I’m kerim0x1, 20, based in Germany. I am a Full Stack Engineer, Agency Founder and Reverse Engineer who takes products from raw idea to shipped system. I own the design, architecture and engineering in between.

I started with web stacks at 11 and expanded far beyond them. Nine years later, I have completed more than 500 projects across web products, FiveM, Minecraft, desktop tools, AI systems and game infrastructure for companies and teams in the United States, Germany, France and Spain, including direct collaboration with teams in San Francisco.

Today I run my own agency, work across many products at once and release selected tooling as open source. My work combines full stack engineering, product design, AI automation and detection systems. Selected projects have received honorable mentions from Awwwards and other design platforms.

I ship production AI agents: support agents, custom lead agents and durable Eve agents. They are built with the AI SDK, Vercel and Claude, persist into PostgreSQL, and learn from that database automatically.

My security research focuses on exploit behavior, cheat detection and fingerprint based identification. The system detects established and emerging clients and tools including OpeSec, ExploitPreventer, Wurst and LiquidBounce. In one external DonutSMP research run, I tracked more than 1,110 suspected cheater accounts within twelve days without having any access to the server.
