About Mohamed Ali

Java J2EE Consultant for 5 years, with confirmed experience in Java J2EE Web development as well as Java Core and one and a half years of experience with BigData frameworks (Spark, Kafka) in a Hadoop environment. My main responsibilities were with the V-cycle methodology, including 2 years of experience as an IT Project Manager (Java Tech Lead). My Agile (Scrum) experience is only 4 months of practice in a professional environment and workshops during my studies.

I enjoy working on projects where I can gain skills in new frameworks and technologies.
