    Struggled to declare a major the 1st 2 yrs of college. Had too many interests and considered and took classes in Math, Physics, Theatre, Gender Studies. Sat in a graduate law school class on constitutional law.

  • 2016

    Tried my first computer science class in C language and barely made it through...

    Given that I had never heard of programming up until this point, I was very frustrated with the world of Computer Science I stumbled upon. I stopped taking CS classes until 2017.

  • 2017 - 2019

    Took my first machine learning class and got completely hooked!

    I found that machine learning is a combination of my biggest passions including math, probability, and science fiction lol. Took Artificial Intelligence, Natural Language Programming, Computer Vision classes and excelled in all of them. There was not enough joy in computer science without the element of futuristic science fiction. I found my area of computer science and cannot be happier with my choice of major.

  • Summer 2017

    Web development internship at a human rights organization.

    This was my first CS related professional experience. I didn't have any experience with web dev or content management systems (CMS). But I did version migration on the organization's main site in Joomla and revamped it completely by implementing the design by web designers.

    Created a graphical user interface to display hyperloop real-time navigation information using sensor info obtained by Arduino.

  • Summer 2018

    Machine Learning resesarch internship at GEIRI North America.

    I was entrusted to pilot a project to create the first power grid Artificial Intelligence to control contingencies and assist human operators. I used Deep Reinforcement Learning and created an AI which could bring system status back to normal by changing system settings. The paper I coauthored based on this model I developed was accepted by IEEE and was award Best Conference Paper Award at the 2018 IEEE PES General Meeting. I cannot be more proud for this honor by such an esteem technical organization!
