AI Full-Stack EngineerClass of 2026

YONGQUAN CUI

Cross-platform front end, Node.js services and AI features — shipped end to end, from requirements to release.

CY AI full-stack engineer since 2022

Building interfaces, shipping products, bringing AI into every detail.

I work across the whole stack: ArkTS and Vue on the client, Node.js and MongoDB behind it, then the AI features that make the product worth opening twice.

About

I like the part of the job where a requirement turns into something people can actually use.

Two years in, that has meant a warning-and-monitoring platform for my university, a HarmonyOS app rebuilt around MVVM, and an internship where I owned eight modules end to end. Most of my work lands on the front end, but I keep going until the API, the data model and the prompt all make sense too.

Experience

  1. 2025.07 – 2025.09

    Shenzhen Yumni Technology

    Front-end developer intern

    • Owned 8 modules and 17 screens on the consumer app — account deletion, feedback and education verification among them.
    • Extracted 6 shared components (global feedback toast, content card, note dialog), removing ~800 lines of duplication and cutting similar work by about 30%.
    • Fixed overlay drag jitter on real devices so the interaction behaves the same on H5, mini program, iOS and Android.
    • Built message dispatch and creator review on the admin side; daily review throughput now passes 5,000 items.

How I work

  • Ship it, then make it right — a working version teaches more than a perfect plan.
  • Understand the layer below the one you work on; that is where the bugs live.
  • Write it down so the next person does not have to ask.

Around the work: the OpenHarmony community, mathematical modelling, and whatever AI tooling showed up this month.

01 Work Case studies, systems and everything shipped. 02 Life Travel, side quests and the rest of it.

Selected

The first three are shipped work straight from my CV. The rest of the grid is an archive of studies and side projects kept from the original template.

Twelve more projects live in the archive.
