Informazioni su questo servizio

Stuck on a Java bug you can't figure out? I'll find it, fix it, and explain what caused it so it doesn't come back.


I work on production Java systems every day, mostly debugging large codebases I didn't write. I can help with:

- Exceptions, NullPointerExceptions, crashes, wrong output

- Threading, memory and performance problems

- Older Java web apps (servlets, Jetty, Tapestry)

- Bugs inside third-party libraries, even without source code

- SQL / PostgreSQL issues behind your Java code


You get the fixed code, a short explanation of the root cause, and a note on anything else risky I spot.


Please message me with the error and a short description before ordering, so I can confirm I can fix it.

Backend software engineer working on production Java systems for enterprise clients. Most of my day goes into debugging big codebases, so that's what I offer here: finding and fixing Java and JavaScript bugs, and explaining what actually went wrong. Also a competitive programmer (CodeChef 1854, 600+ LeetCode, Global Rank 396 in Credit Suisse's coding challenge), so logic and performance issues are my thing.
