`whoami`

Full stack engineer, eight years of it. Currently co-founding Lego Verse Module, building AI-driven SaaS on AWS.

The line I care about most in a system design: where the model is allowed to make a decision, and where it is not. Almost everything I ship has the same skeleton. A deterministic core owns state, money and limits. A probabilistic layer around it proposes rather than executes. Then a test asserts that every declared limit is actually enforced, which is where most agentic systems quietly fail.

principle	in practice
⛓️ The LLM never executes	Models classify, draft and propose. A rules engine approves, sizes and commits. Tests enforce the boundary.
🏠 Local-first by default	Ollama, whisper.cpp, ComfyUI, Qdrant. If it can run on the host, it does. Cloud is a target, not a dependency.
🔪 Vertical slices	Ship a complete flow, not a layer. Every slice is demoable the day it lands.
📏 Measured, not claimed	Every headline number comes from a benchmark committed next to the code.
