Managed a team responsible for mission-critical systems, reduced delivery time of changes to the production systems.

2013 - June 2016 (3 years 6 months) - Nuremberg Area, Germany
Led, designed and developed several critical software components for instance the asymmetric cryptographic activation mechanism of PRTG. I also developed tools to find abandoned shopping carts that resulted in recovering seemingly lost sales opportunities. Added goldilocks pricing strategy which alone led to ~3% more revenue. Maintained and optimized our infrastructure for these projects using Ansible, statsd and PRTG to deliver more throughput and consume less resources. Successfully introduced Scrum and carefully refined it to fit our needs. I also migrated a large repository from SVN to Git and Gitlab w/o service interruption, setting the ground work for the rest of the company to eventually switch from Mercurial to GIT and reap in huge benefits from Continuous Integration.

Among other smaller project I built a web-based image archive software using BDD and Ruby on Rails. Worth emphasizing is a cascading category-based navigation, a lightbox- based cart, a live translation tool and a drag and drop image uploader. In addition to that I implement an administration interface to manage the entire app.

Rewrote a large portion of the web application at ibusiness.de so it would resemble a modern MVC app more closely. Then redid the Database- Abstraction-Layer, reimplemented all the affected controllers and wrote a new template parser. Designed and applied a way of organizing files inside the project by domains. This brought down development time and error rate significantly.
