Engineering at the intersection of software, AI systems, and hardware.

Leonid Kulcha (Sollem) - Lead Architect & Founder
Sollem • Architect Leonid Kulcha

Sollemdev is an independent engineering studio driven by one human architect and collaborative AI orchestration. We build high-performance software, browser extensions, IoT robotics, and custom hardware systems.

Nothing is taken at “it just works” - we build from first principles down to the fundamental physics and logic underneath. Designing a fluid interface, an AI translation pipeline, an embedded IoT controller, or a pulse-forming network share the exact same craft: structural rigor, zero fluff, and knowing what to strip away.
