Software Architecture & Domain Knowledge See projects

I've worked on fulfillment and logistics systems and e-commerce coupon platforms, building event-driven, serverless and microservice architectures at high scale. I also ship production AI agents and LLM tooling. I aim for systems that are simple to reason about, resilient when things fail, and easy to observe in production.
