Experience
myLivit
https://merkleinc.ch/en/references/mylivit-innovative-real-estate-appWhile working for Namics (now Merkle), I had the pleasure of collaborating with a front-end architect in the lead developer role to complete the front end. After a few weeks on the project, the lead developer was pulled off the project, and I took full responsibility for the front end.
As in all other projects at Namics, I turned designs into code and answered questions regarding the front end from all involved, including the business, design, back-end, and client.
