Hello
I'm Peter

Software Developer based in Vancouver 🇨🇦

About me

I am an active learner who has discovered my passion in software development through self-learning.

After obtaining bachelor degree of social science, I completed the Harvard’s CS50x online course to learn fundamentals of computer science.

With a thirst of knowledge and keen interest in innovative technologies, I have completed my study of Computer Systems Technology at the British Columbia Institute of Technology.
