About Assad Ullah
Senior Full-Stack Engineer | AI Integration | I Own Problems, Not Task
Lahore, Pakistan - 1:04 am local time
That's how I've worked for 10 years.
I've built SaaS platforms from zero to production, architected real-time systems handling live data at scale, and shipped mobile apps on iOS and Android — most recently as a core engineer at a high-growth AI startup, where I integrated OpenAI APIs to power code completion, analysis, and debugging features used by thousands of developers in production.
I don't just write code and disappear. I'll tell you when a feature isn't worth building yet. I'll catch the architectural decision that will cost you three months in six months. And I'll give you a clear technical roadmap so you're never guessing what's happening or why.
What I bring to your project:
→ SaaS & Web: React, Next.js, TypeScript, Tailwind, Material UI
→ Mobile: React Native for iOS and Android — performance-first, production-ready
→ Backend: Node.js, Laravel, Lumen — built for scale, not just for demos
→ LLM & AI Integration (OpenAI, Claude, Gemini — chat, analysis, AI-powered features)
→ Infrastructure: MySQL, MongoDB, Redis, AWS (EC2, S3)
→ Real-time systems: SocketIO, Pusher for live dashboards, chat, and event-driven apps
→ Security: JWT authentication, secure payment gateway integrations
Who I work best with:
Founders and CTOs who are done babysitting developers. If you want someone you can hand a problem to — not just a spec — and trust that it comes back solved, let's talk.
I take on a small number of projects at a time to make sure I can actually show up as a technical partner, not just a resource.
Send me a message with what you're building. If I'm the right fit, I'll tell you. If I'm not, I'll tell you that too.
