About this gig

Stuck on an error you've been staring at for hours? Send it my way.


I'm a Computer Engineering student in Spain and I enjoy the detective part of programming: finding out why something breaks and making it work again.


What I can help with:

- Python scripts that crash or give the wrong result

- Java and C programs (compile errors, exceptions, segfaults, memory bugs)

- JavaScript and small websites (HTML, CSS, JS)

- Excel and Google Sheets formulas or scripts


What you get back:

- Your code working and tested

- Comments in the parts I changed

- A short, plain explanation of what was wrong, so it doesn't happen again


Before ordering, please send me a message with your code and the error you see. I'll take a look and tell you honestly if I can fix it and which package fits. If it's not something I can do well, I'll tell you that too.


I reply in English or Spanish.
