Ivan Kalafatic

Passionate electrical engineer & developer


Hi, I am passionate electrical engineer (MSc), who loves to deal with micro controllers, PLC's and has a lot of experience from field of repairing various electrical equipment (both home and industrial), as well designing both analog and digital circuits, programming Atmel-AVR micro controllers (Bascom, AVR-C, Arduino programming languages). Also I have experience in fields of Industrial control and control technologies. I have about 5 years of experience in using Cadsoft Eagle package (both schematic and layout), and 1 year of experience in using Altium designer. Had several projects where I used various GPS/GSM/GPRS/Bluetooth/Accelerometer modules. My most complex project was to design and program control electronics for lifting stations for sewage, which consisted of AVR MCU, 4x 15kW pumps, matching system for reactive energy compensation and web site for collecting and reporting system data to supervisor using GPRS Internet access. I consider myself as versatile and workaholic person type. I am real representative of true engineer, because I work better under pressure (e.g. in time critical projects). I can switch from project to project in no time, even work at multiple projects at once. I love working in team, but also I find myself as independent and proactive. I am quick learner, eager and able to learn and develop new skills and fit into new working environment. I'm not afraid of new challenges, opportunities or new jobs, and have hidden passion for traveling. Also I'm eager to learn and explore new things. Love anything that has any connection with electronics (test, break, repair - name it) or even with programming, also I use every chance to design and make some new stuff on my own, especially if it is MCU or PLC based. Also, I have interests in digital photography, TV broadcast and production technologies and techniques, as well as satellite communications regarding electronic news gathering field.

United States - Tests: 2 - Portfolio: 4

Hello, I currently work as an in house application developer for Floor & Decor. I primarily create Angular Web/Phonegap apps and build web services with Dropwizard to populate the data. We also implore bootstrap as the main CSS library and use an angular directives bootstrap library to implement the bootstrap jQuery animations and functions. UX is also a specialty of mine not only through experience but studies. I graduated the University of Georgia with a Cognitive Science degree. This is a cross foundation degree between psychology, computer science, and philosophy. One of the main components was combining behavioral psychology with user experience. This was studied intently in my Human Computer Interaction. I have a lot of experience in general Web Development as well. I have created perl and php scripts for querying data from a mySQL server and displaying via html/css/js. I am well acquainted with Objective-C/Xcode for development of iPhone and iPad Apps. I have setup my own Intranet website for a school at UGA and allowed it to run as a Web service for an iOS app I am developing. I have formal training from UGA in a website/ui design class. I consider myself a great self learner. I taught myself how to create the simple web service for my mobile app as well as perl, php, python, html, css, javascript, angularjs, and objective-c. So no matter your problems, I can figure out a solution.
