Capabilities

Backend Systems

The part of an app you don't see — accounts, payments, data. I build the core systems teams rely on, from students-teachers-admins to browsing, checkout and delivery.

Performance

I tune systems so pages load quickly and stay smooth, even under heavy traffic — improving how data is stored, cached, and fetched.

User data is protected with proper access control, authentication, and secure practices baked in from the start.

Repetitive work — scheduling, reporting, order tracking, SMS and email updates — gets handled automatically so teams can focus on what matters.
