Raj Gupta — Founder · Full-Stack Developer
I build software that solves real problems.
Founder, SymphonicGrow · Open to freelance
About
I'm a full-stack developer who believes technology is worth building when it solves a real problem. Since 2019 that has taken me from freelancing on Fiverr, to leading an engineering team, to building my own products.
100+ clients on Fiverr, then Head of IT and Lead Developer at KYC Management through 2024, shipping enterprise identity and compliance systems. Today I run SymphonicGrow — building SaaS end to end, and still taking freelance work I care about.
When I'm not shipping, I'm mentoring developers or pulling apart whatever just happened in AI.
