Task Tracker application

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.
