“Working with Hashir on our React + .NET Website was an outstanding experience. From our very first conversation, he demonstrated a deep expertise in both front-end and back-end technologies. He delivered every feature on time, often ahead of schedule, with clean, well-documented code that required no rework. Communication was seamless: Hashir was always responsive, explained technical details in clear terms, and proactively suggested valuable enhancements.”

    You get a clear scope, timeline and an hourly or fixed-price estimate before any work starts.

  3. Build in weekly steps

    I ship working software in small releases and keep you updated at every step.

  4. Launch and support

    I deploy to production, hand over the code and stay available for fixes and new features.

Questions

Common questions

Short answers before you get in touch.

Why hire one full stack developer and not two specialists?

You get one person who owns the whole feature, from the screen to the database. That means fewer hand-offs, faster delivery and one point of contact.

Do you work from Figma designs?

Yes. I convert Figma designs into responsive React interfaces and connect them to the API.

Can you work with my existing React or .NET code?

Yes. I often join projects that are already running and continue from the current codebase.

Have a project in mind?

Message me on Upwork, WhatsApp (+92 313 2613274) or LinkedIn with your requirements, and I will reply with a practical plan.
