Technology

Backend - Spring Boot

The backend is a Spring Boot application written in the Java. Spring Boot was chosen as it is the current de facto standard for writing web apps in Java making troubleshooting mush easier due to the abundance of resource material on PluralSight, StackOverflow, etc.

Database - Postgres

Data is stored in a Postgres database. Postgres was chosen as it is a popular and reliable database. Postgres supports some handy features such as json columns which I use to store the entries data (which are basically a maps of string → string).

Deployment - Kubernetes

The backend is containerised and deployed to a Kubernetes cluster running on DigitalOcean.

Frontend - Flutter

The app is built using Google’s cross platform UI framework Flutter.
