I build production AI systems
that actually ship.

Software Engineer with 6+ years of experience and 3+ years focused on production-ready LLM applications — RAG, GraphRAG, agentic workflows, and context engineering in regulated environments.

Currently building profunc — a diagnostic layer for software development. Open to freelance projects and the right full-time role.

  • Are Media Houses the New Data Ingestion Centers for AI?

Common Questions

FAQ

What kind of AI projects do you work on?

I specialize in production-ready LLM applications — RAG and GraphRAG pipelines, agentic AI systems, context engineering, and intelligent document processing. I've shipped these in regulated pharma environments with full audit-trail compliance, so I'm comfortable with both cutting-edge AI and enterprise-grade reliability.

Are you open to full-time roles?

Yes — I'm open to both freelance projects and the right full-time role, especially in AI/ML engineering, LLM infrastructure, or senior software engineering positions at product-driven companies. I'm particularly drawn to teams pushing the boundaries of agentic AI and developer tools.

How long does it take to build an MVP?

Typically 4–8 weeks for a lean MVP, depending on scope. I focus on rapid prototyping with clean architecture that scales. We'll define clear milestones during our initial discussion so expectations are aligned from day one.

What's your tech stack?

Python, TypeScript, Go, and modern AI frameworks (LangChain, LangGraph, OpenAI, Bedrock). For backend I work with FastAPI, PostgreSQL, Neo4j, and Redis. Frontend with Next.js and React. Infrastructure with AWS, Docker, and GitHub Actions.

Can you integrate AI into an existing product?

Absolutely. I've done this extensively — adding RAG-powered search, building intelligent document extraction, creating chatbot systems, and designing agentic workflows that plug into existing business processes. I'll work with your existing stack.

What if I'm non-technical?

I excel at translating complex AI trade-offs into clear decisions. At WhiteHat Engineering, I regularly communicated technical choices to non-technical pharma stakeholders. You'll always understand what's being built and why.
