About Me

I’m a Full-Stack Developer with 3+ years of hands-on experience building scalable, high-performance, and production-grade web applications across modern frontend and backend ecosystems using React, Angular, TypeScript, Node.js, and Express.js. I specialize in architecting performant user interfaces, robust backend services, and maintainable full-stack systems.

My expertise includes designing and integrating RESTful APIs, architecting microservices-based backend systems, optimizing MongoDB data models and query performance, implementing real-time applications using WebSockets, and delivering Web Real-Time Communication (WebRTC) powered communication workflows.

I drive end-to-end feature delivery across the software development lifecycle, from requirement analysis, technical design, and component architecture to backend integration, unit testing, CI/CD automation, production deployment, and post-release optimization. I collaborate cross-functionally with product, design, QA, and engineering teams to deliver scalable, maintainable solutions.

I have extensive experience building CPaaS platforms, CRM systems, campaign management modules, analytics dashboards, and enterprise SaaS applications. My work includes architecting systems from scratch, integrating third-party APIs, handling high-throughput data flows, and continuously optimizing UX across desktop and mobile platforms.
