I've used Claude Code, GitHub Copilot, and other AI tools every day for over a year. Here's what actually saves time, what wastes it, and the productivity trap nobody talks about.
I built a GitHub Action that uses Claude to review PRs. The first version was annoying. The current version catches real bugs. Here's the whole journey.
I experimented with CrewAI and LangGraph to build multi-agent workflows. Some were genuinely useful, some were expensive toys. Here's what I learned.
We built a RAG knowledge base. The first version gave wrong answers half the time. Six months of iteration later, it actually works. Here's every lesson.
We tested ChromaDB, Pinecone, Weaviate, Qdrant, and pgvector for our RAG system. Benchmarks, costs, developer experience — and the one I'd pick today.
We integrated Azure OpenAI into a client's enterprise platform. Here's the practical stuff — networking, content filtering, cost surprises, and what the docs don't cover.
I started with ASP.NET Web Forms in 2008. Now I'm building AI agents with .NET and Python. A reflection on how the ecosystem changed — and how it didn't.
The story of migrating a 2M+ line retail platform to microservices. What the strangler pattern actually looks like when you're in the middle of it.
