Full-stack development
MERN stack, Angular, REST APIs, scalable backends, frontend performance, JWT and Passport.js authentication, and secure coding practices.
Senior Software Engineer
Scalable systems, AI in production, and full-stack delivery.
Building
I design and build enterprise-grade applications—MERN and Angular frontends, Node and Python services, microservices on AWS, and AI-powered automation for documents, speech, and real-time workflows.
About
Technical leadership across architecture, performance, and secure delivery for real-world business problems.
I am a Senior Software Engineer with deep experience in full-stack development, microservices, AI integration, and cloud deployment. I lead technical direction, optimize large-scale systems, and ship automation-driven platforms—from insurance and academic workflows to integrations with WhatsApp, Facebook, Wix, and Shopify.
I combine strong engineering practice (JWT, SSDLC, API hardening) with applied AI: document parsing, classification, RAG, and fine-tuned models—including Mistral 7B and production-oriented LangChain applications.
