About

I'm a senior software engineer, freelancer, and founder. I build products, SaaS platforms, and modern web applications for clients and for my own ventures, taking ideas from concept to launch with clean engineering and strong product thinking.
I care about building software that is useful, reliable, and ready to grow. Whether it’s an MVP, an internal tool, or a full SaaS product, I focus on practical execution, thoughtful interfaces, and systems that solve real problems.
