SCROLL TO EXPLORE

From real-time systems
to AI systems.

I started by building production games and real-time multiplayer systems. Today I'm focused on AI applications where retrieval, orchestration, evaluation and software engineering matter as much as the model itself.

AI-first projects, followed by systems built in production.

Models are only
one layer.

I care about the engineering around the model: retrieval quality, orchestration, APIs, caching, evaluation and reliable execution.
