About

Backend engineer with 5+ years of experience contributing to mission-critical, complex production systems. I care about clean architecture, system design, developer tools, and reliable architecture, and I also know my way around frontend, mobile, and DevOps.

I build privacy-focused applications with a focus on user ownership of data. I keep learning, use AI tools to move faster, and share what I learn. I have solved 1,000+ coding problems and taken part in contests on online judges.
