Safe Workplace (for Amazon)

Developer

The creation of a new app for Amazon where workers can report work-related issues. On the frontend, Ivan helped to implement a system for creating requests for specific incidents. He added the ability to add video/photo/audio materials to the application. A distinctive feature of the project was the creation of a user anonymity system, which allows employees to create tickets and communicate in real-time with the internal security hiring or qualified psychologists, but with the ability to hide their identity. In addition to a regular user account, the system had to allow for the designation of different types of accounts with different sets of administrator rights.

Routinr

Developer

Routinr is a platform for influencers (bloggers) and subscribers. Ivan integrated a notification system and configured it to work according to the local time zone of every individual user around the world. Ruby on Rails was used as the server-side technology. Ivan helped develop a platform admin panel from scratch using only RoR. He also created an admin panel that allows administrators to manage users’ accounts including resetting a user's password to suspend their work as well as the ability to delete accounts, etc.

Scale Fluence

Developer

Scale Fluence is a platform for negotiating and implementing commercial contracts. Ivan was required to make a number of improvements to the admin panel for this project. Its interface lacked convenience and useful details such as statistics about users, etc., so Ivan added a new page containing all of these details. Another task he undertook was to add an Ahrefs hiring function to the platform and set up website SEO analysis to list a better choice of publishers when searched by certain domain criteria.
