Building things that matter.
Software Engineer and founder of KoS LLC. I build AI-powered products and design multi-agent systems that automate real workflows — not demos, but tools people actually use every day.
Passionate about AI agents, LLM orchestration, and bringing autonomous systems into production. From mobile apps to AI-driven platforms, I ship fast and iterate with real users. Currently focused on AI adoption strategy and building the next generation of intelligent tools.
