Hello, and welcome to my personal portfolio! I'm a third year at
UT Austin
studying Computer Science & Electrical and Computer Engineering. I am currently on a gap year completing my Korean mandatory service as a
KATUSA,
working alongside the US Army.
I focus on building practical AI tools for everyday problems. Outside of work, I spend my time playing
classical piano,
practicing Taekwondo (4th deg. Black belt), or working on one of the
personal projects below!
Secure military medical-records system built around a Windows admin station,
encrypted NFC dog tags, and ESP32 field-reader hardware. Gathered and led the team
to 7th place out of 700 teams for the ROK Army Startup Competition. Awarded and
promoted by the Korea Economic Daily News & ROK Department of Defense.

KATUSA Service Try Me!

Combined Forces service, tactical translation, and religious-support operations inside a U.S.-ROK Army environment.

One of roughly four students in my class pursuing both CS and ECE, balancing software, systems, circuits, and math-heavy engineering work.

Two cultures
Spent 11 years in Korea and 10 in America, learning how to adapt across language, school systems, and culture.
I am completing my mandatory Korean military service as a KATUSA, serving as a
56M chaplain assistant in the 8th Army, 2nd Infantry Division Sustainment Brigade
Unit Ministry Team. The role placed me inside a U.S.-ROK Combined Forces
environment, where Korean and American soldiers plan, train, and operate together.
Working in that setting taught me to communicate with precision across rank,
language, and culture, especially when translating tactical context during combined
training.
During bootcamp, I earned Commandant's List by ranking top 4 out of 160 soldiers
in my graduating class. I later received both the Army Achievement Medal and the
Army Commendation Medal from Major General Lombardo for tactical translation
services that helped bridge Korean and U.S. personnel during field operations.
I also had opportunities to work with UNC and meet the Secretary of War and USFK
General Brunson, which made the scale and purpose of combined service feel much
more real and inspiring.

At UT Austin, I am studying CS & ECE as one of roughly four students in my graduating
class pursuing both Computer Science and Electrical and Computer Engineering. The
path exposed me to two demanding ways of thinking: software abstraction, algorithms,
and systems on one side, and circuits, hardware constraints, and math-heavy
engineering on the other.
Accepting that workload also opened doors to competitive student organizations and
department-level opportunities. Through
Texas Convergent,
I built an NFC sleep alarm and pitched it to more than 200 students in the
organization, which pushed me to think about engineering as both a technical build
and a product story. I also had the
chance to interview faculty applicants to the ECE department, giving me a rare look
at how a top engineering department evaluates future professors and research
directions.
On the research side, I led paper discussions with two PhD students through
DiRP,
UT Austin's Directed Reading Program for computer science. Those discussions made
research feel more active and conversational: not just reading a paper, but asking
what assumptions it makes, where the method breaks, and how the idea could turn
into something buildable.
Taking both majors has often meant carrying a workload beyond what felt comfortable.
Over time, that became useful training. It taught me how to break large technical
problems into pieces, keep moving when the schedule is tight, and build projects
that respect both product behavior and engineering limits.
I spent 11 years in Korea and 10 years in America. When I was 10, I moved to
Oklahoma with my mother and entered public school before I could speak English.
That experience was uncomfortable, but it became the first real proof that I could
rebuild myself in a new environment by observing carefully, asking for help, and
improving a little every day.
After three years in Oklahoma, I returned to Korean middle school and experienced
the typical Korean academic system: repetition, memorization, long hours, and
constant comparison against peers. I learned discipline from it, but I also realized
that simply competing inside a fixed track was not the way I wanted to grow.
I then spent a year as an exchange student in Missouri. COVID-19 broke out during
that period, so the normal exchange-student experience disappeared almost overnight.
Instead of treating the year as lost time, I tried to get something meaningful out
of it by helping create virtual activities that local students could still join and
use to stay connected.
Later, when I decided that I wanted to attend college in the United States, I applied
to The Stony Brook School in New York. Living there gave me a broader view of the
U.S. beyond the Midwest, and being near Renaissance Technologies sparked my early
curiosity about quantitative finance: the idea that mathematics, computing, and
markets could intersect. I see myself as a true combination of Korean and American
cultures, shaped by both systems rather than only one.
