Faster responses for a busy everyday platform.
The problem
What needed attention
A platform serving rides and deliveries needs responsive services and dependable payments. Slow operations were adding delay to a critical API.
My contribution
The work I delivered
I led the Delivery and Payments squads, working with product managers and engineers on integrations, services, and releases.
- Used application performance monitoring to identify and remove slow operations.
- Integrated Bank Alfalah and Checkout.com payment gateways.
- Built a localization service with support for three languages.
- Designed database schemas, improved queries, and coordinated production releases.
The outcome
What changed
- Reduced the time within which 95% of requests to a critical API completed from about 1 second to 200 to 300 milliseconds.
- Payment integrations handled approximately 500 to 750 transactions per day during the reported period.
- The wider platform handled approximately 140,000 rides a day and 1,500 requests per second. These figures describe the platform, not an individual project result.
