Newcomers initialization portal

Customer

One of the top 3 biggest logistic companies in the world

Description

Start is the very first portal newcomers visit when they start with the company. It's a portal that first started as a replacement for Microsoft's cumbersome "Password reset" and "Setup multi-factor authentication" screens, but later outgrew its original intent and became a replacement for the internal complicated process of password resets through helpdesk tickets.

It's based on the idea of community support, where certain trusted employees have the right to reset passwords for other users in their scope of responsibility. For example, a team leader of a sorting line can reset passwords for their workers and can also update their MFA phone settings to help them in cases of lost/changed phone numbers.

This project significantly simplifies the lives of frontline workers and their managers.

The whole solution is built with very low maintenance technologies, which helps reduce maintenance fees to a bare minimum.

Formulating vision, analysis, design and implementation of the whole solution.

Technologies used

• Elixir, Phoenix as a backend framework
• ASP.NET Core as a backend framework for Active Directory connector service
• PostgreSQL as a backend data storage
