- Principal Architect (Dec 2011 – present) – Microsoft Corporation
Thought/design/architecture/execution leadership and development work on key projects: Cortana cloud-based personal digital assistant, large-scale graph store, reactive information processing at scale, conversational system. I got awarded my third “Gold Star”, which is Microsoft’s recognition for high achievement and quality of work.
- Principal Developer (Dec. 2009 – Dec. 2011) – Microsoft Corporation
I worked on Big Data/Cloud Computing technologies as a developer/architect. I was responsible for the design and implementation of technologies related to large-scale distributed computation (e.g. map-reduce), NoSQL stores, and cloud services. I got awarded with my second “Gold Star” and ranked as a “top performer”.
- Principal Developer (Dec. 2008 – 2009) – Microsoft Corporation
I designed and prototyped Semantic search infrastructure for Bing.
- Architect (Nov. 2006 – Nov 2008) – Microsoft Corporation
I joined Microsoft’s Technical Computing Group, reporting to Corporate Vice President Tony Hey, in order to work on technologies, services, and tools that help scientists and researchers be more productive and efficient. I was awarded with a “Gold Star” for my work. Highlights:
- Architected, prototyped, and lead the team that implemented Zentity, a SQL Server 2008/Entity Framework-based solution for a semantic computing platform to store and manage the research out-put of an organization; lead the team of 20 offshore engineers to execute on the implementation;
- Technical lead of External Research’s “Cloud Computing for Science” vision, implementation, and deployment.
- Program management of the Microsoft-Intel joined sponsorship of the Universal Parallel Computing Research Centers;
- Design and development of various plugins for Office to be used for research (now released as open source);
- Interactions with leading scientists worldwide;
- Whitepapers about the future of computing for science, social networking, and semantics that reached Bill Gates who positively commented on them.
- Program Manager (2005 – Oct. 2006) – Microsoft Corporation
I joined Microsoft’s Connected Systems Division architecture team to investigate possible directions for the next generation development platform. While working for Brad Lovering’s team of architects, I gained valuable experience on how Microsoft technologies move from ideas and prototypes to products. I was also given the chance to own two Web Services spec-ifications and lead the necessary technical work and negotiations with IBM.
- Principal Research Associate (2003 – 2005) – School of Computing Science, University of Newcastle
My research while at the University of Newcastle focused in the areas of service-oriented, distributed, high-performance computing with an emphasis on Internet-scale architectures. The focal point of my investigations was the articulation of architectural principles for Internet-scale computing and how they could be applied us-ing Web Services technologies.
- Chief Software Architect (2003 – 2005) – North-East Regional e-Science Centre (NEReSC), University of Newcastle
In addition to being a principal research associate, I was also NEReSC’s chief software architect. NEReSC was involved in a large number of high-profile projects in the areas of data-intensive computing, bioinformatics, virtual organizations, and high-performance, distributed computing. My architectural duties included involve-ment with all the centre’s research projects during their design and architecture phases, setting the direction in terms of the set of technologies used for all implementations, and providing advice on Web and Grid stand-ards and specifications.
- Private (2001 – 2002) – Greek army
Fulfillment of the military service duty (awarded a distinction of honor). Although my duties in the Greek army were not related to computing science, I experienced the disciplined life of an army and learned how to work within a team.
- Senior Software Engineer (2001) – Hewlett Packard
Co-investigator in an R&D team in the area of Transactions for Web Services. Principal role in the research, design, and implementation of the XML Transaction Service (XTS) the prototype on which the HP-WTS 1.0 prod-uct was based.
- Research Associate (2000 – 2001) – Dep. of Computing
Science, University of Newcastle Post-doctoral research in the area of parallel, high-performance computing using clusters of workstations and object-oriented, visual programming languages for parallel computing.
- Doctor of Philosophy in Computing Science (1996 – 2000) – University of Newcastle upon Tyne
Title of PhD thesis: Run-time Support for Parallel Object-Oriented Computing.
The research work involved the implementation of an all in software object-based DSM system, novel object caching techniques for distributed systems, and a new lazy task creation technique. The thesis dealt with de-sign and implementation issues in the areas of load-balancing, high-speed communications, and clustering.
- Master of Science in Computing Software and Systems Design (1995 – 1996) – University of Newcastle upon Tyne
Achieved highest marks in year. My dissertation work was in the area of run time support for mobile agents.
- Bachelor of Science in Information Technology (1991 – 1995) – Dep. of Software Engineering, TEI of Thessaloniki, Thessaloniki, Greece
Second in class, final year. My final-year project on DNS and sendmail was awarded with distinction.
