Two of em.
The first one was making a project following mvc patterns for my last job in which the structure was so easy to follow that my buddy has been able to move allong with it and do more projects out of it. He had a hard time with web development and the boss would have him do it and learn on the job.
To this day that application remains as a "framework" of sorts.
It was made in an unholy comb of js for the front end and classic asp for the backend with restful endpoints and all that shit. I was drunk when I coded most of it.

The other one was during my time in the u.s army. I was a mechanic, a really shitty one mind you. But i knew how to read manuals. All and every task was accomplished to the point in which they had me basically rebuild a vehicle that was beyond salvation. Got it done in 2 months and command was so impressed they set me up as the brigade commander's personal driver and mechanic. I was also drunk for the most part, but then again so where the rest of my brothers.
