Hi, I'mKevin Tang.
A
Always striving to push the boundaries of technology around us to benefit the communities we live in.
About
As a Professional Software Engineer, I always try to push my limits. Ever since I was a kid, I would always try to seek out new projects and challenges to build and grow myself as a person/engineer. Through my experiences, I always seek to network with everyone along my journey, trying to understand the community around me and always offering help to those in need.
Looking for an opportunity to work in a full-time position to challenge my skills and experience in Software and Firmware and also grow myself as a valuable asset.
