AI Application Development

From Prototype to Production in Days, Not Months. Production-ready RAG systems with measurable quality improvements.

Show more details expand_more

Portfolio

Live Production Demos:

  • Vercel RAG Demo — Full-stack chatbot with semantic search. Next.js 16, React 19, OpenAI GPT-4o, Neon PostgreSQL (pgvector). Sub-second streaming responses.
  • Cloudflare Workers RAG Demo — Edge-deployed RAG with on-device LLM inference (Llama-3.1-8B). Zero external API calls, optimized for global latency.

Research & Evaluation:

  • RAG Quality Evaluation Lab — Jupyter-based experimentation framework with custom metrics. Achieved +15% precision improvement through systematic testing.

Evidence:

  • ~5,000+ lines of production-quality Python and TypeScript
  • Two live, public demos with real user traffic
  • Custom evaluation framework with measurable improvements

What I Deliver

Production-Ready RAG Systems — Not tutorials. Production systems with sub-second latency, multi-LLM architectures (OpenAI, Anthropic, Llama), vector database design (pgvector, Cloudflare Vectorize, Pinecone), and advanced retrieval patterns (reranking, query expansion, hybrid search, semantic chunking).

Evaluation Rigor That Drives Improvement — Custom evaluation frameworks built from first principles with ground-truth dataset curation, retrieval metrics (Precision@K, Recall, MRR), generation metrics (relevance, hallucination detection), and ranking metrics (NDCG). Proven results: +15% precision, +22% overall quality.

Full-Stack Integration — React/Next.js frontends with streaming UX, edge deployment for global latency, authentication and rate limiting, cost optimization strategies, observability and monitoring, security considerations for user data and prompt injection.

Agentic Development Expertise — Evaluated 6+ agentic coding tools (Claude Code, Kiro, Copilot). Demonstrated 2-3x development velocity through tool mastery and context engineering patterns.

Why This Matters

I Ship — My RAG demos run in production with real users. I deploy to multiple platforms, implement authentication, handle errors gracefully, and optimize for cost.

I Measure — Ground-truth evaluation, not hunches. When I say "+15% precision improvement," I mean I curated test datasets, measured baseline performance, implemented changes, and validated results.

I Understand Infrastructure — 10+ years of observability and on-call for revenue-critical systems informs every architectural decision. I know what breaks at scale, what costs spiral, and what keeps you up at 3 AM.

I Move Fast — Prototype fast, iterate based on feedback, and ship incremental improvements without rewriting everything. "Thinnest Viable Platform" methodology leveraging agentic development tools for rapid deployment.
