Márk Rostás is a Development Engineer | Embedded Systems | IoT | C Programmer at Moonsyst International. Colleagues describe them as "Márk is a result-oriented and self-inspired professional whose personal characteristics and skilled background contributed to the success of one of my most critical projects at my former employer. He is a down-to-earth engineer with a client-focused approach that makes him inevitable within the development team. As a thinker, he hunts for expertise and knowledge and is unafraid to face new challenges. His responsiveness and availability are assets for the customers of Z Elektronika. He has a wide range of experience with microcontrollers manufactured by STMicroelectronics and Espressif and is also familiar with IoT. As a separate project, he prototyped a device based on KICAd (hardware) and Qt (software). In the said project, he managed to get extensive experience in different peripheries and protocols such as FIFI/ETHERNET, OTA, MQTT, HTTP/HTTPS, TCP, UDP, FATFS, RS232, RS485 and I2C. As for STM microcontrollers, he conducted the development procedure of a LoRA-based device. As a test engineer, he built a piece of complete test equipment using Labview and this enabled him to see through the production processes from his office desk to the finished product. I am grateful for the opportunity to have him as a co-worker."
