Gig Summary

About this gig

Stuck on a C++, Java, Golang, C#, or TypeScript project? Broken build, failing tests, a feature you can't crack, or a task due soon send it over.

I'm a Lead Software Engineer with 3+ years building production systems, currently running the data platform at a Series A startup. I debug and build in these languages daily.

What I deliver:

  • Bug fixes and debugging: memory issues, crashes, logic errors, failing tests
  • Feature development: new modules built clean into your existing codebase
  • Code review and refactoring: structured, readable, maintainable code
  • Golang backends: REST APIs, microservices, CLI tools
  • Desktop and console applications in C++, Java, C#

How I work:

  • I explain what was wrong and what I changed, in plain language
  • Structured, commented code you can maintain after I'm gone
  • At least 2 revisions included
  • Fast communication, honest timelines

34 reviews on this gig, 5.0 rating. Message me with your project details before ordering so I can confirm scope and timeline.

    I could not recommend Umair enough. He was extremely communicative throughout the project. His meticulousness, quick thinking and skills have been crucial to the success of this project. Since it's rare to find someone this reliable, we're currently exploring other venues for collaboration to make the most out of our relationship.
