Expan USSD

Inspiration

It is necessitated by the current Covid 19 pandemic where the government has put in place measures/guidelines that require PSVs to have a manifest of their passengers for easier contact tracing, in the event of a positive case being identified among the passengers.

What it does

This project aims at creating a solution that addresses that by:

• Passenger msisdn as a reliable contact detail
• Saving time in the collection of customer details
• Digital storage of the manifest in the cloud
• Easy acces to the manifest i.e downloadable pdf

Usage

How I built it

As it currently is it's built over a two week period from design to working concept. Designing the interfaces with figma was the best decision I made since I had a lot of ease in coming up with github issues and developing at a fast pace with clear goal in mind

Challenges I ran into

• Connecting services in the cloud e.g database, redis memory store, running container,networking
• Working with docker and successful deployment
• USSD set up. My first time working with USSD
• Handling user session and proper routing during USSD use

Accomplishments that I'm proud of

• Handling a user session from start to finish
• Dialing USSD code and seeing it working

What I learned

• Importance of the design phase
• Reading product documentation is important
