Email is the reliable channel. Expect a reply within a few days; I write this blog around a full-time engineering job and a PhD.
Who you are reaching
Jang Young Jeong — AI Product Engineer at Supercent, Ph.D. candidate in Game Engineering at Hongik University, previously AI/game programmer at NCSOFT and Com2uS. Based in Hwaseong, Gyeonggi-do, South Korea (KST, UTC+9).
Full background is on About; selected work and its public evidence are mapped on Portfolio.
What I answer quickly
- Corrections. A wrong version number, a broken benchmark claim, a mistaken reading of someone’s code. Point at the specific line and I will verify and fix it, with the change noted.
- Takedown or attribution requests. If your diagram, screenshot, or text appears in a post and you want it removed or credited differently, say so and I will act on it. No argument.
- Technical questions on a specific post. Especially if you tried the code and it behaved differently.
- Collaboration on agent tooling, multimodal QA, or game AI. The open-source projects listed on the About page are all active. For a paid, scoped review of your own system, see Work with Me.
Paid technical reviews
Outside the free items above, I take a small number of paid, scoped engagements: AI agent/RAG architecture diagnosis, Unity CI & build-automation audits, and multimodal QA design reviews. Best fit is a small team (roughly 2-15 engineers) already shipping something, who wants an outside, technically literate read before committing more engineering time — not a pre-idea project or a retainer.
Each engagement ends in one deliverable: a written findings document with ranked failure modes and concrete next steps, not a slide deck. Full scope and how it runs: Work with Me. To start, email with what you’re building and what decision the review needs to support.
What I will not do
- Publish sponsored or paid posts, or accept payment for coverage.
- Add backlinks or “guest posts” for SEO purposes.
- Provide free consulting on a system I have not seen.
