Context

A preschool runs many workflows at once: student records, service registration, tuition calculation, fee collection, and notifications to parents. Each one shows up in several apps, for several roles.

A small change to a business rule, like how tuition is calculated for a registered service, could touch the parent app, the teacher app, and the admin web at the same time. When edge cases weren't found before development, they turned up late in QA or in production.

1. 01Worked with stakeholders to turn requests into concrete flows and screens.
2. 02Before estimating, listed the business rules, exceptions, and which roles, screens, and data each change would affect.
3. 03Agreed on the solution with Backend, Frontend, and QA early, and helped write the test scenarios we used for acceptance.
4. 04Built and maintained Angular web and React Native mobile features, including role-based and package-based access.
5. 05As Scrum Master for a 6-person team: ran ceremonies, tracked progress, cleared blockers, and helped analyse production bugs.
