About

I’m a backend engineer who spends most of my time dealing with the infrastructure behind AI platforms. My sweet spot is distributed systems, strict security compliance, and user facing frontend work. In past roles, I realized that building a cool AI model doesn't mean much if it breaks data privacy rules or is too frustrating for internal teams to use. Because of that, I don't just hide in the backend writing Python and setting up AWS pipelines. I regularly jump into the frontend to build the actual tooling and dashboards needed to make complex architectures functional and secure. I like moving systems past the "experimental" phase into prod software that legal, product, and engineering teams can all trust.
