About

Hello!

I am currently a Senior Software Engineer in Azure for Operators (Cambridge, UK).

My research interests are Computer Algorithms (e.g. Cloud, Blockchain), Wireless Propagation/Channel Modelling and Open RAN. I have quite a few patents on intelligent radiowave propagation algorithms (ray tracing/launching).

In 2006, I completed my BSc (Hons, First Class, 3 A+ and 5 A’s) in Computer Science in University of Bedfordshire. And then with a Fee Waiver Scholarship I started pursuing my PhD research.

In 2009, I was awarded the Marie Curie Transfer of Knowledge Scholarship. I joined EIA-FR Grid Group, GRID and Ubiquitous Computing Group, University of Applied Sciences of Fribourg, Switzerland (Ecole d’ingénieurs et d’architectes de Fribourg) as a Research Associate (Visiting Scholar). During the stay there, I developed parallel and distributed radiowave propagation algorithms via POP-C+ (Parallel Object Oriented Programming C++).

And at the age of 25, I obtained my doctorate degree at Wireless Propagation Modelling University of Bedfordshire. My thesis is “The development of an intelligent ray launching algorithm for wireless network planning”.

Upon PhD Completion, I worked for a cambridge wireless startup software company where I have designed and implemented the cutting-edge Intelligent Radiowave Propagation Engine that was pushed to its limits by using Win32 inline Assembly in the core. See this journal paper: Intelligent Ray Launching Algorithm for Indoor Scenarios – Radioengineering, Volume 20, Number 2, 2011, ISSN: 1210-2512, p.p.:398-408.

From 2013 to 2015, I joined University of Sheffield (Electronic and Electrical Engineering Group) as a Marie Curie Experienced Researcher (Post-doc) where I worked on the software tools (e.g. high frequency ray tracing tools) for wireless and energy efficient buildings.

I published a few conference and journal papers on Radiowave Propagation Modelling.

In 2018, I joined General Electric (GE Smallworld) where I have added the _while loop, regular expression, http library, jwt APIs and many other features to the Magik compiler.

In 2020, I joined Amazon (AWS) where I have contributed to development of several large scale distributed applications in the domain of AWS (Amazon Web Services). I have worked from Day 1 at S3 Object Lambda and witnessed the successful launch of it (18/March/2021).

During my high school Xiamen University Affiliated Keji High School, I have won the third prize on NOI (2002) programming contest i.e. National Olympic Informatics and NOI (2001-Fujian District) in 2002 and 2001 respectively.

Worth mentioning

Occasionally, I contribute to open source projects such as Tron Blockchain (java-tron), Ledger Wallet (app-tron C) and Steem Blockchain (steemd C++).

I am active on social media (Linkedin) and I enjoy sharing my knowledge/thoughts by blogging this, this and this (just another Chinese Blog).

At my spare time, I teach my sons and wife programming and here is my youtube channel and list of videos.

I develop and maintain online tools/APIs for fun such as Weibo API, VPS Database and File Merger.

Currently, I am a TOP 5/100 Witness (Block Producer) of the Steem Blockchain. I am beknown for the contributions (infrastructure, tools, API and services) to the Steem Blockchain.

My favorite programming language is VBScript and my favorite cipher algorithm is rot47.
