Hello. I am Apostolos Kritikos. A Critical Engineer — specialized in Open Source Software — and Researcher “made in Greece”. I love coffee, listening to music / podcasts, reading books / comics and doing the lindy hop (swing dancing).

Open Source Software

The first time I heard about Open Source Software (OSS) was in 2001. But I really started getting a grasp of its true potential and actively working with it in 2005, during the 3rd year of my bachelor studies in the School of Informatics, Aristotle University of Thessaloniki. Nowadays OSS is considered mainstream globally and I couldn’t be more happy. It has been the running force of all my professional endeavors, has fueled my academic research and makes my digital life easier every day.


I started working as a software / web developer circa 2006. Back then developers were considered swiss knives so during the early years of my career I worked on IT support, networks, software / web development and research oriented ICT projects. It was amazing and I learnt tons of stuff about the profession.

In 2011 I founded a two-person software house with the aim of getting bigger contracts from being a solopreneur. In 2014 our little software house evolved to Social Mind, a web applications and digital marketing agency that is growing ever since. This journey came to end (for me, the company continues to grow) during 2022 when I exited Social Mind’s board of shareholders. I am currently serving as an Engineering Team Lead at Toggl, helping to provide the best time tracking and project management experience online. If you or your team are interested in high quality time tracking, project planning or hiring, I highly recommend that you give Toggl a try!


After getting my Bachelor’s degree in Informatics, I completed a Master’s degree in Informational Systems. Today I am doing research on a PhD level with the School of Informatics, Aristotle University of Thessaloniki in the fields of Open Source Software Engineering and Software Resilience. 

Academic Research has been professionally enhancing me with extremely useful skills for the last decade. Analytical thinking, out of the box design, agile methodologies, fact checking mechanisms, test first design approaches are only a select few.
