I'm a backend/platform engineer and developer advocate with over 10 years of experience across startups and scale-ups, including Uber and DoorDash. At Uber, I’m a Developer Advocate for Cadence, the open-source workflow orchestration engine powering over 12 billion workflows per month. I work across teams to support adoption, resolve production issues, and scale distributed systems. At DoorDash, I was part of the Drive Merchant Services team, where I contributed to the migration from Django to Kotlin microservices by rewriting key customer support endpoints. I also designed and implemented a modular refund rules engine for our largest Drive partners, supporting flexible refund policies and internal operations tooling. I'm looking for an engineering-focused role where I can return to hands-on systems work, ideally with a strong technical team and a path toward engineering leadership (EM or CTO). I'm particularly interested in infrastructure, developer platforms, and systems in healthcare, logistics, finance, or defense. Outside of work, I enjoy sailing my 36’ boat around Puget Sound, riding my motorcycle, and diving deep into trivia across a range of interests. Let’s build something meaningful.
