Cloud Architecture and Web Application Development

Actuarial Modernization using emerging technologies and cloud solutions.

- Created, designed, and maintained the lifetime of the core, monolithic backend database using PostgreSQL hosted on Google Cloud SQL.
- Created initial “mock” database for initial development and testing through the final production database used at the initial beta test launch
- Orchestrated and decided the many various cloud services to use throughout the project including a multitude of GCP APIs, Google Maps APIs for real time delivery tracking, reverse geocoding, and route optimization/dispatching, Firebase for mobile app authentication and user management, MPesa/Safaricom APIs for secure payment gateways, Africa's Talking for communications and notifications, and other services.
- Utilized React Native to build both Android and iOS mobile applications for customers, vendors, and riders (deliverers) in conjunction with the orders management API to allow mobile clients to interact directly with the database.
- Designed two administrative dashboards as web applications (one for vendors and one for Powwater admins) to oversee the operations of the system in real-time.
- Created a NoSQL database for document storage related to real-time water quality tests received from the vendors providing the water to customers.
- Wrote all project-wide documentation, from the highly technical to the end-user guides.
- Trained and onboarded new Kenyan developers remotely onto to the project.
