    I am a Masters in Computer Science, graduated from the University of Crete. My master's thesis topic is about parameterisable automated GUI generation from data structures using a dynamic language. My interests involve computational complexity, algorithms and algorithmic solutions which use high-level recomposition or problem reduction, graphic algorithms, low-level 3D processing, cryptography, theoretical development tools, theoretical studying and analysis of languages, as well as languages themselves, among many, many others. I have worked with all traditional and mainstream "system" languages (c, c++, java, c#), as well as "scripting" (ruby, Delta, javascript), and (even) functional languages (haskel, scala). I also have worked in many different fields of applications, ranging from a toy postscript resterizer, a couple of CPU simulators, byte-code compilers and virtual machines, interpreters, project-description translators (and therefor toy build-systems), tons of linux junior (and juvenile) administration and scripting, web-development (mainly in PHP and ruby), 2d games, 3d graphics (such as surface generation, texture mapping, lighting), peer-to-peer experimentation (a "p3p" chat client), cryptography, and probably even more that I cannot recall any more. I enjoy learning and using solely the latest (bleeding edge) technologies and methodologies. I particularly enjoy a lot researching common wisdom about specific topics, I enjoy splitting problems into topics about which there is wisdom to be found, and finally wishing to create new wisdom through problems that truly hit new frontiers. My ideal projects involve bits and pieces of such technological and scientific challenges, and are (ideally) about something "cool and interesting". I enjoy a lot talking out and figuring out common ground and specific arrangements which make everyone happy. Apart from computers, I am also a dancer, a mover, a thinker, a musician, a healer and a researcher. Feel free to contact me if you have specific questions, if you feel you need to validate any of my claims, you have an objection about what I ask in exchange for work, or simply to have a chat and get to know me.  less

    Most recently, my projects have focused on the development of scalable BI/Analytics/Reporting products in the heathcare domain, leveraging BI platforms such as GoodData, Pentaho/Mondrian/Kettle, and JasperServer. These solutions were built upon relational databases including PostgreSQL and columnar databases including Vertica and InfiniDB. In addition, I have additional experience using map-reduce tools such as Hadoop to perform analysis, data cleanup and ETL, as well as graph analysis and visualization using Gephi.  less

    I'm an expert in Clojure and Scala functional programming, and scalable systems. My greater background is in Java development and I have sufficient knowledge of Javascript and web front end programming to be productive. I'm well versed in all stages of application development, from the early planning and pre-planning days on to post release. I'm a big fan of agile and the devops movement, and I love to work in great cross-discipline teams. I've been remote contracting for over a year now, I'm a great communicator and familiar with a wide range of remote collaboration tools. Before this I was an employee at Mind Candy, an entertainment startup based in London, where I was working on Scala and Java development, at first on the Moshi Monsters game and then later leading back end development on the Moshling Rescue mobile and Facebook game. Both titles required efficient, well designed code able to scale to many concurrent users and easily handle times of peak load. Throughout my time at Mind Candy I also acted as a mentor to other members of staff that were coming newly to Scala from a Java background, helping to ease their transition and become fully adept at writing idiomatic functional Scala code. As well as development I've been involved heavily in "developer multiplier" tasks, through such things as adding continuous integration servers, building a deployment pipeline, adding code metrics and other, more manual, things such as code reviews. I'm a big fan of sharing information, presenting what I'm working on and interested in and hearing about the same from others. I can help you with development, system design, choosing a database (SQL and NoSQL) and designing data types, scaling systems, migrating from Java to Clojure or Scala, improving your tooling and build chain, and more. I'm available for long term engagement, or for shorter projects.

    I'm a Software Engineer with extensive experience managing all aspects of the software development lifecycle in different business types, such as: health, insurance, sales, marketing and internet business. I also have planned and developed IT Infrastructure projects. After 8+ years of experience, I feel that my professional expectations are more related with technical aspects. In programming I always try to write simple, readable, efficient, consistent and maintainable code since I believe that here reside the true return of investment. I enjoy greatly working in "self organizing teams". In my free time I like reading books or watching movies with my wife.
