Greetings,
Do you need to install Gitlab on-premise? I have done it before for my company.
I have been working as a full-stack developer for a long time and I have got lots of hands-on experience in different aspect of front-end and back-end web design such as PHP/Laravel, Python/Django, JavaScript/TypeScript, Angular, Vue, vanilla CSS, Bootstrap, Materialize and Tailwind.
As a side note, I always keep documentation of my projects in case of any future references or support, so you can rest assured that you have my future support.
Looking forward to hearing from you.
Best Regards
