My name is CJ, a developer who is interested and specialized in Rust, C++, TypeScript, Solidity, Go.

There are many things that I find interesting, but if picking those I focus on most, then it would be:

  • 1️⃣ incrementally verifiable and private computation with ZK and MPC (Cryptography)
  • 2️⃣ derivatives, quant trading with machine learning (ML)
  • 3️⃣ parallel computing with software (Hadoop, Spark, Flink) and hardware (GPU/FPGA)
  • 4️⃣ secure blockchain scaling with data-availability sampling (DAS)
  • 5️⃣ programming language theory and virtual machine (PL, VM)

I graduated from SHU and obtained my Master degree in Réseaux et Télécommunications from UTT, France.
During my five-year stay in France, I led the RealTime Indoor Location System (RTLS) at @Ubudu.
Subsequently, I headed the Blockchain Development at @ParaSpace.
Currently, I'm working as a ZK Engineer at @QEDProtocol.

I was ranked #74 on wakatime leaderboard, you can find my current ranking by searching Cheng JIANG.
