At Keylane, I contribute to the development of robust, event-driven systems using Java and Axon Framework. My responsibilities include designing and implementing scalable back-end solutions and optimizing system performance. Additionally, I am actively involved in the development of a new front-end application using Angular, working closely with the front-end team to integrate back-end services seamlessly. My role also involves collaborating with cross-functional teams to refine business requirements, improve system architecture, and enhance overall software quality.

I completed my master's in Data and Web Science at Aristotle University, specializing in Machine Learning and Big Data. The program covered advanced topics in data processing, artificial intelligence, and large-scale analytics, providing hands-on experience with modern frameworks and methodologies.

As part of my master's thesis, I developed Mediator, a tool for predicting the psychodemographic aspects of Twitter users. By leveraging machine learning and big data techniques, Mediator analyzes user-generated content to infer characteristics such as personality traits, demographics, and behavioral patterns. This project showcased my expertise in natural language processing, predictive modeling, and large-scale data analysis.

As a Software Engineer at Pfizer, I played a key role in developing and enhancing applications that empower sales representatives to streamline their workflows and improve customer interactions. My work involved designing, implementing, and maintaining software solutions, leveraging a range of technologies to ensure scalability, efficiency, and integration across systems.

Key Responsibilities & Technologies:

1. Salesforce Development – Built and customized applications to support sales processes, ensuring seamless data management and user experience.
2. MuleSoft Integration – Developed and maintained APIs to facilitate secure and efficient data exchange between Salesforce, AWS, and other enterprise systems.
3. AWS Cloud Services – Utilized AWS for cloud-based solutions, optimizing performance and scalability.
4. Python Scripting – Employed Python for automation, data processing, and specific backend functionalities where needed.
5. Software Testing & System Familiarization – Initially focused on testing to gain a deep understanding of the system before transitioning into development and integration tasks.
6. Agile Methodologies – Worked in an Agile environment, collaborating with cross-functional teams to deliver high-quality software solutions efficiently.

Through my contributions, I helped enhance Pfizer’s sales applications, enabling representatives to work more effectively while ensuring system reliability and performance through continuous improvement and cloud integration.

I earned my Bachelor’s degree in Computer Science from Aristotle University of Thessaloniki, graduating with a GPA of 8.41/10, which is considered quite high. My studies covered key areas such as Software Engineering, Artificial Intelligence, and Data & Web Science. I gained expertise in machine learning, software development, data analysis, and web technologies, preparing me for real-world applications in technology and research.

My thesis focused on developing an online software tool designed to support the evaluation of research output in Higher Education Institutions. The tool facilitates the systematic and efficient collection and analysis of bibliometric indicators at different academic levels, including individual researchers, departments, schools, and institutions.

• Automated retrieval of bibliometric data for individual researchers and academic institutions.
• Calculation of key bibliometric indicators such as citations, H-Index, M-Index, I-10 Index, and publication count.
• Data aggregation for departmental, school, and university-level analysis.
• User-friendly web interface for researchers and administrators.
• Developed using Django (Python) as the backend framework.

This project significantly enhanced my skills in web development, data analysis, and bibliometric methodologies, providing valuable insights into research evaluation.

I served in the Greek Army as a First Executive Secretary and a Post Officer. My role involved handling official correspondence, managing military documents, and overseeing communication logistics. This experience strengthened my organizational, administrative, and leadership skills in a disciplined and high-responsibility environment.

During my internship at APIFON, I worked as a full-stack developer on a project called the Career Day App. The app was built using the Zend framework, a PHP framework. This experience provided me with my first exposure to a corporate environment, where I gained valuable skills in both front-end and back-end development. It was a great introduction to the world of full-stack development and helped me understand how to contribute to larger, team-driven projects in a professional setting.
