What I'm looking for

I seek a role building scalable backend systems with strong security practices, collaborative teams, mentorship, and opportunities to work on payments, real-time features, and performance optimization.

I am a back-end developer focused on building scalable, secure server-side applications using Node.js and Express.js, with hands-on experience in JWT authentication, Redis caching, real-time WebSocket features, and cloud media storage. I have delivered payment integrations, encryption mechanisms, and robust database solutions using MongoDB and PostgreSQL during internships and projects.

I prioritize clean, testable code, modular service design, and thorough API documentation (Swagger/Postman). I thrive on solving performance and security challenges, applying pagination/filtering patterns, role-based access control, and microservice concepts to produce production-ready systems.
