Yifei (Wifi) Ma
Full Stack Engineer | Product Lead
I build anything and everything.
Hi! I'm Wifi.
I started building things professionally in 2017 and never stopped.
I've engineered mail servers that deliver millions of messages a month with 99.99% uptime, co-authored core APIs, developed a web app frequented by tens of thousands of users and shipped a huge range of products over the years.
You can drop me into any environment and I'll hit the ground running.
Here's a bit more about me!

In Chinese, my name means Pegasus, but you can call me Wifi 🤙
First Class Honours in Computer Engineering from University of Canterbury.
In April 2026, my core ongoing project delivered millions of messages across 50+ countries for hundreds of active users. It maintains 99.99%+ uptime as usage continues to grow.
What time is it for Wifi?
It is 00:00:00 in Christchurch, NZ
In my spare time I enjoy the company of my friends. A celebrated veteran at the pub and dangerous at any board game, I'm always down to meet new people!
In my youth, I purchased 700 cans of beans for 1c each. Determined to save money, I got through about 300 before I gave up. Can you finish the job?
Beans remaining: 400
I share joint custody of Ricky, formally known as Richard. SHE is ~3 years old (I did not name her), enjoys scratching couches, getting into fights and bringing home rodents. She is a rapscallion of the lowest sort but I love her.
It has been 0 years, 0 months, 0 days, 0 hours, 0 minutes, and 0 seconds since my first day in the industry at 9:00 AM on Thursday, November 30th, 2017.
For the past two years, I've trained Muay Thai and K1 Kickboxing.
