PROFILE

SUMMARY

As a passionate Freelance PHP Developer, Agile Coach and Linux Administrator, I have garnered over several years in optimizing and automating business processes and enhancing team performance and agility. A solid background in Agile Coaching with various teams has made me a great communicator with a deep focus on teamwork. Throughout my career, I have trained individuals to corporations on PHP development, deploying infrastructures using puppet and docker and how to support teams as a ScrumMaster.
Thriving in constant challenges, I am also the founder and organizer of Agile Dresden, which is a unique initiative to bring the agile spirit to the city of Dresden and to promote collaboration and knowledge sharing. I have received numerous pats on the back for my organizational skills after these events.
I have just started getting deeper into Django and Frontend Development (react, Backbone.js), but I am rather advanced beginner in Frontend terms.
I am very interested in Management 3.0 by Jurgen Appelo and share my knowledge at http://jantz.cc
I also love open source and visit conferences like FrOSCon and OpenRheinRuhr regularly as well as participate in the Fedora Linux Project and the PHP project.

My interest is in the following jobs (Remote):
- PHP development with Frameworks like Symfony 2 (Zend Certified PHP Engineer)
- Agile Coaching for teams to 9 people
- Training teams in Software Engineering
- Setting up linux clusters
- Amazon AWS
- Scaling web applications
- REST API design and implementation
- automating processes
- implementing Zendesk (Certified Partner)
- implementing Atlassian Tools (JIRA, JIRA Agile, Confluence, Stash, Crowd, Bamboo, etc.)
- candidate screening (Developer and SysAdmins)

Always keen on extending my professional network and to hear about potential remote freelance projects and any query, I can be contacted directly via LinkedIn or on c.jantz@vations.de
