01 / About

Engineering for reliability at scale

I’m a Software Engineer at KBTG, working on backend and cloud-native systems for banking. I like owning services end-to-end — from design through production — and I care most about what happens after launch: reliability, observability, and code that stays easy to change. AI-assisted development is part of my daily workflow, and I enjoy building small internal tools that make the whole team faster. I optimize for measurable outcomes over busywork, so what I build stays modern and dependable.
