Developed new features for our new desktop streaming app that hosted 3 events completely virtually in 2020 and 2021, including challenging on-call during the event itself.

Softpoint Solutions (now Version 1)

Jan 2017 - Mar 2020

I was a front end engineer in teams working on contract projects for banking and insurance clients, building apps and forms in React, Redux, Webpack and Typescript. Learned a lot working in scrum teams with product owners and scrum masters. Lot of early React changes happened during this time (classes to hooks, rise and fall of Redux, etc). Attempts were made to use Flow.js instead of Typescript; I think this was a mistake.

Workday, Inc.

Dublin

May 2011 - Jan 2012

International provides Human Capital Management(HCM), Finance and Payroll solutions using a cloud-biased web application. I was responsible for the creation and maintenance of test scenarios for our automated testing systems. Worked in a Scrum/Agile environment with 1-week sprints and 3-month major release cycles. New test cases were created for new features in releases, and test scenarios had to be running 100% before deployment of a new version took place. Also had to verify issues closed by my colleges as "Ready for Customer". Used in-house tools and Selenium for automation, Atlassian toolkit for issue taking, build management, internal wiki, etc. Fun Story: A test case once failed because a test was checking for numerical age instead of date of birth, causing the test to fail on an annual basis.
