Interests.
What I'm passionate about outside (and inside) of work.
Brazilian Jiu-Jitsu
Training BJJ is how I stay grounded — both literally and figuratively. The problem-solving on the mats mirrors the kind of thinking I do in code: breaking down complex positions, finding creative solutions, and always iterating on technique.
Training
Regular gi and no-gi sessions focusing on guard work and submissions
Competition
Competing locally and learning through the pressure of live matches
Community
The mat is the great equalizer — connecting with people from all walks of life
BJJ also spawned a side quest: Grapplay — a personal project born on the mats. Because apparently tapping out wasn't enough; I had to go home and build something too. See it on the projects page.
Music
A couple of artists and albums that have shaped how I listen.
Oasis
(What's the Story) Morning Glory?
Britpop at its peak. Morning Glory is one of those albums you can play front to back without skipping a track — Champagne Supernova, Don't Look Back in Anger, Wonderwall. Timeless.
Ryuichi Sakamoto
Opus
A final concert recorded in Sakamoto's living room while battling illness. Every note carries weight — minimal, intimate, and deeply moving. A masterpiece farewell.
Art
Building Gallr — a guide to art exhibitions across Korea — turned a passing curiosity into a habit. I gravitate toward minimalism and the post-war Asian avant-garde: work that says a lot by removing almost everything.
Featured artist
Lee Ufan (이우환)
Korean painter, sculptor, and theorist; co-founder of Japan's Mono-ha ("School of Things") movement. His work pares painting and sculpture down to the encounter between a single mark, a stone, a steel plate, and the empty space around it.
From Point / From Line
1970s
Repeated brushstrokes that fade across the canvas — each stroke loaded with pigment, then exhausted, marking time as much as space.
Relatum series
1968 – present
Sculptures pairing natural stones with industrial steel plates. Nothing is altered; the meaning is the relationship between them.
Dialogue
2000s – present
Single grey-blue brushstrokes on raw canvas. The painting is mostly silence, with one deliberate gesture.
Where to see the work
Discovering galleries and exhibitions is also what Gallr is for.
Tech & Engineering

Jetpack Compose, KMP, Kotlin advancements, and the evolving Android ecosystem
AI & Machine Learning
Exploring LLMs, on-device ML, and how AI is reshaping developer tooling
Open Source
Contributing to and learning from the open-source community
System Design
Distributed systems, scalable architectures, and performance optimization
