About Me

Engineering trust into every device and every line of code

Eight years spent between the repair bench and the code editor — solving problems that others label unfixable.

I'm a professional software developer and mobile phone software technician with over 8 years of hands-on experience restoring devices and building software that businesses depend on daily. My work spans firmware recovery, Android and iOS system troubleshooting, computer and Mac support, and full-stack development.

Technical expertise: Android tooling (ADB, Fastboot, firmware flashing), iOS software diagnostics, Windows and macOS system repair, network-related software services, and modern web development with React, Node.js, PHP, Python and MySQL.

Mission & values: to make advanced technical help accessible, honest and understandable. No jargon walls, no surprise pricing, no shortcuts with your data. If a device can't be saved, you'll be told before you pay.

  • Transparent diagnostics first
  • Strict data privacy on every job
  • Documented, reversible procedures
  • Support that continues after delivery
  • Fair, agreed pricing upfront
  • Remote service anywhere in the world
