Senior Software Engineer | Designing Systems

Professional Summary#

Senior Software Engineer with over 6 years of end-to-end engineering experience, evolving from frontend development and co-founding a tech startup to leading backend architecture and most recently working in the cybersecurity space leveraging knowledge from both.

My career spans building dynamic React/Node.js applications, managing AWS cloud infrastructure, and now designing complex distributed systems in Go and TypeScript for global bot mitigation.

I am passionate about low-level programming, server optimization, and solving hard technical problems across the stack, from diving into browser API minutia to pulling memory profiles to debug container performance.
