Development and support firmwares for SoHo WiFi routers based on RBK-B.Main tasks consist of: - Adapting generic SDK for platform to Client-specific hardware - Writing HAL layers for various SDK components, interfacing with Ethernet, WiFI, Routing, Firewall, Platform-Specific features - Debugging and fixing issues in platform-specific drivers, occured as result of intergarion with SDK or borderline use-cases - Adapting existing platform-specific codebase to requirements inttoduced by new releases of SDK - Providing assistance in reproducing and investigation of bugs occurring on edges between subsystems of different vendors

I’ve brought from the concept stage to the stage of a serial prototype a complex for IoT, which allows users to receive data from sensors using a scripting language and control various devices with the created scripts.Software for microcontrollers:- code porting between different models, manufacturers and architectures- support of legacy code and its refactoring- integration of third-party open-source libraries and their adaptation to the project- developing drivers for the internal and external peripheralsFull cycle device development:- creating proof-of-concept on debug boards- participation in the development of device circuitry in conjunction with circuitry- Debugging and refinement of prototypes- Development of testing for serial production, software and hardware for testingSoftware for Linux:- Yocto build environment setup for building an image of the end system- writing build recipes for third-party libraries- writing an application in QT using the Yocto SDK- setting up remote debugging of applications on the target device in QtCreator- configuration of project via CMake, for building libraries with linking from another projectsSoftware for IoT- Development of firmware for the end IoT device connected via the Thread network- Integration of a proprietary scripting solution into the firmware, providing access from scripts to the functionality of the peripherals- Development of communication protocols between end devices and IoT hub based on CoAP- Development of software for IoT hub using microservice architecture- Development of a data bus for IoT hub microservices- Development of a bootloader for end devices with support for rollback and recovery in case of update errorsThread Radio standard- study of possibilities, specifications, limits of applicability- integration of the OpenThread stack into device firmware- development of application protocols using the functionality of the Thread stack based on the CoAP protocol
