Software Developer / Team Lead

  Taipei, Taiwan

Experienced C++ programmer, AI/ML developer and HPC developer. I do open source maintenance for fun.

         

Skills

Modern C++ 20/23

I have been using C++ as my primary programming language for more than 13 years. Now I follow the latest standards and  technical drafts to write expressive, high-performing programs. Familiar with new language features like PMR, coroutines, parallel STL and Transactional Memory.

High Performance Computing

HPC coding skills. Developed libraries that take advantage of OpenCL to run on the GPU. I also have experience with OpenCL on FPGAs for building DNN accelerators. I'm also familiar with parallel computing on CPU and am very aware of the traps of NUMA as well as the effect of caches.

Linux and *NIX

I have been a daily Linux user for more than 10 years. I have maintained university research clusters. Now using Arch Linux as my daily driver. I'm familiar with systemd and it's startup process. Also able to operate *BSD servers. Now learning the internals of OpenBSD.

Alternative Web Technologies

Experienced with alternative/distributed solutions. Solving problems with special needs. Such as OpenDHT (decentralized KV store), Yggdrasil (secure routing), GNU Name System (decentralized name resolution) and Gemini (simple document transport).

Machine Learning / Data Analysis

I'm an active member of Numenta's HTM theory research community. HTM is a ML model and theory based on neural science. I'm also familiar with CERN's bid data analysis framework, ROOT. I deployed analytics services based on ROOT that solve large problems efficiently.

Yada..yada....

git, Lua, ffmpeg, Rust, Common Lisp, open source dev, written Gnome extensions, those stuff... I'm confident in the diversity of my skill set and my ability to understand then fix freestanding bugs that I find.
