👋 Hey, I'm Harsimarpreet Singh Sahota

Full-Stack Developer (React • Next.js • TypeScript • Node.js • MongoDB • Docker • CI/CD)
I build production-grade software & AI systems used by real users, startups, and student communities in Calgary.
📍 Based in Calgary, Alberta


🌟 About Me

I don’t just build projects — I ship real products with scalable backends, clean frontends, and intelligent AI layers.
My work blends:

  • Full-Stack Engineering (MERN)
  • AI Integrations (OpenAI / Gemini)
  • DevOps (Docker + GitHub Actions CI/CD)
  • Prompt Engineering
  • Startup product velocity

I've built & deployed full-stack AI apps like Finvoice AI and InterroGen AI, each engineered as production-level systems with authentication, analytics, cloud deployments, and real user adoption.

I'm also the Lead of GDSC @ SAIT, where I’ve mentored many developers and organized large-scale AI & full-stack workshops.
