Hi, I'm Da-Jin.

I'm a student, developer, and all around geek.

I’m a second-year undergraduate studying computer science at Northeastern University, expecting to graduate in 2021. I enjoyed working with the brilliant people at the MITRE Corporation and RSA Security and am excited to co-op at Alignable in the fall of 2019!

I chose engineering because it’s a practical way to make people’s lives better, and I love seeing the difference that I can make for others, as well as the technical challenges of problem solving. My favorite projects are always when I work with people to develop their ideas into delightful, robust prototypes and products.

Recently I’ve been focusing on full-stack development, creating custom software for researchers, and trying to teach myself Rust. Outside of programming, my interests include photography, quadcopters, Jay-Z, and breakfast.

Sales Engineering Intern
Summer 2018

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 built an interactive scoreboard for a product training event, boosting engagement and retention for our sales engineers.

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 Software Intern
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.

Dog Detective

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.

Battlecode

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.

Python
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.

A friend and I made an experimental calculator that uses gestures make math easier on mobile devices. Sandbox lets users drag numbers around, lasso select, and edit multiple equations at once.
