Task Tracker

Task management system designed to improve task organisation and monitoring. It allows users to create, manage and track tasks.

For developers

This project is an example of a supporting backend application in the Go language. It aims to combine high-performance backend with Domain-Driven Design (DDD) and Clean Architecture techniques. Specifically, anemic models were opted as a pattern within the Domain-Driven Design approach

Features

• Clean Architecture. The architecture prioritizes encapsulating business logic and domain concerns. Specific implementations of database/web/events/logging/other are not emphasized.
• High Performance. Designed with a focus on delivering efficient performance and low latency.
• Minimal dependencies. Using Go's rich standard library and idiomatic problem-solving approaches to minimize external dependencies. The project maximizes Go's capabilities.
• Minimal amount of database requests. Aiming for optimal performance by minimizing the number of database requests. Some Domain-Driven Design (DDD) or Clean Architecture (CA) applications suffer from IO performance issues due to excessive querying or complex domain object reconstruction. This project seeks to strike a balance that is easily comprehensible for humans while being less IO bound.
