Responsibilities:Design and development of software for hardware and software systems:quadrupole mass analyzers, gas chromatographs and other. These are devicesfor qualitative and quantitative analysis of substances and their mixtures.• creation of BackEnd for managing and collecting data from a large numberof devices (microservices/Golang/Networking);• low level development: several embedded solutions based onSTM32(ARM) (ANSI C и С++, Hardware Interfaces);• creating of software libraries for working with hardware components(GoLang, C++, Networking);• development of modules for various data processing and analysis (C++,GoLang);• development UI-applications for commercial software (Qt, C++);BackEnd:Interacting with devices via network, collecting a huge amount of data,processing and providing access to data through API.Initial data processing, special information compression algorithms, encryption.Data delivery in a complex network infrastructure using UDP Hole Punching andother technologies.The software communicates with the low level via UDP/TCP/SCTP.Cloud service for accessing laboratory data via the Internet using mobileApp.In most cases GoLang services are used. In some projects I use C++;Conducted reverse engineering of various proprietary protocols using Wireshark.FrontEnd:The following stacks were used to create UI:• Qt/C++ (desktop apps);• Flutter/Dart (mobile/desktop apps);In addition, the software implemented various device emulators(GoLang/C++/Qt/.NET/C#/Networking).Low Level:Projects without OS.In the low-level software, the STM32 microcontroller controls the stand-aloneoperation of the Ethernet-controlled analyzer (LwIP).Support for working with ADC / DAC using SPI / DMA was implemented.Implemented control of external devices connected to the RS-485 bus.Developed software for several types of display modules with touch screens.Development Tools: C/C++ (Keil uVision & STM32 CubeIDE).We used Scrum and Git.
