Who Am Iâ€”

I'm Santosh Singh Subba, known online as OM or HeloBABA. I'm a professional full-stack developer and software engineer with over 6 years of hands-on experience building production-grade applications across mobile, web, backend, AI, and infrastructure domains.

Neon Tunnel VPN is my flagship project â€” a testament to what one dedicated developer can build over time with the right vision, skills, and commitment. From a simple admin panel concept, I evolved it into a complete VPN business ecosystem spanning 16 development phases, 122+ documented features, and serving entrepreneurs across multiple countries.

My philosophy: build real things that solve real problems. I don't just write code â€” I architect systems, design user experiences, integrate payment pipelines, and deploy production infrastructure. Every feature in Neon Tunnel VPN has been designed, coded, tested, and deployed by me personally.
