I’m an AI/ML Systems Architect who leads. I’ve spent 10+ years in AI/ML, from research to production systems. I started with neural nets for robotics, published papers, and earned two Master’s degrees. I love ML – problem framing, data strategy, training, and quality iteration – but I learned that at scale, AI is not just “a better model”, it’s systems architecture. The model is the engine, but the architect builds the car. As Head of AI at STXT, I led a team building a GenAI companion platform (chat, images, voice) – LLM + image-gen serving infrastructure to run under real load. Before that, at Toptal, I architected AI/ML platforms and data science work that accelerated teams moving from prototypes to production. Earlier at Arkadium Games, I stood up the AI department from scratch as Director of AI/ML, and as Director of Engineering, shipped games used by millions, where “can’t break” is the bar. I stay hands-on while building AI-native engineering teams, agentic workflows, and reliable production systems. I completed CTO School to sharpen strategic technical leadership, and I still attend NeurIPS and ICML to stay close to research – my way to see what will land in production 1–2 years out. Currently, I help teams build AI systems (e.g., multi-agent distributed systems) and train non-trivial ML (e.g., Bayesian and Reinforcement Learning LLMs).
