Back to original languageAbout Oskar
13 years of software development, started at 12. Ex-Startup CTO with multiple products from zero to production.
Today, I build software systems and autonomous AI agents that take over real business processes. Cloud-native architectures on AWS. TypeScript, Go, Elixir. Every layer.
On the AI side: No chatbots. Autonomous systems that understand context, make decisions, and handle exceptions. Multi-agent orchestration, guardrails, observability. Runs daily in production.
What sets me apart: I understand both worlds. The architecture that needs to be solid, and the AI that builds upon it.
