I’ve got Technology, Data, and Media. Here’s how i use them.

I started as a columnist for ZDNet’s Big on Data in August 2016, bringing years of writing experience to the team.
I have been expanding the column’s traditional focus on analytics, business intelligence and database industry news to include innovation in areas like Machine Learning, AI and Blockchain, data analysis of news stories and original research.
By the end of January 2017, i had set a new record for column monthly readership, exceeding column average by 300%.


I have been doing analyst work for years, and got my break in the mainstream sort of serendipitously.
After deciding to let go of my first startup and while looking for my next project, i got in touch with Gigaom.
Gigaom was expanding in Europe and looking for experienced analysts, i joined them, and the rest is history.
The first report to highlight the importance of agility and cloud features for BI, preceeding Gartner’s adoption by 8 full months.
The project was initiated independently, capitalizing on insights gained while mapping the competitive landscape my startup.
The report was endorsed and marketed by Gigaom and sponsored by Tableau.
Gigaom-commissioned research aiming to map the Hadoop security landscape.
Time to market, thoroughness and conciseness were the requirements for providing a usable and to the point overview ASAP, in order to respond to immediate customer demand and market pressure.
The report was published within 2 weeks of commission and covered the entire Hadoop security landscape in under 10 pages.
Developer Economics is the leading research program on mobile, desktop, IoT, and cloud developers.
The 2016 Q1 edition tracked experiences from more than 21,000 developers in over 150 countries and across platforms, revenues, apps, languages, tools, APIs and segments.
Working with VisionMobile we analyzed results, highlighted trends and provided insights on how those will change the software landscape.
I help organizations get the information, educated opinions and hands-on help they need to tackle a wide array of issues.
From strategic to mundane, from dealing with land corruption in Africa and navigating market opportunities to resolving server issues.
No matter what the issue is, delivering the best possible result in the given timeframe is my mission.
Transparency International has been working on fighting corruption in sub Saharan Africa, aiming to secure land rights.
In order to face challenges related to the complex and fragmented administrative, legislative and technological landscape in the region, TI commissioned research to develop a conceptual model of information to document the current situation and pave the way forward.
Our methodology, models and proof of concept are being implemented and published in the World Bank Land and Poverty conference.
This stealth startup wanted to re-evaluate their domain (Proximity-based apps) to determine whether a pivot would be in order.
They commissioned research and analysis on the technical and business landscape to guide their evaluation.
The assignment was completed in 1 week, delivering a report to document findings in addition to consultation with company executives.
Vodafone Greece was facing issues with one of their application servers, causing performance degradation and downtime.
Commissioned for 1 day to propose solutions, i conducted stress tests, investigated and documented what-if scenarios.
A report was delivered to document findings and server performance was optimized based on those.
I believe in building models that are as simple as possible, but not simpler, and have been doing that for years.
Whatever the reason for approaching a domain, a model that captures it in an accurate and flexible way is essential.
Formalism, models, meta-models and tools are useful, but it all comes down to having the right model for the task at hand.
Integrating Energy Management Systems can drive innovation and provide added value services for citizens and public authorities.
Working with domain experts, we surveyed the field, devised a methodology and created a Common Information Model to unify disparate Energy Management Systems, based on profiling and extending the IEC 61970 standard.
The model is used in a number of applications and has been published as a result of the BESOS EU Research Project.
Applying collaborative decision making on a wide scale in the real world requires interoperability and intelligence.
Towards this end we introduced an ontology and algorithms building on the state of the art in Problem Modelling, Idea Management and Collective Decision Making.
This model powers Local Government and Professional Associations and was featured in the World Wide Web conference in 2012.
Digital Transformation in the Army means empowering the chain of command and control to operate more efficiently.
Data pertaining to the entire spectre of military operations was collected, analyzed and integrated in a data warehouse.
The warehouse provided an overview of strategic and tactical data via a secure dedicated access point
I have led collective efforts of all sizes and shapes through the years, from enterprise-wide initiatives to ad-hoc hackathon groups.
I stand for leading by example, inspiring and getting the most out of any person and situation. It works for everyone and it gets results.
If building a dream team is an option, great, if not, it’s still all about empowering people to be the best version of themselves.
What if we could use open data and crowdsourcing to deal with climate change? This what-if idea got far.
From getting one person to join in a hackathon to leading an ad-hoc group of 12 to work in one room for 48 hours for the NASA Space Apps Challenge is quite a distance.
Our solution was nominated for People’s Choice Award, was featured in mainstream news, and qualified for an EU innovation grant.
Turbulent times require clear steering, and that i provided managing the EAI Department for this major solution provider.
The department was reorganized, new recruits were hired and trained, and our key project was delivered within time and budget.
This enabled the company to successfully handle a changing market with threatening competition at a time of crisis.
Leading a team of 20, from consultants and business users to developers and interns, for one of Europe’s biggest telcos is hard.
Evangelizing, teaching and applying cutting-edge technology to deliver the organization’s core business platform in an extremely limited timeframe with that team is no easy feat either.
It worked, and delivered results and established a trust relationship that resulted in a continuous flow of follow-up projects.
I help organizations develop products that get market share and gain distinctions.
I can define product scope, features, and architecture, and research, select or develop solutions for the entire product stack.
Equally important however, i can work in cross-functional teams to shape, steer, manage and market products.

I have a track record in taking technology out of the lab and using it in the real world.
It takes technical ability, business acumen and communication skills to identify opportunities and gain momentum in an organization.
It’s a huge challenge, but it pays off handsomely when done right.
As the lead architect in a key project in one of Europe’s biggest telcos i pioneered principles and technologies in use there since 2002
Business Process Management modeling and implementation, Enterprise Application Integration, Object-Oriented design and modular, Component-based architecture, Message Queues and Application Servers.
Using them in production before anyone else generated added value that put the organization way ahead of the competition.
As the R&D Director of an SME for ~4 years, i championed a number of technologies and approaches that took it to the next level.
Research on and integration of semantic technologies in core products, introduction and operationalization of Agile Development, DevOps, Content & Knowledge Management, and the release of internal R&D projects via Open Source licences
All that helped put IMC Technologies on the map internationally as a leader in its market.
As an engineer my first big assignment was an understaffed, behind schedule project, with broken communication and chaotic design.
I re-designed the architecture from scratch, throwing away antiquated and inefficient solutions and replacing them with state of the art. I championed a solution featuring XML over HTTP and a Web Client back in 1999, before Web Services or Web Apps were a thing.
As a result, the project made its goals and was adopted as a best practice throughout the organization.
I am driven by passion for research that makes a difference in the real world.
My research spans the fields of Distributed Systems, Semantic Technologies and Participatory Decision Making.
Always happy to set sail for new research adventures, as long as they’re meaningful.
eDialogos is a platform for participatory decision making that served as an umbrella project spawning a number of R&D initiatives.
Bringing together years of R&D experience, an interdisciplinary methodological approach and solid engineering, eDialogos was the opus magnum of IMC Technologies.
Our work led to a number of research publications and a nomination for the 2009 European eGovernment Awards.
