I'm Ijaz Khan
Senior Full Stack Developer
About me
I am a Senior Full Stack Developer with 5+ 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
5+ years building production software across SaaS, healthcare and AI products. Scroll through, or tap a role to open it.
- 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.

Questions founders ask before we start
Clear answers about scope, collaboration and turning an idea into reliable production software.
Explore every answer01How do I hire the best full stack developer for my project?
Look at shipped products, not certificates. A strong full stack developer can show you live projects, explain the architecture decisions behind them and talk comfortably about both the database and the pixel. Review case studies, have a short technical conversation about your idea, and judge how clearly they explain tradeoffs. If they make complexity sound simple, that is the one to hire.
02Where can I find a senior full stack developer for a startup?
The best senior developers are rarely on bidding marketplaces. Look for people who publish real case studies, write about their work and can be verified through live products and LinkedIn history. Referrals and direct outreach to developers whose portfolio matches your product type beat posting a generic job ad.
03Should I hire a freelance developer or a development agency?
An experienced freelance developer gives you senior hands on your code at a fraction of agency rates, direct communication and no account-manager layer. An agency makes sense when you need five or more people immediately. For MVPs, SaaS products and AI features, one senior full stack developer usually ships faster than an agency team of juniors.
04What should I look for when hiring a software developer?
Three things: evidence of shipped production work, communication you actually enjoy, and honesty about what they do not know. Skills can be verified in an hour; those three qualities decide whether your project succeeds over months.
05How do I evaluate a full stack developer before hiring?
Ask them to walk you through one real project end to end: why that stack, what broke, how they fixed it. Vague answers reveal copied portfolios; specific ones reveal experience. A short paid trial task on your actual problem is worth more than any whiteboard interview.
06Is it safe to hire a remote developer overseas?
Yes, if you verify work history, use clear contracts and structure payments around milestones. Remote-first collaboration is standard now; what matters is a verifiable track record, responsive communication and code delivered to your own repositories from day one.
07What questions should I ask a developer in an interview?
Ask about a production incident they caused and fixed, how they decide what not to build, and what they would cut from your idea to ship sooner. These reveal judgment, which is what you are actually paying a senior developer for.
08Can one full stack developer replace a whole team?
For an MVP or a focused product, yes. One senior full stack developer covers frontend, backend, database, deployment and integrations without coordination overhead. You add specialists later when the product proves itself and specific bottlenecks appear.
