Summary

I am Ermiyas Annisa, a graduate from Aalto university in Computer Science (MSc.). I have a BSc in IT from Metropolia University of Applied Science, Finland, and a bachelor’s degree in Electrical Engineering from Arbaminch University in Ethiopia. I am a self-motivated software Engineer with 12+ years professional experience. Fluent in C# (.net Framework .net Core), Python, Java, JavaScript and web development languages. Possess a strong practical working knowledge of relational and non-relational databases and cloud development. I have worked in an agile development (SAFe, kanban), DevOps, and water-full methodologies. I engage in software development life cycle by developing, writing various tests, automating solution deployment and validating the functionalities to meet the solutions technical and non-technical requirements. During my master’s studies, most of my research work involved tackling machine learning problems, information visualization, neural networks, data mining, clustering, time-series analysis, information retrieval and natural language processing. I am constantly updating my personal and professional technical skills with the current trends and best practices. The skills I have developed through my studies, in the industry and personal endeavors are the grip to my achievements and this will make me a great asset to various Software Engineering positions. Besides that I am a very hard-working person, to say the least, who strives a lot to achieve new heights.
