# Level Zero (lvl0.me) > Personal site of Martin Yochev — a growth marketer who builds his own tools. Career history, self-built tools and games, and a library of prompts and context-engineering patterns that are free to copy and adapt. Martin has spent eight years in SaaS, EdTech and AI startups, usually as one of the first marketing hires, and writes the prompts and internal tooling he uses himself. The prompt library is the substantive part of this site: each entry is a full, reusable prompt with placeholders, an explanation of the mechanism behind it, and an honest note on where it falls short. ## Core pages - [Work](https://www.lvl0.me/work): Career history from 2016 to now — roles, what each mandate was, and what changed.
