> about.txt

Back-end engineer with 3 years of experience and deep blockchain/EVM expertise. I was part of a fast-paced startup journey that scaled from seed to Series A in 2 years, where I built high-throughput services in NestJS/TypeScript and Go, designed and operated PoS validator infrastructure, and built custom ENS resolver integrations.

I specialize in Golang, PostgreSQL, and modular system design—think clean architecture, DDD, and event-driven patterns. I adapt quickly to new stacks and domains, always focusing on building secure, stable, and observable distributed systems.

Beyond pure development, I have a big interest in collaborating on diverse projects outside the traditional tech space. I love applying my unique sense and developer approach to solve problems in unconventional domains—let's build something interesting together!
