Intelligent virtual care system ensuring continuous monitoring of patients. Proven to reduce costs, improve patient outcomes, and keep nursing and support staff safe on the job • Integrate the embedded development team and understand the workflow: agile based, git and GitLab for version control, Youtrack for planning, Jenkins for CI/CD and Yocto as build system • Replace existing RTSP Video conferencing solution with gstreamer WebRTC to enable secure peer to peer communication: o Create Yocto recipe for the new solution. o Set up build environment using CMake and integrate spdlog as logging library. o Create gRPC wrappers to enable the main application to control the flow of the webrtc call. o Develop webrtc call logic: SDP, ICE candidates, Media transceivers, Data channels. o Test and debug the application with the client’s webrtc peer. o Increase the level of security by integrating AES-256 encryption in gstreamer 1.18. • Improved audio processing pipeline by integrating PulseAudio for better echo cancellation. • Worked on the graphics stack to enable seamless switching between web app and video stream: o Try to run both applications in wayland compositor: issue with color format conversion from the h264 video decoder (NV12) to a wayland sink. o Integrate graphics libraries (gtk, directFB, ..) and try to make them run in linuxFB. • Diagnosed and resolved network issues: o Resolved wpa_supplicant TLS certificate parsing issue by modifying the recipe to use openssl instead of GnuTLS o Configure iwlwifi kernel driver as builtin and as a module. o Update iwlwifi-backport driver to latest version for better security, patch it to resolve build issue, and debug connectivity issue when access point doesn't provide country information.

Project: BLE communication module for power tools/ German company • Create specifications and design the system with the client. • Development environment setup: o Setup a scrum-based development process and a bi-weekly customer synchronization meetings o Setup hardware verification process to exclude any hardware problems that may occur. o Integrate a logging library for debugging. o Set up CI/CT/CD pipeline using Azure DevOps to streamline development, testing and deployment. • Development of Firmware update mechanisms: o Set up the boot image manager to check, copy and run images in external flash. o Set up a rescue image mechanism to always have a fallback when the new image fails checks. o Implement a serial bootloader to receive images from serial (mainly used in manufacturing). o implement a Firmware Over-The-Air (FOTA) mechanism to enable updating the image over Bluetooth low energy. o Integrated security features in the bootloader, including CRC and ECDSA signature verification. o Implemented a secure public key update GATT service to enable updating ECDSA keys. • Development of main application: o Implementation of a remote procedure call system to enable configuration and control of the module. o Configure the module as both central and peripheral to account for role changes. o Configure the advertisement data based on configuration received. o Design and implement state machines to control the behavior of the module. (role, advertisement, scanning, pairing, coupling, connection) o Enable L2CAP communication between nodes in the network. o Create GATT services to enable communication and expose functionalities to smartphone app. o Developed a secure channel system to ensure communication is restricted to authorized users. • Defined and automated test cases to ensure robust functionality.
