Selected Work

How I Approach Engineering
Architecture
Complex systems should remain understandable enough for teams to change them safely.
Responsibility
AI speeds up edits. What lands in the system is the engineer's call.
Change
A system needs to change regularly without losing control of it.
Writing
AI Engineering
Notes on MCP, agents, context engineering, RAG, vector search and integrating AI into real software systems.
Software Engineering
