My name is Konstantinos (or Kostis) Leledakis and I am a Greek with teaching experience on physics math and programming. I use LaTeX for many years and I have completed many jobs on LaTeX. I use tikz package for figures and effects. During my studies I was a professor's assistant in programming courses for 4 different professors. Thus, I can create some desktop applications (more Qt/C++ and C or Python) if someone ask for one and also this is very useful in my LaTeX jobs because I have automated some LaTeX tasks such as creating simple tables or transform Word like references to LaTeX bib file. You can find work of mine in LaTeX and a CV in my portfolio.

    “I requested Konstantinos (koleygr) to replicate 7 images I sent him in TikZ (i.e. reproducing the images by using LaTeX code). Not only were the images he produced *better* than the original ones that I sent him, he was also very accomodating to any requests I had in changing or altering the images to meet my needs. Furthermore, as I mentioned this project was urgent, he worked extremely hard and finished this project in half the time that I expected. He was readily available to talk over chat, and frequently sent me status updates to make sure we were on the same page in terms of what the deliverables should look like. Konstantinos was very professional throughout and I would absolutely not hesitate to use his services again for any LaTeX tasks I have. 5 stars well deserved! :)”
