About this gig

Not every project needs a full development team. Sometimes you just need a skilled developer who can understand your problem and solve it cleanly without the back-and-forth or the delays.


I'm a Senior Full Stack Developer with 3+ years of experience across Python, Java, C, C++, JavaScript, and more. I help clients fix bugs that have been blocking them for days, implement features in existing codebases, write clean algorithm solutions, and build small, fully functional programs from scratch.


Whether you have a broken script, a logic error you can't trace, a feature that needs adding, or a small application that needs building, I can handle it. Code is delivered readable, efficient, and properly commented so you understand exactly what was done.


I work with Python for scripting, automation, and backend logic. Java for object-oriented applications. C and C++ for algorithms and performance-critical tasks. I also cover JavaScript, PHP, SQL, Bash, and Linux environments.


Message me with your requirements before ordering, and I'll confirm if I can help and give you an honest timeline.

    Great experience working with Hassaan! He quickly identified the root cause of multiple React errors and optimized my code for better performance. My app is now running smoothly with no console issues. He explained everything clearly and delivered ahead of schedule. I’ll work with him again for debugging and frontend optimization.
