Senior Full Stack Developer and Software Engineer with 4+ years of experience building scalable web and mobile applications using React.js, Node.js, React Native, and cloud deployment tools. I handle the full lifecycle — analysis, design, build, test, deploy — with a growing focus on AI integrations: chat-bots, agentic tool calling, and RAG-powered widgets.
Recent work spans enterprise systems, government platforms, and medical data processing — including a fleet-management platform for New Jersey school bus operations (300+ vehicles, 18K+ students) and an AI-powered video generation platform with dynamic model selection.
"At the end of the day, it's not about the stack — it's about delivering value."
I design microservices with Node.js and Docker, ship on AWS (Lightsail, EC2, Elastic Beanstalk, ECS, Lambda) and DigitalOcean with Blue/Green deployments, and build real-time systems on Socket.io and WebRTC for products handling 1K+ concurrent users.
Specialized in RAG pipelines, vector search (Qdrant), and agentic tool calling — integrating LLMs (OpenAI, Groq) and voice AI (Cartesia) into multi-tenant platforms with per-tenant document isolation and RBAC/JWT-secured super-admin → admin → widget architectures.
