At Hostelworld Group, I designed a geospatial polygon search API for the PWA that enabled discovery of 200+ Bali properties, drove a 12% uplift in regional bookings, and increased quarterly revenue by 5%.
I also designed a zero-downtime PHP/MariaDB migration that remediated 5,000+ production records while maintaining application availability. I collaborated on the PWA V3 migration and redesign, and helped resolve a race condition behind intermittent server errors.
At 390Labs Limited, I optimized an education technology system’s timetable scheduling module with TypeScript, Angular, and PHP Laravel, reducing scheduling conflicts. I also collaborated on a real-time e-learning and voice conferencing app for remote lectures and assessments.
At Patricia Technologies, I built a webhook system for partner businesses to receive and verify crypto payments, and was engineering owner of the business platform’s payment and refund systems. Earlier, at Findworka Limited, I implemented real-time tracking features for its HR solution and improved accessibility on its payroll website.
