About Me

Software Engineer with nearly 3 years of experience building production Rails applications at scale.

I'm passionate about solving complex problems with clean and scalable code, with strong focus on developer experience, testing, and quality. Creator of command_deck, an open source Rails engine that improves developer experience through a quick actions panel for devs. I value teams that move fast without sacrificing quality, make decisions based on first principles, and build products with real impact.
