+## About the project {#about-the-project}
+
+[Certn](https://certn.co/) is an app that wants to ease the process of background checks for criminal records, education,
+employment verification, credit reports, etc.
+
+On Workday I had to work with their client, [Loblaws](https://www.loblaws.ca/), to integrate Certn with their [Workday](https://www.workday.com/) instance. I
+quickly realized that their Workday implementation was not standard, so I had to modify multiple
+open-source SOAP projects (including [python-zeep](https://github.com/mvantellingen/python-zeep)) to work with their setup.
+
+We had 6 months to finish the project and I was able to finish it in only 3 months, which allowed us to
+make changes, improve the security and work on client changes that came up almost at the end of the
+project.
+
+This project led to Certn closing a multi-million dollars a year contract with Loblaws.

+## What did I work on? {#what-did-i-work-on}
+
+-   Worked with Loblaws to integrate Certn with their Workday integration.
+-   Refactored an old implementation they had for Workday, which didn't work for the latest Workday
+    implementation.
+-   Developed multiple jobs to pull data from Workday, convert it to what Certn needs and then process it
+    on their main application.
