What I'm looking for

I'm looking to build AI-driven SaaS products, LLM applications, RAG workflows, scalable APIs, and automation platforms where I can improve performance, reliability, and development speed.

I'm building AI-powered SaaS platforms at Imaginovation, combining React, Next.js, Node.js, Python, FastAPI, PostgreSQL, Redis, and AWS.

I deliver LLM-powered features, RAG pipelines, semantic search, document processing, vector search, and AI agent workflows using OpenAI, Anthropic, LangChain, and LangGraph. My work supports contextual AI responses across large document collections and 50K+ daily API requests.

Previously at Bellwood, I developed high-traffic SaaS and enterprise platforms supporting 25K+ users and backend APIs handling 2M+ monthly requests. I improved load times by 30%, reduced database response times by 35%, and built reusable frontend architecture that accelerated feature delivery.

Across SaaS, FinTech, healthcare, e-commerce, and logistics, I've built web applications, business workflows, integrations, APIs, and responsive interfaces from implementation through production support.
