ABOUT

Solutions-driven full stack developer with a passion for designing beautiful and intuitive UIs.

Hi! I am Kevin Lin, a full stack developer based in Vancouver, Canada. My professional journey has taken me on many twists and turns. From modeling reactions as a chemist, automating excel sheets at a trading company, to working now as a full stack developer, I am always looking for better and more efficient ways of doing things.

As a full stack developer, I enjoy using my solutions-driven work ethic, my incessant love for building things, and my unquenchable thirst of learning new things to make a difference. That is why I am excited to make a big impact at a high growth company.
