有点笨有点猪HI, THERE!
Game Client Engineer at Tencent TiMi · AI for Science, scientific computing & game engineering
I'm Jundou Jiang (often called Davids), a game client engineer at Tencent TiMi T1 Studio, working on core gameplay and the UGC platform of DreamStar.
Before games, I built core algorithms for a commercial CAE pre-processor — geometry editing, automatic mesh generation and mesh quality checking — and my graduate work applied deep learning to flow field prediction and mesh generation, inside the State Key Laboratory of Numerical Simulation for Engineering.
One thread runs through it all — I like making expensive, slow engineering computation fast enough to live inside real products, whether that is a solver, an editor, or a gameplay system. Lately that means Lua scripting and ability tooling for Unreal Engine, and smaller models that make researchers more effective.
Core gameplay development — skills, interactive objects, 3C and systems.
Built the UGC platform from 0 to 1 — map data storage, map editing with AI-assisted generation, visual scripting / story / NPC, and WebUI.
Fixed-point physics engine R&D for deterministic gameplay simulation.
Geometry editing, automatic structured / unstructured mesh generation and mesh quality checking — the backbone of a commercial CAE pre-processor.
CAD geometry kernel research and HPC cluster operation and maintenance.
Deep learning for computational fluid dynamics and mesh generation; participated in a national major engineering project.
Estrogen content analysis in complex food samples; molecular-docking study on the medicinal value of Swertia species.
A Lua scripting solution for Unreal Engine
Community continuation of Tencent/UnLua. Generates static binding tables for declared types to bypass the reflection hot path; ships Luau / Lua 5.5 backends; adds a CPU profiler written into Unreal Insights, a headless debug service, sandboxing and an infinite-loop watchdog.
Data-driven ability editor built on UE5 and GAS
Abilities are authored on a timeline — one ability is one timeline plus a set of tracks (Montage / GameplayEffect / GameplayCue / collision / displacement / branching), and everything lands on GAS primitives at runtime. Assets export to text for Git, logic and presentation stay separated.
Personal homepage + wiki notes theme for Hexo
A self-developed Hexo theme that fuses a personal homepage with a wiki-style knowledge base. A directory-tree engine turns hundreds of Markdown notes into a browsable tree with search, theme partitions, deep/light modes, KaTeX and Mermaid — the theme that powers this site.
A full-stack LLM written from scratch
Data, tokenizer, architecture, pre-training, post-training, inference system and agent applications — the whole LLM pipeline hand-written and turned into reproducible notes.
