I'm a Senior Software Engineer with 10+ years of experience designing and building scalable systems across DevOps, e-commerce, health tech, and public safety. I enjoy owning problems end-to-end — from architecture and backend services to clean, performant frontends. I'm passionate about writing maintainable code, applying best practices, and contributing to meaningful products.
