Mariusdev is an independent software engineer and entrepreneur based in Germany — building profitable digital products since 2021, entirely bootstrapped, no external funding, no team.
After completing a Software Development Ausbildung in Germany, he took the independent path — shipping mobile apps, SaaS platforms and web products that generate recurring revenue at scale. Every product built solo, from architecture to launch to growth.
He holds an active presence in rstforums.com — one of the most established cybersecurity communities in Eastern Europe.
The profile is rare: a technical founder who writes the code, ships the product and scales the business — without asking for permission.
