About Me

I’m a full-stack software engineer with 10+ years of experience building production web applications, data-driven platforms, and internal tools.
I’ve worked across the stack with Ruby on Rails, React, Python/Flask, SQL, MySQL, and AWS.
I enjoy solving real-world engineering problems — from building new product features and APIs to developing data pipelines, improving existing systems, and tracking down difficult production issues.
I’m persistent, detail-oriented, and always interested in learning better ways to build reliable and maintainable software.
Most recently, I spent several years building and scaling advertising technology platforms at Infillion.
I’m currently exploring new opportunities in full-stack and backend software engineering.
