I'm a software engineer who focuses on developer productivity. I help teams deliver more by building the tools and systems that remove friction from their workflows, such as a web-based utility I created for developers to instantly compare JSON objects. My background includes full-stack development, AWS infrastructure, and leading projects from concept to production. I've established engineering standards, mentored teams, and implemented practices like trunk-based development. The goal is to make it easier for developers to ship great products. I see myself as a force multiplier: when developer experience improves, the whole team moves faster.…I'm a software engineer who focuses on developer productivity.
