What I'm looking for

I'm looking to build and ship production AI and full-stack features in a fast-paced team, solving complex engineering problems through strong testing, documentation, and end-to-end ownership.

At Octopi Poker, I engineered and released an AI product feature across two repositories, spanning REST endpoints, Postgres tables, gRPC integrations, and two LLM providers.

I built a deterministic poker-hand grading engine against solver data and constrained LLMs to summarization through prompt versioning, sanitization, and banned-vocabulary controls. I also designed LangGraph chatbot workflows and an 80+ case Langfuse evaluation suite.

Previously, I trained neural networks on 1.1M+ game-theory decision nodes and helped build a web application for real-time model inference and out-of-sample evaluation. I enjoy fast-paced teams where I can ship reliable solutions to complex engineering problems.
