I'm a Senior Software Engineer with 6+ years of production experience across FinTech, Web3, SaaS, mobile, and cloud-scale systems — currently shipping at Must (South Korea, remote). I've led architecture migrations, owned end-to-end product launches, and built apps used across 5 countries.
I move fast on ideas, slowly on assumptions, and obsessively on performance & security.
