About me

Hi there! I'm Cyrus, a software engineer

from London, UK. Ever since I wrote my first

program, I've loved coding; it's a fun puzzle where the solution has real-world impact.

I'm particularly passionate about type safety and the

TypeScript ecosystem. I love exploring how these tools can help us build more reliable and maintainable software.

To me, coding isn't just about finishing a feature, but building the infrastructure for many features to come.

My favorite class at university was Computer Security.

Since then, I've been fascinated by the evolving landscape of cybersecurity, keeping up with newly

discovered vulnerabilities and staying current on modern security standards.
