At HayahAI, I built a referral commission system end to end with NestJS, Next.js, Prisma, and AWS. It tracks booking attribution, verifies status, and releases payouts, replacing manual spreadsheet reconciliation; it currently handles 3,000+ referred bookings per month.
I also developed a slot-allocation engine for Respective Accommodations’ seat and cabin slots, replacing manual assignment with a controlled, auditable process that prevents conflicting allocations. I designed a travel-agency account and rate-mapping workflow across 100+ partner agencies, reducing onboarding to a single guided flow.
Earlier, I contributed to backend services and database workflows for online ticketing, trip scheduling, booking management, and revenue auditing at HayahAI. I also developed season-event tracking for CESAFI and built and maintained a school intramurals tracker for The Technologian.
