Mostly interested and motivated in parallel computing ( OpenCL/CUDA/Multithreading, HPC) on concepts about DSP, AI, image processing, machine learning, cryptography. I have experience using libraries targeted for fast GPU development like Cublas/CuFFT/Thrust. Currently interested in gaining experience in webAPI development (mostly with Python tools) Other objective is to expand my experience in other software development areas. Open to the opportunity of contributing to interesting open-source projects. In general, I enjoy the process of analyzing a complex algorithm and transforming it to efficient code

    “The project was originally estimated by the Athanasios to take 3-4 days after he fully reviewed all the requirements and websites involved. It took him over one month to complete. I was not happy with the lack of communication, the lack of timeliness, and the fact that he asked me for more money at the very end after it took a month for him to finally get it all completed. After he finished the work, he only then let me know that he wasn't as familiar with this type of work as his proposal made it seem. There were issues with the way the work was delivered, but not big enough nor worth me spending more time getting it fixed. He is a good guy, just not a fit for my project.”
