About this gig

Got a bug slowing you down, or a codebase that needs a second pair of eyes?

I fix bugs, review code, and maintain Java and C# codebases from a single targeted fix to a full audit.

My services include:

Bug fixing: isolate and fix a specific issue in your existing code.

Code review and audit: a structured review of your codebase, flagging risks and improvement areas.

Maintenance: ongoing fixes and small improvements on an existing project.

Refactoring recommendations: a clear document outlining what to improve and why, for larger codebases.

Why choose me?

I have spent several years as the long-term technical partner for an industrial group, maintaining and improving critical applications used daily by hundreds of users. I bring the same rigor to every Fiverr project: careful diagnosis, clean fixes, and clear communication.
