Hi, I'm Da-Jin.

I'm a student, software engineer, and problem solver.

I’m a third-year student at Northeastern University studying computer science, driven by solving complex problems and building useful software with large scale impacts. I’m currently a Co-Op as a full-stack software engineer at Alignable.

On the side, I’ve been spending a lot of my time as Technical Director of Sandbox, a software consulting club with 25 members building custom software for researchers. It has been an amazing combination of interesting software problems, high-impact work, and a foray into managing organizations.

Outside of programming, my interests include photography, Vulfpeck, and breakfast.

Software Engineer Co-Op @ Alignable
July 2019 - Present

I'm on the Member Generated Content team working to drive members of Alignable to post more content and engage with the platform and with each other. I have primarily been refactoring our forum to give businesses in the same town and businesses of the same franchise a space to have discuss topics that are specific to their community. I also rebuilt a page to show reviews of national brands written by our members and implemented search and filter.

Software Engineer Intern @ RSA Security
Summer 2018, 2019

I worked as a software engineer to provide our sales engineers with the tools to sell more effectively. My primary project was to develop an enterprise-wide search system to overhaul how employees find what they need. I designed a system that crawls all of our existing sites and servers, indexes all documents, and exposes a single faceted search to find any internal resource. I also led a team of three interns to build a portable system to run product demos across a variety of screen configurations at conferences, trade show floors, and executive briefing centers across the world.

Software Engineer Intern @ MITRE Corporation
Summer 2017

I worked in GPS modernization, a project funded by the U.S. Air Force to provide tools to enable the next generation of GPS satellites and protocols. I lead the development of an interactive map to monitor the health of the GPS satellite constellation in real time and reduced the page load time of one of our sites to less than 200ms and shrank page size by an order of magnitude. I also revamped the UI and performance for CNVRG, an exploration and visualization tool for GPS signal data.

Summer 2016

I worked in Open Health Services, a department contracted by the Centers for Medicare and Medicaid Services to revamp health IT. I contributed to Cedar, a tool that helps evaluate the validity of electronic health records for organizations such as State Medicaid Agencies and Health Information Exchanges. I directed Cedar's transition to test driven development, implemented a RESTful JSON API, and improved usability.

Sandbox Website

I collaborated with five developers and a designer to design and implement the Sandbox public facing website. We designed it meticulously to make a great impression on students and researchers encountering a brand for the first time.

At HackBeanpot, I made Dog Detective, an app for dog lovers to find and pet all the dogs. By crowdsourcing the locations of nearby dogs, Dog Detective makes sure that no one misses a good dog ever again.

A couple of friends and I placed top 24 in Battlecode, an MIT-run competition where each team writes an AI player to compete head to head in a real-time strategy game. I loved getting to put algorithms I learned in class to use.

Log Frog

Log Frog was a simple puzzle game and was the first project I finished and published. Publishing a project taught me how to get from a hackathon prototype to a fleshed out, bug-free game with a tutorial and animations.
