Hello


This is my personal website where you can find out about my professional work, all my interests and hobbies, as well as my little corner in the web decorated by my thoughts.

I've worked as a researcher for more than 10 years in the field of software optimisations for embedded systems. Currently, I have started a development company called CodeHeaven Studios with my wife.

I believe in a world where everyone is who they are, without shame or regret, respectful of each others' choices.

Thank you,
Chris Baloukas

Academic Career


The past few years I worked as a research associate for the Microprocessors and Digital Systems Lab, at National Technical University of Greece.

I participated in several European (FP7 / Horizon2020) and Greek National projects. I led one of them and was a main contributor in many of the rest. During these projects, I've written or oversaw various deliverables and dissemination activities. I was actively involved in both the technical and managerial aspects.

My research interests include software optimisations for resource constrained systems like embedded devices or FPGAs. In particular, I have experience with dynamic memory optimisations and dynamic data structures.

Development


Early Efforts

I've started my development efforts as a teenager with simple HTML websites and later Visual Basic in Microsoft's Visual Studio. While I was studying Electrical and Computer Engineering, I learned several languages like C, C++, PHP, FORTRAN, VHDL.

Designing hardware with VHDL was really enjoyable and I could just as easily turn towards development for hardware components, but I choose to work on the software side.

Academic Years

For my diploma thesis I dived deeply into C++ leveraging templates and polymorphism to create a library of data type components that can be combined into data structures. Based on the needs of the application the original data structures could be exchanged with data structures from our library, only using the absolute necessary components for the desired functionality. This way, the memory requirements and performance of the data structures could be improved, sometimes by a lot.

Recent Projects

The last few years I got into mobile development, especially apple platforms. I loved working with objective-C and later swift. I found them very easy to work with, letting you feel creative, while maintaining a high performance level.

Recently, I created a development company with my wife, called CodeHeaven Studios, specialising in iOS and web/e-commerce development. Our first app, EarTrain is a music app for improving your perfect pitch. To find more about our development work please visit our company's website using the link below.
