Professional Journey

Senior Node.js Developer & Backend Engineer

I am a Senior Software Engineer with 6+ years of professional experience in software development, with a deep focus on Node.js and Express.js backend engineering. I specialize in designing and maintaining high-performance REST APIs, implementing secure authentication systems (JWT & RBAC), building webhook pipelines, and managing asynchronous background workers with Redis and Bull Queue.

As a complementary strength, I bring solid full-stack capabilities with the MERN and MEVN stacks (React.js, Next.js, Vue.js, Tailwind CSS). Having started my career with PHP (Laravel & CodeIgniter), I have strong architectural versatility in both modern JavaScript/TypeScript services and enterprise web platforms.

Throughout my career, I have single-handedly engineered and deployed a mission-critical wire transfer management platform running in production with zero critical bugs, built high-throughput MLM SaaS platforms with automated WooCommerce synchronization, developed AI-powered document search platforms with vector embeddings, and delivered secure government e-governance systems on schedule.
