About Us

PinoyTechnician.com was founded on June 12, 2014 by five individuals — intoy, sAmwell, Alexaliah Gsm, dArk_shAdE & edcuz — with the focus of providing support and creating a dedicated platform for technicians in the Philippines.

Our founders envisioned a friendly, helpful, and professional space where Filipino technicians could connect, learn, and share their expertise in electronics, mobile, and computer repair.

Our Mission

To empower and support the community of Filipino technicians by providing resources, discussions, and guidance that help everyone grow — from beginners to experts.

What You'll Find Here

  • Repair guides, tutorials, and technical discussions.
  • Advice and reviews about tools, parts, and best practices.
  • A helpful community always ready to assist and share knowledge.

Join Us!

Whether you’re here to ask, to teach, or simply to connect with fellow Pinoy techs, you’re always welcome. Together, let’s continue building and supporting the Filipino technician community!

If you have any questions or suggestions, feel free to contact us at: admin@pinoytechnician.com
