What I'm looking for

I’m looking for product-focused teams where I can own meaningful problems end-to-end. I want to work closely with product and engineering teams to design systems that scale, make thoughtful trade-offs, and build clean solutions that last as the product evolves. I care about solving real problems for real users, not just writing code.

I build software that holds up for the product, the team, and the business.

For 10+ years, I’ve worked across the stack: backend services, APIs, frontend apps, cloud infrastructure, and system architecture. I like figuring out how things should be built, what trade-offs make sense, and how to keep systems maintainable as they scale.

Along the way, I’ve designed systems that scale, mentored other engineers, and worked closely with cross-functional teams to deliver clean solutions that are easy to maintain and evolve as products grow. Lately, I’ve also been increasingly interested in how AI powered systems create new challenges in scalability, data management, and product design.

I am mission-driven. I care about working on products that solve real world problems and have meaningful impact. That’s what keeps me focused on shipping solutions that are reliable, maintainable, and useful to the people who depend on them.
