Sergei Kovalevskii

Founder, technician, and the person behind every project at KUSMA. Sergey has over a decade of hands-on experience repairing and recovering computers, hard drives, and networks for homes and small businesses.

He writes the KUSMA Tech Blog to share real stories from the workshop — from data recovery tips to hardware fixes and lessons learned from hundreds of service calls. Every article comes from first-hand practice, not theory.
