I am an information & communication systems engineer with nearly two decades of experience in the industry, in particular on system architecture and hardware / software integration for a variety of successful products in both consumer and infrastructure sectors. I hold postgraduate degrees in Digital Telecommunications, Electrical Engineering, from the University of British Columbia, Vancouver, Canada.
Between May 2015 and March 2017 I was Chief Architect and acting VP Engineering at mimik Technology Inc., responsible for leading an agile engineering team in a pre-revenue startup environment, providing architectural direction for products and solutions in the company road-map, developing success metrics and implementation plans. Since joining I was instrumental in revamping software development life-cycle management tools and processes, contributing to the transformation of an R&D culture into a product and market driven one. As a senior member of the management team, I regularly communicated company technology strategy to employees, partners, customers and investors.
Between December 2010 and March 2015 I was with the technical department of Thenamaris Inc., a top-tier ships-management company, developing and leading the electrical engineering group, supporting superintendent engineers, fleet electricians (in the order of one hundred individuals) and the newbuildings team in all things related to electronic automation, onboard ICT, telecommunications, radio navigation and telemetry for energy optimization. My responsibilities also included overseeing maintenance, as well as planning, management and execution of related development and infrastructure projects with average annual budgets of 1-2M USD.
Between November 2003 and April 2015, I served the European Commission (ICT research area), as evaluator and rapporteur during selection of projects for funding, as well as reviewer for monitoring execution of funded projects, under the EU 6th, 7th Framework (FP6, FP7) and Horizon 2020 Programs. Over the course of nearly twelve years, I took part in a total of ten week-long evaluation sessions and co-monitored successful execution of fourteen projects with budgets totalling in excess of 76M EUR and typical life-cycles of 2-4 years each.
Between September 2006 and July 2010 I was involved with system engineering and development of wireless RFICs, for broadband (MIMO) and microwave back-haul (SISO) systems for Theta Microelectronics Inc., an RFIC design services & IP provider, as Systems & Applications Manager. This resulted in two successful chips, one for wireless HDTV transmission in the home under the WHDI standard, and one for fully integrated microwave-link transceivers. During these years I also served as company-customer interface, managing interaction and chairing face-to-face meetings.
My involvement between 1998 and 2006 had been in state of the art wireless topics such as WiFi (IEEE 802.11 wireless LAN), WiMax (IEEE 802.16 wireless MAN) and BlueTooth (IEEE 802.15 wireless PAN), both as senior design engineer and as group manager, in the Multimedia & Communications branch of ATMEL Corp..
Even though I do not hold a major in Computer Science, my involvement and in-depth experience with computing and networking reaches back to the mid 90's and the infancy of the Internet and the World Wide Web. My experience with operating systems spans nearly three decades, beginning with Exec 8 on a Sperry UNIVAC 1100 series mainframe and UNIX on a Perkin Elmer 3200 series minicomputer, encompassing a multitude of computing appliances and embedded varieties for special-purpose hardware. Being an earnest supporter of the Open Source movement since its inception, I have been contributing code and advocating software freedom for nearly 25 years.
Free/Libre/Open Source Software (FLOSS)
I have been active in the Open Source movement since the end of 1990, contributing to GNU/Linux - its flag-ship operating system - and to core components such as the X-Windows system (or X11) pioneered by MIT, as well as writing stand-alone applications and utilities for solving problems ranging from generation of publication-quality scientific and 3-D visualization plots, to dial-up Internet connection control and management of multiple ISP accounts and associated call charges.
X-ISP is a visual, X11/XForms based, user-friendly interface to pppd/chat, i.e. a dialup TCP/IP tool with an X11 interface. It is also a small ISP and phone company (PTT) database manager, and a dialup costs and usage logging/statistics tool. It provides maximum feedback from dialing and login phases on a message browser, versatility in interrupting a call in progress, a manual login terminal window, as well as call-back and per-ISP DNS selection capabilities. While practically obsolete today in a broadband-access dominated world, X-ISP had been featured in two Linux Journal, articles, in the December 1998 and December 1999 issues. For more details go to the official X-ISP site.
xmailbox started out as an enhancement to xbiff, the traditional visual mail-checking application included with even the earliest versions of the X-Windows system. In an early version it was included in the contributed applications and utilities of the X11R6 official distribution. In the form of its last release it supports animation and a multitude of sound subsystems such as the NCD NAS server, the rplay sound server, the standard audio driver for SUN Sparc computers, Linux and FreeBSD audio drivers, and external sound players. xmailbox had been featured in the October 1995 issue of the Linux Gazette.
Xaw3D is a three-dimensional version of Xaw, the X11 widgets from MIT project Athena. A drop-in replacement in most architectures supporting shared libraries, it adds Motif® look-and-feel to the otherwise visually unappealing Xaw library. Having contributed extensively with functional and visual enhancements to the original code, I have been listed in Xaw3D's official group of authors.
My involvement with Unix & X11 since 1990 and Linux since 1992, and in particular my contribution to the the X-Windows system, had been acknowledged with a complimentary developer's copy of the SuSE (now openSuSE) Linux distribution each time a new version was released, between November 1995 and March 2011.
Between 1991 and mid 1994 I served as President of the Amateur Radio Society (ARS) at the University of British Columbia. The UBC ARS is a non-profit, student organization governed by UBC's Alma Mater Society, with a mission to divulge Amateur Radio as a hobby to students, faculty, staff and the community. During these four years we greatly increased student membership, successfully completed ambitious infrastructure projects (radio repeaters in the 144/440 MHz bands, auto-tracking 144/440 MHz satellite station, experimental high-speed wireless digital links in the 220/440 MHz bands), and published two preparatory course books on obtaining an Amateur Radio Operator certificate, while augmenting the already very successful weekend courses offered for those planning to take certification exams. The two text-books ("Amateur Radio Basic Qualification Manual" & "Amateur Radio Advanced Qualification Manual" - of which I am a co-author) together with the weekend courses were, for many years, the Society's main source of income.
I have been awarded Advanced Theory and Morse Code certificates in Canada, where I am a licensed amateur radio operator and hold the call-sign VE7HDB. Since October 2010 I have also been assigned the Greek reciprocal call-sign SV0XCB.
