2017 – Present


Texas, United States

The Mandate

Build a last mile delivery solution that enables the retailer to on-board and manage a pool of crowd-sourced drivers for same-day home deliveries to customers.

The Solution

Built a bespoke enterprise grade application with the following subsystems: driver on-boarding, order management, driver shift schedule, driver payroll, driver messaging & order logistics.


Key Highlights


Driver Scheduling

As the system grew, it had up to 4,000 drivers accessing it trying to pick up shifts within a period of 15 minutes. This led to huge spike in load on the server and degradation of user experience.

Solution: Overcame the challenge by further isolating the micro-services onto separate instances. Further, a load balancer was configured to ease up the traffic spikes.


Free Range Drivers

The client wanted to enable a driver to pick up and drop off orders from outside their scheduled zone. This would help drivers serve more customers and eventually enable them earn more tips.

Solution: Refined the system to allow drivers to pick up orders from outside their respective zone as long as they clocked into their zone at the beginning of their shift.


Early Schedule Access

The client wanted to reward drivers who were performing well within certain metrics by giving them early access to the weekly schedule.

Solution: Built a feature which kept track of all performance metrics over a certain time period and set their access to the weekly schedule. After this was implemented, the number of drivers accessing the system at the same time reduced thereby improving overall user experience.


Payroll processing

Payroll for the drivers was processed manually on a daily and weekly basis. The weekly payroll calculations were complex and time consuming to process as they were being done manually via excel.

Solution: Captured the entire offline manual process and built an easier, automated online payroll process.
