I'm Ijaz Khan

Senior Full Stack Developer

About me

I am a Senior Full Stack Developer with 4+ years of experience turning ambitious ideas into production software that real businesses rely on every day. I have shipped SaaS platforms, AI products, healthcare systems, e-commerce stores and WebAR experiences, end to end, from architecture to deployment.

My sweet spot is the backend: Django, FastAPI, Node.js and NestJS, paired with polished React and Next.js frontends. Recently I have been deep in applied AI, building LLM assistants with RAG, vector databases and custom ML model serving, along with the OAuth2, Stripe and DevOps work that separates production products from prototypes. I also build the APIs and infrastructure that power iOS and Android clients.

If you need someone who can own a feature from whiteboard to deploy, and communicate clearly the whole way, let's talk.

Work experience

4+ years shipping production software across SaaS, healthcare and AI products. Open a role to see what I owned.

  • Lead backend development for a microservices product using Django, FastAPI and NestJS, defining service boundaries and API contracts for web and mobile clients.
  • Built an LLM-powered chat assistant using RAG over vector data to keep answers grounded in application content and internal knowledge sources.
  • Implemented the serving layer for an in-house trained image model that processes user-uploaded dental images as part of the product workflow.
  • Owned OAuth2 authentication, Stripe subscription and billing flows, and Celery/RabbitMQ jobs for image processing, notifications and asynchronous workloads.
  • Set up Docker-based CI/CD deployments across AWS and Azure, improving release consistency and reducing manual deployment steps.
  • Review pull requests, support newer developers, and collaborate with product and design to scope features before implementation.
