Summary of Innovations assisting the growth of the Greek Internet
1995 – Established the first and most frequent news service (updates every half an hour) for the benefit of the Greek diaspora via SKAI Radio (Charitable work, done for free, as I approached the radio station and asked them to implement it so that my Greek friends in the UK and the USA can read the news)
1995 – First Real Media Streaming service in Greece (for Olympiakos.gr – I run at the time with friends)
1996 – First electronic newsletter and page personalisation from a Greek newspaper (naftemproriki.gr)
1996 – First ever Macromedia Director and Flash technology deployment in Greece.
1996 – The first Greek on-line record store in the best address of the internet (music.gr)
1996 – Contributor and equity holder in the first web-based virtual community on the web (the Canadian suite 101)
1997 – Involved with the first windows based editorial-content management system in Greece, tightly integrated with “the Internet” via IBM’s Lotus Notes (for Lambrakis Press).

Summary of Innovations assisting the growth of the Greek Internet
1998 – Part of the team that created the first website of Greek National Television (ERT).
1999 – The first article published in the Greek press about the many-to-many nature of the Internet with RAND’s James Dewar.
(break in 1999-2000 studying New Media at the City University London; on scholarship via “The friends of the Music Society” presided by the late Christos Lambrakis.)
2000 – Introduction of the first automatic translation to/from Greek/English/French of web pages and/or selected text with the use of Systran translation technology, so that more Greeks (who didn’t know foreign languages can find useful the Internet).
2000- First on-demand music service in the Greek internet (with Everstream).
2001 – First push chat\customer support in Greece (i.e. when a visitor could be proactively approached for support (service dropped because people were getting scared))
2001 – Part of the Global team of Software engineers that coded the first .NET based forum application for Microsoft (volunteer work in lieu of learning .NET and shaping its future development/features).
2003 – Introduction in Greece of the first forum in a Greek company where the “demanding customers” could discuss openly and freely their opinions (was for the Olympiacos Athletic Club).
Summary of Innovations assisting the growth of the Greek Internet
2004 – Introduction in Greece of the first Google Ads in order to help smaller publishers to make money from their content. Trial was performed at www.Olympiacos.org where we helped Google debug its engine to support Greek and UTF-encoded text.
2005 - First deployment of Microsoft CRM for a greek NGO (Olympiacos); that became a Microsoft EMEA case study (see other presentation in my slideshare profile)
2007 - Established metadata with the encouragement and a loan from my former employer.
What “metadata” are, was unknown for most, though metadata became a household term in 2013.
Started with 5 people and did a turn-over of 300,000 on its first year - Grew to 18 people (and an 850,000 turnover on tis second year) and Reached nearly 30 people (and was looking forward to a multimillion turn over) was “killed” by such an event.
Indicative innovation. Our CMS, metaCMS succeeded in replacing one of the most expensive CMS on the market (Vignette) for Eleutheros Typos at a fraction of the cost, offering equal or better functionality. Vignette; it usually costs 300,000 for the setup and the first year and 150,000 annual maintenance fee. We replaced Vignette in one of Greece’s leading newspapers (Eleutheros Typos) at a cost of 30,000.
2009 - Undertook the website development of Greece’s busiest web-sites Zougla.gr that was suffering reliability issues.

Architecture
Treating news-stories as products for sale (with add-ons on various platforms) and retail products as rich-media objects (to differentiate them from competition)
Separating content from presentation Web authors\web developers can operate independently from designers.
The content can be transferred into different formats.
The content can be reused.
The complete redesign of the experience it is a matter of content managers and designer – no developers involved.

Architectural Design Fundamental Units Templates
The template has available regions-positions for the placement of specific controls with fixed or linked (with other control) dynamic content
Business Objects (content)Support for a series of content ontologies such as Articles, Files, Events, Banners whereas the open and modular architecture of the platform enables the creation of unlimited number of ontologies based on the requirement of the clients. Object update (debugging) can propagate to all clients.

Sample code…
The C# sample code provided from the stock market module of metaCMS is indicative of the code written\supervised.
The _css, _js and _gfx directories provided by one of the Sklavenitis sites are indicative of the quality of the front-end code – part of it was part the given questionnaire (e.g. sprites, see wood_spirte.jpg).
Data Visualisation
The task at hand: Quantify the impact of the assets of one of Greece’s wealthiest individuals – personal property estimated to over $5 billion, map all the relations of his holdings in “one page”!
The solution: Collect data using WSS (the freeware SharePoint) through an InfoPath form. The XML feeds an SQL server (thus avoiding duplicate entries)
Following data cleansing a flat array was given fed into a Flash application (the demo you will see contains all the visual data in 66kb)
Year of development: 2005
