Responsibilities:- development of a payment application for POS terminals, support for the EMV standard, implementation of protocols for interaction with processing centers. While participating in the project, I gained experience working with cmake, git, writing unit tests using the UnitTest++ framework.Achievements:- developed the protocol of interaction of the terminal with the processing center of the BPC;- added implementation of payments using the SBP service for the Compass Plus processing center;- added implementation of acquiring/issuer discounts/commissions.

I was doing research on experimental stands, soldering circuits. In the last year of working here, I gained experience in developing on microcontrollers.Responsibilities:- launching and commissioning of experimental installations, stands and measuring systems;- development of electrical circuits;- development for microcontrollers;- development of GUI applications.Achievements:- developed a management system for a multichannel laser installation. The system consists of a control block and a program running on a PC. The control block consists of STM32 microcontrollers that manage the experimental stand. The control block communicates with the PC via Ethernet (UDP protocol). The management program on PC is a GUI application developed using the Qt framework.- developed a four-channel 64-bit photon counter on the STM32 microcontroller. The counter is controlled from a PC via a GUI application.
