지식과 상상력을 세상에 구현하는 AI 서비스 공학자
from plateer import AIRnD
me = AIRnD.PartLeader(
name = "HaRyeom Jang (장하렴)",
role = "AI Agent Engineer · AI 서비스 공학자",
base = "Seoul, Korea",
work = "Xgen — enterprise LLM platform "
"(retail · finance deployments)",
side = "Geny — multi-agent playground with "
"live avatars & real-time TTS",
creed = "Build what's needed 1–2 years from now, "
"and make it run today.",
)I design and run the full lifecycle of LLM products — training pipelines, GPU serving, agent harnesses, and document-to-context (RAG) systems. By day I lead product development for Xgen at Plateer AI R&D; by night I grow Geny, an autonomous multi-agent city where my experiments live.
|
Autonomous multi-agent system — manage multiple agent sessions, orchestrate long-running tasks, and watch it all unfold in a 3D city playground.
|
Document processing library that turns raw documents into AI-understandable context — analyze, restructure, normalize, then let the model reason.
|
|
AI hands over meaning (spec), not coordinates — deterministic layout engine renders clean diagram SVGs. Built as a Tool/MCP for agents that draw.
|
Chat-driven PPTX studio — restyle or extend existing deck templates by talking to it. Korean-first web UI served at hrletsgo.me.
|
|
Browsers and search built for agents, not humans — an-web (AI-native browser engine) · playwLeft (Rust automation) · pybrowser · googer
|
Semi-automated avatar production platform — AI-redesigned parts on standardized 2D rigs. With geny-avatar: Live2D-style editor + AI textures.

…and 70+ more experiments in my repositories · full write-ups at hrletsgo.me
Trained, distilled and shipped from my own pipelines — all on HuggingFace → CocoRoF
