About

I love building software that scales and solves real problems. I build software in multiple languages, primarily Rust, JavaScript, and TypeScript, and try to make every system as efficient as possible. I have built multiple payment integrations for high-scale systems and event-driven systems using Kafka that process apporx more than 2 million events per day.
