LMS Rozumnik.
A full-stack learning management system — courses, grading, live sessions and student analytics in one platform.
Ex-Amazon · Reface · Materialise SQUAD · Enercare. I'm Leonid Ksenchuk — founder, architect & developer. Across a decade I've built 15+ products spanning education, gaming, AI, and civic tech.
In a world of templates & shortcuts, we build software the way it deserves to be built — slowly, sharply, and with intent.
From native macOS and mobile apps to LMS Rozumnik, websites and landings — the bar stays the same: fast, refined, considered.
A full-stack learning management system — courses, grading, live sessions and student analytics in one platform.
Native Mac applications — built for performance, designed to feel at home on the platform.
Production-grade frameworks and AI products built from the ground up — used across every project we ship.
A real-time 3D avatar with conversational AI: Ukrainian-language voice, expressions, and presence — engineered for education, support, and broadcast.
Modular admin framework — drop-in panels with auth, analytics, and user management.
Drag-and-drop landing page constructor — sections, hosting, and CMS in one tool.
A dozen companies founded, two national platforms architected, and a charity built from the ground up — each focused on moving Ukraine forward.
Every engagement follows a tight, transparent sequence. You always know what's shipping, when, and why.
