Nathanael Brian

B.S. in Computer Science at the University of Maryland, College Park

Hi! My name is Nathanael Brian. I am an undergraduate at the University of Maryland, College Park. I have attained my bachelor’s degree in computer science, with minors in actuarial mathematics and technology entrepreneur. I am currently looking for a full time opportunity as a software engineer or a software developer. I am open to other technology positions as well.

I have plenty of work experience. Besides doing part-time jobs during my time at the university as a tutor and teaching assistant, I also did two internships. My first internship is in Deloitte consulting, where I joined a digitalization project for an OEM manufacture company. My second internship is at Citibank as an operation and technology summer analyst. I joined the Citibank Data onshoring project, where I managed application testing with 28 consumer banking departments. I also coordinate communication between Citibank’s team and key stakeholders like Visa and MasterCard.

Besides the internship, I joined research at the University of Maryland to build a web scraping application used by the psychology team to detect action words in newspapers. I also research speech recognition APIs and see how they perform in adverse conditions such as low audio input, background noise, etc.

Besides technical skills, I also have good soft-skills, specifically, my leadership skill. I am the president of the Indonesian association at the University of Maryland. I created this group when I was a freshman. There was no Indonesian group at the university when I first entered. My responsibility is to help Indonesian first-year students who just joined. I also organized some social events and connected our group with the main Indonesian group in Washington, DC.
