What I'm looking for

I want to build full-stack products using Node.js, React/Angular, and microservices—owning secure JWT/RBAC APIs, real-time features, and performance tuning with Redis caching. I thrive in DevSecOps cultures focused on OWASP-aligned delivery and measurable speed improvements.

I’m a results-driven Full Stack / MERN / MEAN / Node.js developer with 3+ years of production experience. I build secure, scalable systems with a performance-first mindset and a security-first DevSecOps approach.

I reduced API response times by 30% and MongoDB query load by 50% using Redis caching, and I’ve delivered 10+ production modules across government, SaaS, and enterprise clients. I design RESTful backends that hit sub-200ms targets under peak load while maintaining clean, production-grade architecture.

I specialize in multi-role RBAC with JWT auth, building isolated dashboards for customer, restaurant admin, and delivery partner use cases. For real-time experiences, I integrate Socket.io for live updates and use Google Maps API for route tracking and ETA.

Beyond building features, I architect 12+ production-grade RESTful APIs across multiple projects, engineer secure coding aligned to OWASP, and mentor junior developers on Node.js best practices. I also develop portfolio-ready projects using Angular 18+, React, MongoDB, Redis, and encryption where needed.
