About me
I'm a full stack developer with 6+ years of experience building real-world applications: ERPs, CRMs, e-commerce platforms, and third-party API integrations. My main stack is React, Next.js, and Node.js
If you have an idea or a business that needs a digital presence or a custom tool, I can take it from concept to reality. No middlemen, no surprises—just clean code that you or your team can maintain afterward.
