Hi, I’m Raju Gupta — a passionate full-stack developer and system architect specializing in automation, billing systems, and scalable web applications.
With years of hands-on experience in WHMCS development, VoIP integrations, server infrastructure, and mobile app development, I help businesses transform complex technical workflows into seamless automated systems.
What I Do
I specialize in:

I focus on building systems that are secure, scalable, and fully automated — reducing manual work and increasing business efficiency.
My Approach

Every project I work on follows three principles:

Whether it’s integrating payment gateways like Stripe or Razorpay, developing reseller VPS modules, or building custom telecom billing solutions, I ensure the solution is reliable and production-ready.
