I am an Erasmus Mundus Graduate in Big Data Management and Analytics, jointly organized by TU Berlin, ULB, and ULB as a scholarship holder. The focus of the program is on Scalable Data Analytics, Advanced Databases Systems, Data Warehouse, Semantic Data Management, Cloud Computing,  Big Data Analytics, Business Intelligence, OLTP and OLAP systems, Machine learning, and Stream Data Management. In the past 18 months, I have been focusing on designing data pipelines, performing ETL jobs on Spark, applying OLTP and OLAP queries to relational and NoSQL databases, building data lakes and data warehouses on Google Cloud Platform and Amazon Web Services, evaluating the quality of classification algorithms across open-source ML systems, experimenting with novel ML testing approaches, and analyzing frequent ML bugs

My thesis topic is "On the Problem of Software Quality in ML Systems". The goal is to evaluate the quality of classification algorithms from open-source ML systems to detect ML bugs at an early stage with model pre-train tests, model post-train tests, applying data and model validations to detect concept and data drifts, and experimenting with smoke testing, metamorphic testing, and model behavioral testing to reproduce or find new bugs for image classification and NLP models. In addition, we applied popular static analysis tools to evaluate the quality of four open-source ML software repositories.

I have a bachelor's degree in In from Mekelle Univesity, where talent meets challenges. Owing to my outstanding academic performance and valuable leadership skills, I was offered the role of Assistant Lecturer and Database Developer at Adigrat University in Ethiopia. I taught Database systems, Advanced Programming with Java and Python, Data Structures, and Data Mining with Python for 3 years to about 50 students. Furthermore, I contributed to the University Registration System as a database programmer for SQL Server. Moreover, I worked as a professional Junior Software Developer at Aelaf Technologies, Ethiopia, where I worked mainly on the development of data-intensive pipelines employing relational and non-relational databases. It was a fantastic experience that allowed me to apply cutting-edge technologies to data management problems.

As I advance in my career, It is crucial for me to improve my technical and leadership skills. It is my firm belief that continuing working as a Data Engineer with your brilliant team will unleash my creative potential.
