About

I turn ideas into polished, maintainable software that feels ready for real users.

I have 3+ years of hands-on experience delivering public and private web applications across SaaS, travel platforms, e-commerce, inventory systems, and location-based marketplaces.

I work across frontend, backend, databases, deployment, API integrations, and automation. My focus is not only making pages look good, but making the whole product fast, clear, responsive, and easy to extend.
