I've spent 25+ years building custom production systems, over $500K worth and more than 20 of those in .NET, and these days I'm focused on AI. I build LLM and RAG pipelines, AI agents, and document-intelligence workflows in Python and .NET, usually for businesses whose operations are too unique for off-the-shelf software to fit. The messy, niche, one-off projects most people won't touch are the ones I enjoy most. I automate the manual work that's eating your time and only bring in AI where it genuinely adds value. Hire me when you need something actually built, not just wired together out of existing tools. When the requirements are one of a kind and the domain is a real tangle, I work out the architecture, learn whatever the problem needs, and ship a production system from scratch. That's a big part of why clients stick with me: one for 13 years, another for 4, and a lot of them started with a single project and just kept coming back. "I have yet to give him a hurdle he can't clear." — Scot Nichols, Automotive Diag (2-year client) WHY BUSINESSES CHOOSE ME I don't just build what's on the ticket. I want the actual problem first. Before I write any code I dig into how your business runs: does AI really help here, or would something simpler be more reliable? How will it scale? What will the ongoing model and compute costs look like? Good software, AI or not, has to fit how your business actually works, not whatever's trendy this quarter. I spot the issues you might not see yet — runaway LLM costs, latency under load, multi-user concurrency, awkward integrations — and head them off before they get expensive. I've also helped clients set subscription pricing and cut cloud bills. And I build to last: Clean Architecture, real test coverage, monitoring, and documentation. WHAT SETS ME APART I work across the whole AI and software stack and more than one ecosystem: • AI & LLM engineering — OpenAI, Azure OpenAI, Anthropic/Claude APIs, RAG pipelines (vector + BM25 hybrid, reranking), pgvector, prompt engineering, model selection and benchmarking • AI agents & automation — Microsoft Foundry (Agent Service, Agent Framework), multi-agent orchestration, custom tools via Azure Functions / OpenAPI / Logic Apps / MCP, knowledge-grounded agents over SharePoint / OneLake / Blob, human-in-the-loop approval gates, A2A federation — published into Microsoft Teams and 365 Copilot • Document intelligence — Azure Document Intelligence (prebuilt + custom neural/template models for invoices, receipts, IDs, contracts), Azure AI Search knowledge mining, confidence-scored extraction with human-review routing, PII detection/redaction • Enterprise .NET — ASP.NET Core, Entity Framework, WPF, Clean Architecture • Python data engineering — FastAPI, pandas, Apache Airflow, async processing • Multi-cloud & real-time — Azure, GCP, AWS with Terraform; file monitoring, API integrations, automated workflows When I do use AI, I back it with real numbers, not guesswork — recall@k, MRR, and LLM-as-judge scoring for faithfulness and relevance. For agents that means real guardrails: per-agent identity and RBAC (Microsoft Entra ID), least-privilege tool access, prompt-injection mitigation, approval gates on anything business-critical, and monitoring of citation rates, retrieval accuracy, and token cost. If a plain, non-AI solution is more reliable or cheaper, I'll tell you up front. PORTFOLIO HIGHLIGHTS RAG Pipeline (Security Compliance) — End-to-end RAG over NIST security publications (SP 800-53 Rev 5 + AI RMF). Hybrid retrieval (vector + BM25) with a cross-encoder reranker, measured on a hand-labeled 95-question eval set: recall@5 0.63 → 0.83, MRR 0.48 → 0.64, holding at 10,000-chunk scale. Inline citations, grounded "I don't know", prompt-injection guardrails. Tech: Python, FastAPI, Azure Container Apps, Azure OpenAI, pgvector, Langfuse, CI/CD Automotive Documentation Platform — Multi-tenant system that automated a fully manual Google Sheets process. Syncs PDFs/images from field devices, organizes jobs, generates branded reports, and reconciles with QuickBooks invoices, eliminating missed billing. Built as a multi-tenant Azure SaaS. Tech: ASP.NET Core, Azure, QuickBooks API, OCR / PDF extraction Climate Data Integration Pipeline — One-off platform integrating 120+ government data sources, with scheduling, error handling, and monitoring. No template ETL tool could handle the source variation. Tech: Python, GCP, Apache Airflow, PostGIS Real-Time File Monitoring System — Event-driven Azure platform processing 100,000+ files. Self-healing recovery, parallel processing, sub-second latency.
