I build production AI systems: RAG pipelines, LLM agents, and ML models that ship inside real products, not notebooks. Recent work: a citation-grounded RAG assistant (Claude API + pgvector) for a real-estate intelligence platform, and an XGBoost revenue-management system pricing thousands of daily airline flights. WHAT I DELIVER → RAG systems on your data: ingestion, chunking, embeddings, vector search (pgvector), and schema-validated, citation-grounded answers enforced in code so the model can't invent sources → LLM integration & AI agents: Claude and OpenAI APIs, tool use / function calling, agentic workflows, MCP servers, evals and guardrails → ML that earns money: demand forecasting, dynamic pricing, and valuation models (XGBoost, scikit-learn), containerized and retrained on schedule with Docker/Kubernetes → The full product around the AI: FastAPI or .NET backends, Vue/React frontends, PostgreSQL/PostGIS, auth, tests, CI/CD RECENT PROJECTS → LotScope (solo build): vacant-land intelligence platform. Async FastAPI, PostgreSQL + PostGIS + pgvector, Redis workers, Vue 3/Quasar frontend. Its "Ask the Parcel" RAG assistant answers zoning and feasibility questions with citations enforced by schema validation. → Airline revenue management (Japan): XGBoost models forecasting bookings, load factor, and ADR across thousands of daily flights; Kubernetes-scheduled retraining; pricing recommendations built on competitor and event signals. → Fortescue Metals "Catalyst": led migration of an enterprise portfolio platform to Vue 3 + .NET 9 with Snowflake pipelines, earned-value and financial tracking (22-month engagement). → King County Stormwater Planner: geospatial analysis across 90,000+ roads; 60% faster data loads through an intelligent caching layer. WHY CLIENTS KEEP ME - 100% Job Success, Top Rated Plus, 1,300+ hours on Upwork - Full-stack engineer first: your AI feature arrives with a UI, tests, and deployment, not a demo script - Enterprise habits from mining (Fortescue), government (PennDOT, King County), healthcare (a clinical app used in hospital emergency departments), and Fortune 500 (Kraft Heinz) work - I build with AI as well as build AI: my development workflow runs on Claude Code with specialized review, testing, and security subagents, so I ship fast without cutting corners STACK Python (FastAPI, Django) · C#/.NET · Vue 3 & React · TypeScript · PostgreSQL/PostGIS · pgvector · Redis · Docker & Kubernetes · AWS & Azure · Claude API · OpenAI API · XGBoost / scikit-learn Tell me what you're trying to build (or what's broken). I usually reply within a few hours with a concrete approach.
