I’m a full-stack engineer who enjoys building systems end-to-end—from clean, intuitive frontends to scalable backend and cloud infrastructure. Over the past 10+ years, I’ve worked across fintech and high-traffic platforms, focusing on performance, reliability, and real-world impact. What makes me different is that I don’t just ship features—I think in systems, optimize bottlenecks, and bring AI into products where it actually adds value. Right now, I’m looking for a role where I can work on modern cloud-native or AI-driven products, ideally in a fast-moving team where I can take ownership, solve meaningful problems, and continue pushing into areas like distributed systems and intelligent automation.
