About Chuniversiteit

Hello / Hoi / !

I’m Chun Fei Lung. “Chun Fei” is my given name, “Lung” is my family name. Native Cantonese speakers can pronounce my name as 龍振飛, but should otherwise not try to write or speak to me in Cantonese. I’m a native Dutch speaker, so everyone else can call me “”, for which the preferred pronunciation rhymes with “dissertation” when spoken with a thick Dutch accent.

My pronouns are he/him and all my friends are white, so if you are trying to hire me for a tech position I’m probably not a great diversity hire.

I often use Chuniversiteit (rhymes with “shite”) as my online handle, for no particular reason. Some of my older accounts use the name Diocletianus (does not rhyme with “anus”), also for no particular reason.


I currently work as a full-stack engineer at the IT/broadcasting department of the Nederlandse Omroep Stichting (NOS), a public service broadcaster in the Netherlands that creates news, sports, and event programmes, after having spent almost four years at the Digital department. I’ve also been serving as an elected member of the company’s works council (Ondernemingsraad) since 2021, and will likely continue to do so until 2024.

My previous employers include Rabobank and InTraffic; the first is a multinational banking and financial services company, while the latter is a Dutch software services company that specialises in public transportation and .

A more complete overview can be found in my CV. I’m currently not open to work.


I spent six months studying Computing Science at Radboud University somewhere around 2008 before I got bored and transferred to Utrecht University, from which I received a BSc in Information Science (cum laude).

Additionally, I hold a MSc in Information Studies (also cum laude) from the University of Amsterdam (although I probably spent most of my time at VU University Amsterdam) and a MSc in Software Engineering from the Open University of the Netherlands (alsø alsø cum laude).

I might pursue a PhD or LLM some day, but my priorities lie somewhere else right now. Besides, cherrypicking online courses is more fun.

Tech stack

I don’t have a favourite tech stack, but most of my professional projects are written in PHP. It’s fine.

For my personal projects, I use:

  • JavaScript (or TypeScript) with React if it’s a web app
  • Go if it needs to stay small and nimble
  • Python if I want to use certain libraries
  • Java if it needs to last
  • Kotlin if I’m lazy
  • Haskell if I’m crazy
  • C# if I’m feeling like a developer, developer, developer
  • Bash if I have nothing else available
  • TeX if someone holds a gun to my head

My preferred databases are SQLite and MariaDB. I sometimes use Elasticsearch, PostgreSQL, Neo4J, Redis, and some obscure triplestores. I wouldn’t touch MongoDB or anything else that’s being hyped on Twitter with a ten-foot pole unless I’m building a throwaway prototype.
