Summary

With a robust foundation in full-stack development, I specialize in engineering mobile and web applications. I've held diverse roles, including software architect, lead developer, and team lead, consistently guiding projects from concept to completion. My core expertise lies in JavaScript and its modern ecosystems, encompassing extensive experience with React, Angular, Vue, and Svelte.

As a dedicated Linux user, I thrive in open-source environments, leveraging Unix-based systems for efficient development. My passion for React and modern JavaScript drives frontend innovation, while my backend experience ensures I design and implement efficient, high-performance systems.

Things I Like

I am interested in JavaScript projects on the server and client-side. I prefer to develop on Linux machines, and I appreciate it when I can bring/choose my own hardware. I'm very interested in automotive, aerospace, and clean energy spaces. I am no stranger to remote work. It's not for everyone, but it is for me. I have heavily invested in my home office. I also lease office space as an alternative location.
