Effective Coverage

https://secure.effectivecoverage.com
This project was handed over from a previous developer who for several years supported and developed this insurance agency's back-office policies management web application.

Working directly with the agency owner, I implemented lots of new features, changed the look and feel of the public part of the application (twice), deeply refactored the codebase, and moved it to the Spring Boot framework. I've also designed and implemented several integrations with third-party services.

Dynamika

I designed and led a team that was implementing the bank's front office framework. It provides a modern UI for the operators and allows bank expert developers to easily implement domain-specific operations using the existing bank back-end system.

I designed and implemented a modules management system which provides isolation of custom components and allows them to easily scale the application.
