I'm Ijaz Khan
Senior Full Stack Developer
About me
I'm a Senior Full Stack Developer with 5+ years of experience turning ambitious ideas into production software that real businesses rely on every day. I've shipped SaaS platforms, AI-powered 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've been deep in applied AI — LLM-powered assistants with RAG, vector databases and custom ML model serving — plus the OAuth2, Stripe and DevOps plumbing 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.

- Built and maintained client-facing web application features using JavaScript, TypeScript, React and Next.js.
- Integrated APIs, converted UI/UX designs into reusable components, and resolved layout, responsiveness and cross-browser issues.
- Built form-heavy screens with validation and clear error handling, keeping state predictable with modern React patterns.
- Worked alongside senior developers to debug issues across the frontend, API and database layers, building the habits I still use today.

Ask me directlyWhat kind of projects does Ijaz Khan build?
Production SaaS platforms, AI and LLM applications, healthcare products, real estate platforms, e-commerce stores and WebAR tools. Recent work includes DentaSmart, an AI dental analysis platform, and OnMLS, a flat-fee real estate listing platform. Case studies live at ijazkhan.com/projects.
Read full answerWhat do you need from me to start a project?
A clear description of the problem and who has it, examples of products you like, any existing branding or content, and decisions answered quickly when asked. The single biggest thing a client controls is feedback speed.
Read full answerDoes Ijaz Khan work with existing codebases?
Yes, comfortably. From refactoring legacy Django services to extending Next.js applications, he joins existing teams and codebases as readily as he starts greenfield builds, beginning with a code audit and a prioritized plan.
Read full answerDo freelance developers charge hourly or per project?
Both are common. Fixed price works when scope is genuinely fixed; hourly or weekly works for evolving products. Many experienced developers price the first milestone fixed to build trust, then move to a weekly rate once collaboration is proven.
Read full answerHow does Ijaz Khan communicate during a project?
Clear scoping before work starts, weekly progress updates in plain language and demos of working software rather than status theater. Clients always know what is done, what is next and what it costs.
Read full answerWhat happens after my website or app launches?
The first two weeks surface real-user issues, so plan a stabilization period. After that: monitoring, dependency updates, backups and an improvement backlog driven by actual usage data rather than guesses. Launch is the start of the product, not the end of the project.
Read full answerIs Ijaz Khan available for freelance projects or full-time roles?
Yes, both. I take on freelance builds end to end and I am open to full-time senior engineering roles, working remotely with teams worldwide. The fastest way to start is the contact form at ijazkhan.com/contact.
