About

I build backend systems that are expected to just work—at scale, under pressure, and without surprises. Over the past 6.5+ years, I’ve worked across SaaS, e-commerce, and gaming, focusing on distributed systems, backend architecture, and end-to-end ownership of critical features. Today, I operate as a Senior Backend Engineer (Tech Lead), where I lead backend initiatives, review system designs, and work closely with product teams to turn ambiguous ideas into reliable systems. My work sits at the intersection of: Scalable backend systems & distributed architecture Event-driven systems on AWS Designing systems that are simple to extend, not just fast to build I care a lot about how systems evolve over time—not just how they work on day one. That usually means making pragmatic decisions, keeping things simple where possible, and building with clarity so other engineers can move faster. Outside of core engineering, I’ve also been exploring ways to improve developer productivity using AI-assisted workflows and automation. If you’re working on something interesting in backend or distributed systems, I’d love to connect.
