  • Full Stack IoT Engineer for Embedded Linux

    Siemens Schweiz AG, Zug
    Mar. 2022 - Current

    Software Engineer at Siemens Smart Infrastructure, where I develop/maintain the existing source code using C++20 and Yocto. Specifically:

    • I develop software for edge devices for building automation systems. The devices are Linux based, mainly on ARM-based processors and the software is written in various languages such as C++20, Rust, Go and Python.
    • I contribute and maintain the internal Yocto Layers of our Linux distribution that is deployed to the devices.
    • I conducted a variant analysis to replace the Docker container runtime in the embedded devices. The replacement was necessary, because Docker does not support IPv6 and there are license complication with Docker. Multiple variant were consider such as k3s and podman and the results demonstrated that Podman is the most suitable container runtime for embedded devices.
    • I implemented the replacement of the Docker container runtime with Podman.
    • I develop unit and integration tests that automatically test the functionality of the devices. The tests are end to end from the edge device to the cloud and they are developed using Python.
    • I implement performance tests to monitor the CPU/Memory usage of the devices. Based on these test, I optimize the CPU/Memory usage of the devices.
    • I extend the API and the cloud connectivity of the embedded devices.
    • I maintain and expand the CI/CD pipelines in Gitlab.
    • I contribute patches to upstream projects that are being used from the devices.
    • I communicate with various stakeholders that are distributed across the globe to align all the necessary use cases and functional requirements.

  • Software Engineer

    AutoForm Engineering GmbH, Zurich
    Sep. 2017 - Current

    Software Engineer at AutoForm Development GmbH, where I develop/maintain the existing source code using C++ and Qt. Specifically:

    • I provide input for architectural changes that improve the performance of the products and help in the maintainability and the quality of the source code. I have been involved in large scale refactoring efforts.
    • I conduct performance analysis of the software using the Intel Inspector memory and thread debugger.
      • I have resolved bottlenecks that lead to the improvement of the performance of the software.
    • I integrate 3rd parties libraries by creating Conan recipes
    • I participated in the modernization of the code base by introducing C++17. A new C interface to decouple the code base from external projects that still had to use oldcompilers was created to keep the necessary ABI compatibility for the external projects.
    • I help in the improvement of the build speed and the modularization of the software by producing packages using the Conan Package Manager and Modern CMake.
    • I maintain the Jenkins CI infrastructure and implement new CI/CD jobs using JobDSL.
    • I develop and deploy Docker images to build the software in different environments.
    • I participated in the implementation of the new “Guidelines” feature of the AutForm R8 product. I provided input that improved the UX and implemented the functionality that automatically checks the correctness of the applied processes in the software
    • I participate in the development of the AutoForm-QuickLink and AutoForm-QuickLinkforNX products. I implement new features and I am responsible for the backwards and forwards compatibility of the zipped XML-based file format of the software.
