At Securepay Sdn. Bhd., I contribute to three business platforms spanning payments, rider management, and inventory. On SecurePay, I developed payment processing, fee calculation, statements, and settlement workflows using Ruby on Rails and PostgreSQL.
I integrated payment webhook callbacks to synchronize payment statuses and transaction records, and used Sidekiq and Redis for background processing. I also debugged payment issues with Bugsnag and added RSpec tests to prevent recurring failures.
On MyRiderID, I developed rider registration and profile-management workflows, including OTP-based authentication. On KoppBT, I built inventory and order workflows and implemented real-time notifications; previously, I developed and maintained responsive websites at Imago Technologies.
