About

In 2020, I was filling up tons of paper forms for school and I thought to myself, There has to be a better way to do this. I always thought that we can streamline mundane tasks with software, so we can focus on the things that matter. Since then, this has been my motivating factor in building software.

Do it Right. Do it with Purpose.

What I've Been Working On...

Currently, I am a Junior Software Engineer at Freelancer.com, working on the Trust & Safety team. I am responsible for building and maintaining systems that ensure the safety and security of our users at the application level, such as phone verification and fraud prevention systems.
