Lukáš Kováč

👋 About

I'm a senior software engineer with over 9 years of experience designing, building, and maintaining reliable production systems. I focus on APIs, integrations, backend services, and internal tooling. These days, I work mostly with the Rust stack, but I can adapt to your needs.

⚠️ Not interested in cryptocurrency, blockchain, Web3, or related projects.
