About me
I'm Hassaan, a full-stack developer who takes projects from idea to production and rescues the ones that got stuck along the way.
I build AI-powered web and desktop apps, Android apps, CRM/ERP systems, and SaaS platforms. I also turn Figma, PSD, or XD designs into working responsive websites, debug and stabilize AI-generated (vibe-coded) projects, and take on standalone coding tasks.
Stack: React, Next.js, Node.js, Python, Django, FastAPI, Kotlin, PostgreSQL, MongoDB, Docker, AWS.
Send me your requirements first. I'll tell you honestly what it takes to build it right, then we get started.
