Hi ,
I have 6+ years of full time experience with jenkins and I am writing Jenkinsfile from last 2 years and specifically integration with atlassian products from last 1 year . We have integrated bitbucket with jenkins using groovy scripts for various jenkins plugins such as stash notifier , Pull request builder via jenkins file and other integration like sonarqube integraion with bitbucket.
Please let me know if interested . We can discuss more on your requirements.
Thanks,
Brij
