Tech Lead & Architect
Mihail Leybuk-Galin
Direct Architectural Leadership
Bridging the gap between business vision and technical execution.
I believe that great software is built on rigorous design, not just coding. My approach focuses on deep technical ownership, aligning systemic architecture with long-term business goals.
When you work with me, you don't get an abstracted manager. You get a hands-on architect who designs the core, establishes the technical culture, and leads the engineering team through complex implementations.
