About

I'm a Lead AI Engineer at Tesana, where I co-architected the agentic engine that turns a text prompt into a playable 3D game. The engine was demoed live at GDC 2026.

I build agentic systems end to end: fine-tuning and evaluating models, optimizing inference to run on our own hardware, and designing the harnesses agents act inside. I also built real-time multimodal agents that play games from screenshots alone.

I'm self-taught. I started coding in 2023 while running a restaurant kitchen and was leading AI engineering less than three years later. What pulls me forward now is understanding how these models actually work inside: mechanistic interpretability, alignment, and AI security.

Experience

Lead AI Engineer · Tesana

2026 – Now

Co-architected the agentic engine with the CTO, plus every system the AI touches. Fine-tuned an open-weight LLM for Godot game development: built and filtered the datasets, ran repeated SFT runs against custom benchmarks, and made its use of the Godot API far more reliable than the base model. Optimized KV cache and quantization to serve it on in-house hardware. Built real-time agents that play games from screenshots only. Engine featured in a live demo at GDC 2026; one user's single-prompt game drew 1.9M impressions and 7,000+ players.

Research

I build harnesses that push frontier models as far as they'll go, then measure what they can really do. This is capability elicitation: a model that fails with a weak setup can often succeed with the right tools, scaffolding, and challenges, and good evaluations depend on finding that ceiling.

I run about 1,000 agents a month on hard, open-ended problems, with single runs lasting up to a day, and they keep doing things I didn't expect. I want to understand where those abilities come from, which is what draws me to evals, mechanistic interpretability, alignment, and AI security. Write-ups will land here as they're done.
