AZdev is a searchable library of practical micro-documentation, errors, solutions and general tips, that software developers may perform on a day-to-day basis.

It is a library of what developers usually look up, a quick way for them to find concise approaches to to certain software development tasks.

The particular thing developers would like to do is known as a Task, while process of performing that Task is known as a Approach. A task can have multiple approaches and an approach belongs to a task

Anyone can browse AZdev for tasks & approaches Logged-in users can add new Tasks and Approaches as well as up-vote or down-vote approaches The main entries for both tasks & approaches and user records are stored in PostgreSQL, while extra data elements like explanations, warnings and general notes will be stored in Mongo DB

• Connect to multiple database storage services
• Handling data response errors
• Resolve relations
• Understanding the n + 1 query problem
• Data-loading optimizations with data loader
• Implementing Mutations
• Implementing basic login/logout functionality
