Marcus Chen-Liu

I graduated from the University of Bristol with a Master's in Computer Science and moved to London to work as a software engineer in fintech. Three years in, I split my evenings between building payment systems by day and teaching people to code by night.

My tutoring started informally — helping colleagues' partners and friends learn to code during lockdown. It turned out I was quite good at it, and word spread. Now I have a small but dedicated roster of students, mostly career changers and junior developers looking to level up.

My teaching style is direct and honest. I will tell you when your code is good and when it is not, and more importantly, I will explain exactly why. I run my sessions like code reviews: we look at your work together, I point out patterns and anti-patterns, and we refactor until it is clean. This is how you learn to write professional code, not tutorial code.

I am bilingual in English and Mandarin, which helps me work with London's large Chinese-speaking community. But most of my teaching is in English.
