I build the part of software that makes an idea actually work.
With 6+ years in software development, I specialize in backend development, API integration, system architecture, troubleshooting, and turning complex requirements into reliable solutions.
I work with Node.js, PHP, JavaScript, React, databases, REST APIs, and third-party integrations. Whether you need something built, connected, fixed, or improved, I focus on both how the system works and how users experience it.
Let’s build it properly.
