Semyon Kotliarenko

I'm Semyon, CTO at UPSTARS since 2020. I lead technology strategy, architecture decisions, and build engineering teams that turn ideas into working systems. My focus is on scalable infrastructure, automation, and AI integration.

I started hands-on, building networks and early websites, then moved through game development, SaaS, and cybersecurity at KeepSolid and WePlay Studios, shipping high-load systems across different domains.

Ask me about engineering leadership, scaling technical teams, system architecture, and integrating AI into product workflows.
