Senior Software Engineer
Centre for Research and Technology Hellas (CERTH)•  September 2013 - Present
As a senior software engineer at CERTH, I increased the average number of active projects per year (both from the industry and R&D) in my group from 3 in 2013 to 8 in 2022 by delivering high quality software and innovative research results. This resulted in a high increase in my group’s budget from less than 1M Euros in 2013 to more than 2.5M in 2022. In addition, as a team lead, I guided and mentored teams of junior and mid senior software engineers, machine learning engineers and data scientists. During my years in CERTH, our group has grown from 3 people in 2013 to 25 in 2022. Moreover, I boosted the productivity of my teams of software engineers by 100% as measured by relevant code productivity indicators (e.g., source lines of code and average number of code commits per day) by promoting the use of formal software development processes. Finally, along my teams of data scientists, I have published 25 papers in both peer-reviewed journals and conferences.
Senior Software Engineer
MaaS Alliance•  September 2020 - December 2021
I participated as a technical expert in the Technology & Standards Sub-Working Groups of the Mobility as a Service (MaaS) Alliance. The Mobility as a Service (MaaS) Alliance is a public-private partnership creating the foundations for a common approach to MaaS, unlocking the economies of scale needed for successful implementation and take-up of MaaS in Europe and beyond. The main goal is to facilitate a single, open market and full deployment of MaaS services. As a member of the Architecture & APIs subgroup and the Data Modelling subgroup, I have been involved in the activities of designing the architecture of the software infrastructure (e.g., RESTful APIs, data models, storage systems and integration pipelines) that will support the development of next generation MaaS systems.
