Siyou Pei
Product Engineer
Joined Ajax in July 2025
What is your favorite project since joining Ajax?
I actually have two:
(1) a next.js rewrite that made the app feel instantaneous: we rearchitected the UI and reduced interaction latency by 60+%, even with hundreds of entries and thousands of components on the page
(2) shipping a recent activities panel that updates automatically via postgres WAL replication: this real-time “domino’s pizza tracker” style panel assures even the most contemporaneous billers that Ajax is capturing their work in real time.
What is your engineering superpower?
Combining product design and engineering to solve end-to-end comprehensive problems :)
Anything else to add?
Nothing is greater than building meaningful stuff. We really care about the product and it feels so great to really make customers' lives easier.
