What I'm looking for

I’m open to global relocation and remote opportunities.

At GoBots, I led a frontend architecture redesign that cut average build times by up to 75%. I also re-engineered a high-traffic WebSocket service, migrating it from Kotlin to Go to improve the scalability and reliability of real-time updates.

I build SaaS features with TypeScript, React, and Next.js, and backend services with Kotlin and Spring. My work has included e-commerce integrations, internal developer tooling in Go, and serverless workflows at Yao Technology; I’m also open to global relocation and remote opportunities.
