Available for contract-based projects related to audio signal processing R&D (consulting, design, implementation).

R&D engineering/consulting in the area of audio signal processing.

• Designed and delivered improvements on existing real-time stereo image expansion and audio levelling technologies on the ADI fixed-point ADAU1701 DSP. • Developed and tested, as part of a 2-person team, a VST-plugin version of one of the company's audio products. • Carried out research and presented results on music audio enhancement. • Instrumental in liaising with contractors, for the design, development and testing of audio software. • Familiarisation with the Linux LADSPA plugin standard.

• Designed, implemented and evaluated in MATLAB a novel system that carries out sound morphing between any combination of two sounds. The system is scheduled to be integrated in a future version of the Alchemy synthesizer plugin. • Implemented and tested 4 audio spectral manipulation effects in MATLAB, to be included in the next major version of the Alchemy synthesizer plugin. The project was carried out through concise communication and proactive collaboration with my manager.

Designed from scratch, co-ordinated and taught in 24 lab sessions (62 hours in total), as well as contributing in the updating of the lab scripts. The sessions were related with the modules: Audio Source Coding, Audio Processing Techniques and Environments, Digital Sequences, Correlation and Linear Systems and Digital Filters. The modules were part of undergraduate and postgraduate courses taught at the Department of Electronics.

Everyday face-to-face interaction with the customers, managing the book stock, liaising with the other departments of the shop and ordering new titles.

• Responsible for operating and maintaining digital and analogue communication systems of critical importance. • Researched and appropriately disseminated news material containing information concerning the Greek Air Force.

Collaboratively developed, installed and maintained the contract customer’s IT and telecommunications infrastructure. Close, everyday contact with the customer, including providing face-to-face training to individual customers on the use of their IT equipment.
