About Me Welcome to my portfolio, where you can discover more about my programming and technology skills, along with what I do and who I am

Get to know me!

I’m a Software Engineer at GEICO, focused on modernizing commercial billing platforms. Recently, I overhauled a core API, reducing latency by 99% and removing 40+ redundant database queries per request to improve performance and reduce operational cost.

I write production code in Go, and also work closely with C#, Temporal, and Titan. Most of my day-to-day work is about making systems faster, cheaper to run, and more reliable at enterprise scale.

I hold a Master’s in CS from NYU. Feel free to explore my work, ask my AI Assistant anything to learn more about me, or just reach out.
