CTO and software architect with a strong background in distributed systems, data platforms, and reliability engineering. I’ve built and scaled infrastructure supporting millions of users, worked on core database and platform technologies, and led engineering teams in high-growth environments. My work is deeply influenced by open-source culture, SRE practices, and the belief that robust systems emerge from strong teams, clear processes, and architectures designed to operate reliably under real-world constraints.
