About Me

My photo
Erwin C. Salarda
Philippines
My bread and butter has always been computers—my life revolved around everything tech until I started working at Veritek Incorporated, a trusted dealer of automotive service equipment here in the Philippines. I am currently with the company, handling installation, training, and after-sales support. My expertise is in computerized equipment, specifically OBD scanners and wheel alignment systems. I was trained by Launch X431 in Shenzhen, China; by Lawrence Wheel Alignment in Guangzhou, China; and also by 3Excel for wheel alignment. I continue to improve my expertise by doing deep research on every topic I publish on this new blog of mine. I hope you find this blog helpful. Thank you!
