I'm a software engineer who thrives at the intersection of design and engineering, turning ideas into reliable, user-friendly solutions.

With a foundation in computer engineering and a track record of major performance-analysis projects, I bring a data-driven mindset to every project.

I build applications that run smoothly on all platforms and I enjoy creating personal projects that solve problems for people. My focus on clean architecture, automated pipelines, and thoughtful user experience keeps the work both scalable and accessible.
