Over deze dienst

Need AI that does real work, not just chat? I build custom AI agents, RAG document search, and LLM integrations that plug into your product.


Senior engineer, 23+ years, with deep hands-on AI work: retrieval-augmented generation, multi-step agents, and LLM pipelines in production.


What I build:

- RAG search over your docs, PDFs, or database, with grounded, accurate answers

- Custom AI agents with tool use and function calling (research, triage, extraction, automation)

- LLM features inside your app: summarize, classify, extract, semantic search

- Integrations with OpenAI, Anthropic Claude, LangChain, and vector databases

- Deployed with a clean API or UI, source code included


You bring your own LLM API key, so you control costs. Tell me what you want the AI to DO and I'll scope it by outcome.


Tech: Python, Next.js, TypeScript, OpenAI, Claude, LangChain, vector DBs.

Senior software engineer with 23+ years building enterprise apps, REST APIs, and AI-powered solutions. I specialize in C#/.NET 8, ASP.NET Core, Go, and React/Next.js with TypeScript, plus secure API design and SQL Server optimization. I've built AI speech-to-text pipelines, real-time systems with SignalR, and full-text search platforms, and I ship modern full-stack apps with Stripe, PostgreSQL, and LLM integrations (Claude, OpenAI). Clean, scalable, secure code, on time and on budget. Let's build something great together.
