I'm a full-stack engineer and engineering lead with 6+ years building and scaling production e-commerce and AI systems. I specialize in shipping GenAI features that actually run in production, not just demos. What I deliver: - GenAI / LLM apps: RAG pipelines, AI chatbots and agents, intent classification + tool-calling, vector search. Stack: Python, FastAPI, LangChain, LlamaIndex, Claude/OpenAI, MCP, vector DBs, AWS Bedrock. - Full-stack web: React, Next.js (SSR/SSG/ISR), TypeScript on the front; Node.js, NestJS, FastAPI, GraphQL and REST on the back. - AWS and DevOps: ECS, Lambda, RDS, Redshift, Docker, CI/CD, and cost optimization. Recent results: - Built an AI support chatbot handling 5,000+ daily queries that cut support tickets 70%. - Migrated a storefront to Next.js, lifting Core Web Vitals from 15 to 80+ (5x). - Cut search costs 87% (Algolia to Typesense) and cloud egress 80% (S3 to Cloudflare R2). I currently lead a team of 6 at India's largest dental e-commerce platform, where I've proven these systems at real, high-traffic scale. The same patterns apply to SaaS, fintech, marketplaces and healthtech. I communicate clearly, scope tightly, and own delivery end-to-end. If you need a GenAI feature or a full-stack product taken from idea to production, let's talk.
