What I'm looking for

I seek hands-on roles building production AI systems and scalable full-stack products where I can lead technical design, drive measurable impact, and collaborate with cross-functional teams in a growth-focused environment.

I am a senior AI and full-stack engineer with five years building scalable web and backend systems and three years leading AI/ML initiatives in NLP, semantic search, AI agents, and RAG architectures.

At Stripe I designed and deployed real-time RAG pipelines using LangChain and Pinecone, built conversational chatbots with Claude-3.5 and GPT, and created modular FastAPI backends to manage onboarding logic and chat context persistence.

I deliver production-grade frontends and UIs with Next.js, React, Tailwind CSS, and micro-frontends while improving deployment consistency through GitLab CI/CD, Docker, and automated quality checks.

I focus on measurable business impact: reducing API costs with caching strategies, optimizing workflows with Redis and AWS Glue, and improving time-to-market and client satisfaction through pragmatic engineering and data-driven decisions.
