I'm a third-year CS student who builds software end to end: full-stack web apps, data and ML pipelines, and the occasional game engine written from scratch.

Open to internships & CS roles · hybrid-friendly · graduating 2027

    Performa

    Developer chief of staff CLI

    A local-first CLI in C# on .NET 10 that reads git history and writes the reports I'd rather not: standups, changelogs, branch summaries, loose ends. Multi-repo dashboard with velocity stats, fully tested, ships as a single binary.

    R.A.T.S

    Edge-AI inventory monitor

    A shelf that watches itself. A PIR sensor wakes an ESP32-S3 camera when someone approaches, on-device ML (FOMO MobileNetV2) or a server-side YOLO model counts the stock, and a React dashboard shows live counts, bounding boxes, and low-stock alerts.

    everyAir

    Air-quality forecasting

    Forecasts PM2.5 air pollution across Asian cities using Random Forest regression over historical and real-time data, with geospatial maps and live gauge readouts for each city.

    Myriad

    Ambient sound app for Android

    A native Android app that calms your mind with sounds of your choice. Built in Kotlin from a clean Gradle project up.

    PocketJS

    2D RPG engine, from scratch

    A grid-based 2D RPG engine in vanilla JavaScript on the HTML5 Canvas API. Tile-locked movement, a turn-based battle system, NPC dialogue, and save states, with no game engine or framework underneath. Definitely not inspired by a certain monster-catching game.

03Education

Sejong University

B.S. Computer Science · expected 2027

I'm two semesters out, and my remaining course load is light, which leaves real room for work alongside study. My coursework so far covers web programming, machine learning, and data science.

04FAQ

  • Anything where I get to build. Internships and entry-level roles in software engineering, front end, or applied ML all fit. I graduate in 2027 and my remaining course load is light, so a hybrid or flexible schedule works well on my side.

  • Software that does something you can see. I found coding through the web, HTML, CSS, and JavaScript first, and what keeps me here is games, AI, and anything that feels like the future arriving early. These days that means full-stack apps, ML pipelines, and a from-scratch RPG engine.

  • Python and C# are where I feel most at home. HTML, CSS, and JavaScript sit right beside them, since the web was my first approach to coding and it never really left. The full toolkit is scrolling around in the stack section above.

  • Yes, and openly. I work with Claude Code and treat it like a very fast pair programmer. I still read and understand every line that ships, because I'm the one who has to stand behind it.

  • Seoul, South Korea, where I'm studying computer science at Sejong University. English and Indonesian come native, Japanese and German hold up in a work setting, and my Korean and Chinese get me around just fine.
