July 2026 - September 2026
- Led Attendify Wrapped, a year-end recap for daycare franchises, from architecture proposal to full build: presented the design to the engineering team, prototyped a demo branch, then built the data model, a cron job computing 17 stats per franchise (care hours, billing totals) without modifying source data, and the dashboard in PHP (CodeIgniter).
- Audited controllers, models, and libraries for SQL injection, tracing user input to database calls; fixed all high- and medium-severity findings with parameterized queries.
- Extended subscription-renewal invoicing with automated email delivery, mark-paid tracking, and overdue detection; refactored it into a mailer library and built the Account Invoices page.
- Built a role-scoped admin activity dashboard with before-and-after field-change logging; fixed the app-wide "Confirm Form Resubmission" error with a Post-Redirect-Get shim.
