Core development on a major Chinese education app through high-stakes version iterations.
REAL APP STORE SCREEN
CLIENT OR PRODUCT
Baby English (成长兔英语) — a renowned educational product in China.
MY ROLE
Core iOS developer during major version cycles
THE PROBLEM
A live education product needed sustained iOS delivery quality while product, content, and growth requirements kept changing.
CONSTRAINTS
- •Live App Store product with real users
- •Major version iteration windows (2018–mid 2019)
- •Cross-team coordination with product and content
- •Stability under continuous feature pressure
THE INVESTIGATION
Identified which parts of the client and delivery process were blocking reliable releases, and prioritized work that unblocked the broader team.
THE STRATEGY
Operate as a core developer inside major version cycles: own critical client work, keep regressions low, and ship in cadence with product milestones.
WHAT I BUILT
- •Core iOS features and iteration work
- •Release-path contributions for major versions
- •Collaboration across product and engineering
- •Production maintenance under live traffic
THE HARD PART
Shipping meaningful product changes without breaking a live education experience parents and children actually depend on.
THE VERDICT
- •Participated as core developer through major version updates
- •Product continued to ship on App Store to real users
- •Experience operating inside high-pressure consumer delivery
