Back to original languageAbout Christopher
I am the CTO of Clasing, a language EdTech that brings AI into real production: bootstrap, profitable, €1M in monthly recurring revenue and thousands of students using our AI every day.
My work is not demos or POCs. It's AI that holds up in production, with paying users and real metrics. I design and build the backend that supports it: LLM architecture, multi-tenant systems, data pipelines. Stack: Node.js/NestJS, Go, TypeScript, PostgreSQL, and AWS.
Outside of Clasing, I build open-source tools for AI agents: Neurox (persistent memory for agents) and Skynex (multi-agent orchestration).
What I can do for your company:
· AI/LLM production architecture audit — what fails, what scales, and what it really costs.
· Scalable and multi-tenant backend design.
· 1:1 technical sessions for architecture and AI decisions.
I'll tell you what works, what doesn't, and where the real risk lies. If you want to put AI into production without crashing, let's talk.
