintech environments, where reliability and security are non-negotiable.
