IT PM + AI/ML Engineer

The interface between human intent and machine intelligence

I build the systems where human judgment meets artificial cognition — practical LLM architectures that know their own limits.

For Decision Makers

The signal beneath the noise — value, impact, and what it means for your next move. Two minutes.

For Those Who Look Deeper

Descend into the architecture — constraints, tradeoffs, and the implementation patterns where novelty crystallizes into working systems.
