I have 8+ years of experience in software engineering, covering Configuration Management (CM), Build / Release Management, Process Automation and Script Development for which I have also been rewarded. Among major and recent accomplishments was conceptualization and implementation of an “END TO END” automation of Product Release process using "Continuous Integration" allowing “24 X 7 X 365” execution of build and test libraries at Ness Technologies. Most popular features were graded alert system and log management etc. The system empowered development and management by giving them real-time alerts on build/test breakages covering 1.5 GB code across 3 GIT repositories and compiling build metrics. I could thus be of particular value to you as an Atlassian product administrator, CI tool administrator, SVN/GIT administrator, Cloud Architect or DevOps Engineer.
