I have become the only thing I always hated in a developer. Building a project without a proper documentation.
As a solo developer in a company where I have to do database architecture, front-end, back-end, testing, NETWORKING (I am the most ignorant guy when it comes to networking), product design, there is no time for documentation.

But hey, I have structured the project, files and functions (with comment, parameters type and return type) properly and I understand what I've done even after 4-5 months without touching that specific project so I got that going for me which is nice... I guess.
