Live Tracking & Real Time Location

The live tracking and the real time location of the driver was one of the major challenge our team has overcome. By using Low latency network base protocol and multiple websocket we have ensured this feature works seamlessly. Streaming pipeline has been utilized by our team for the real time locations.

Optimal Route Calculations

Using open street routing machine (OSRM) for the optimal route calculations rather than Google maps proved more powerful and efficient routing machine for system to solve shortest paths in road networks. This is the most important feature on the driver side, so quick processing is must.

Delivery Scheduling

Managing three types of delivery schedule was a crucial task. Future scheduling, Real Time scheduling and 3 hour scheduling managing all this won’t be possible with the monolithic applications. So, here we have implemented a type of microservices to manage all the scheduling data and a queue is managed for the job processing. This proven to be a very optimised and reliable solution.

Server Monitoring, Alerting, Logging and Debugging

Being a very complex and interdependent system deploying the whole system on server is also a challenge. Server monitoring, alerting, logging and debugging is the major factor that our team has taken care of. Also used some high performance computing VMs majorly for the OSRM part to ensure the quality results.

Automatic Failover

To cope up with the particular single module failure or issue we have worked on the automatic failover that will auto scale the real time web socket server. This ensures the recovery of server is smooth and system flow stay intact, that provides a seamless user experience.

24x7 Working System

Allowing consumers and drivers to access the app 24x7 is a very important aspect for the app. Managing all the live requests, job processing and delivery scheduling 24x7 on basis of the drivers availability, selected vehicle type and weight is very must to deliver a smooth experience to the user base.



From smooth delivery scheduling, tracking delivery to secured delivery system with the digital signature confirmation and from optimized routing, live filtered delivery request to scheduling the availability. Every aspect has been taken care of by our team at both consumer and driver level.

Our team have been master in identifying the different uses cases and challenges, brainstorming them and come up with the best solution for that. This project has challenged our team at many different levels. But our team was always up fo the challenge and soon we have a result in our hand as a complete On-Demand Courier Delivery App all set to disrupt the market.
