Bianka Panova Academy

Sole developer & project manager

Production class-management platform for a leading Singapore rhythmic-gymnastics academy, replacing an off-the-shelf tool. Parent, coach and admin portals, online payments (PayNow & cards) with GST invoicing, a block-based CMS website builder, and an in-house marketing-automation suite — designed, built and operated solo.

  • Serves 150+ families and 160+ active students
  • Money-safe payments: idempotent, fail-closed webhooks + reconciliation cron
  • Postgres row-level security, TOTP 2FA, full audit log
  • Campaigns, automation flows and segments built from scratch
  • Ranks #1–2 on Google for its core local search terms
