My name is Ioannis Kalliantzis and 23 years ago I was born in Thessaloniki, Greece. I am a graduate of the Computer Science department of the Aristotle University, the largest university of my country. I am also pursuing my MSc on the same department having a Major on Big Data management and Machine Learning. Being a part of the Computer Science community was my dream since I was a child. I love to create things, to start from nothing and to create something beautiful and useful. In this carreer you have the chance to create a whole new world with just your fingers and a laptop!
For the last couple years, I am working at FoodTec Solutions Inc. For the first few months as a Quality Assurance engineer in order to familiarize myself with the company's platform and then I made the transition to the development team working as a full-stack developer. Working at FoodTec Solutions Inc was a great opportunity for me, since I was given the chance to work in one of the largest software development companies in my city before I even graduate from college.

FoodTec Solutions Inc• April 2016 - until now
At my first steps as a developer I worked on the maintenance of a Java desktop application. It was an Inventory tracking app used by large chains of restaurants, built with Swing for the UI that was also able to communicate with third-party applications by exchanging csv files through an SFTP server. Simultaneously, I also worked as a Full-stack Web Developer, enhancing the company's webapps back-end part, written in Java using the Spring framework, and the front-end part building webapps on Angular 4.
I also worked on company's Reporting platform where I was responsible for creating reports using historical and real-time data. The data was retrieved from an Oracle SQL database and the logic behind the reports was written in Java.
All these tasks, gave me the necessary experience and exposed me to a lot of aspects of Software Development. Also, working on the Reporting platform, made me taste the job of a Data Scientist and I loved it.
FoodTec Solutions Inc• April 2016 - November 2016
Before I even graduate from university, FoodTec Solutions Inc, gave me the chance to work on the subject I was studying. Being arround experienced software developers, was a great chance to help me grow.
As a Quality Assurance Engineer, I worked along with the developers in order to test the new enhancements introduced to the project. I was also responsible for troubleshooting issues reported from our customers, for witting test cases and writting internal and external documentations. I was also lead in the QA team of a cross-platform mobile app that started to be developed about the same time I joined the company.
I then made the transition to the company's development team. Having mastered the way the system should operate, having worked with REST APIs, FTP and SFTP servers along with having to "dive" every once in a while into the code in order to troubleshoot reported issues, made me feel confident enough to start my development journey
Lambros Bakery P.C.• February 2014 - March 2016
Working as a General Manager at Lambros Bakery P.C., being the one that was responsible for the proper operation of all the stores that the company possessed, I learned to be responsible and able to guide a group of people in order to achieve the company' s goals. I left this job in order to pursue my dream to work as a software developer.
Lambros Bakery P.C.• September 2013 - January 2014
I started working at Lambros Bakery P.C. while being an undergrad in order to earn my first salaries. Unexpectedly, after a few months I was promoted from a seller to Store manager and then to General Manager, having a great chance to learn how companies work and to acquire leading abilities.
Computer Science Department, Aristotle University of Thessaloniki• October 2017 - now
I am currently pursuing my Masters degree on Knowledge, Data and Software technologies. Specifically, the courses that I am attending at this semester are the following:
Computer Science Department, Aristotle University of Thessaloniki• October 2012 - September 2016
I graduated from CS department of AUTh after 4 years (which was the program's duration) with a grade of 8.1 out of 10. Four years ago I chose this specific department of Aristotle University because I love to create useful and innovative staff as much as I love being near to anything with "computer" keyword in its description.
After graduating from this school and along with a lot of after-school studying I am in a position of having worked with programming languages like C, C++, Java, PHP, Python and JavaScript. I have also worked with databases (Oracle SQL and MongoDB) and with other technologies like HTML5, CSS, AngularJS, NodeJS and ExpressJS frameworks. All of these skills combined with a deep knowledge in Mathematics (Discrete Mathematics, Calculus, Statistics and Applied mathematics in Computer Science), Algorithms and Data structures create a complete profile of a Software Developer.
Bellow you can see some skills of me that I have acquired the past few years either from my school or from my work.
