About

I'm a software engineer passionate about helping startups build and scale. Over the years, I've worked across the full stack — from redesigning e-commerce storefronts to architecting cloud infrastructure that serves thousands of users.

My work spans fintech payment systems, trade finance dashboards, CRM platforms, and cloud-native applications. I'm driven by the challenge of simplifying complex problems and turning ideas into reliable, production-grade software.

Most recently, I've been exploring the intersection of AI and software development, training advanced AI models to write better code. I've also been diving into blockchain technologies—decentralized applications (DApps) and smart contracts.
