- Development of the Java Android Auto Media app for the client. Work with AOSP, repo tool, Jenkins&Gitlab. Testing, debugging, working with client, writing documentation both in code and Confluence, automation. Used Java, Postgres, Gradle and worked in a multithreaded environment.

- Development of the C++17 Android Auto Process Health Monitor app. The project is a daemon that continuously scans for overuses (CPU/RAM/IO) to help maintain stability of the Android Auto system. It provides a HAL API for other packages. Using C++17, Android and Linux APIs and multithreading. Creating unit, instrumentation and integration tests. Working on a development rig.

- Development of the Camera QNX application. Displaying camera views in the Camera Android Kotlin application using GStreamer for the C++ QNX layer.

I worked with a product that allows to scan for defects of containers of different kinds. The solution utilizes AI for quality inspection to classify and mark samples on a production line. I also utilized Gstreamer to create pipelines to stream photos from cameras to destinations specified by customers.

I took part in 3 projects:

- a project taking advantage of low-power microcontrollers, able to gather data and perform simple AI analysis (decision trees) for in-house decision management, based on decision trees generated beforehand. At the end, the project allowed for quite effective detection of drilling, reaching as much as 80% accuracy for recognizing states (drilling, not drilling, steady, moving);

- a project using Unity to carry out simulations inside virtual environment to prove that it is possible to detect potentially dangerous objects to autonomous forklifts inside a warehouse;

- a project about an Android phone and screen development for it (main project since July), mainly things around Repo, Git, manifests, AOSP, vendor libraries, testing with CTS and VTS, HAL interface development and et cetera.

I created a banking system for fast transaction processing, using the FIX protocol (C++ QuickFIX), Boost, C++17 and CMake. The system utilizes parallelism in the application, allowing for creation of multiple threads, ready to serve connections and contact with the bank. It provides a REST API and balances load, using a thread pool and a concurrent hashmap.

Fixed bugs in existing code in order to improve customer satisfaction from the developed product.
Worked with product owner, which helped me improve my soft skills.
Used Git extensively to work with version controlling, taking advantage of various commands.
Implemented new features, trying to adapt the code to the newest standards on my way.
Learnt and applied flight (pilot and crew) rules into the validation code.

Debugged kernel code (Linux and FreeBSD).
Compiled kernels and worlds for several architectures.
Made drivers and developed software for Marvell Armada platforms in UEFI environment.
Used Git extensively to manage the code and branches (resetting, rebasing, bisecting, amending commits, etc.).

Created GUI tools in Python to help automate compilation processes.
Created GUI tools in Python for sending diagnostic signals to truck radars.
Developed low-level MISRA-compliant C code for SCANIA radars.
Neutralized hundreds of compilation and QA C warnings in the C radar code.
Made unit tests with VectorCAST software.
Debugged C code on SCANIA radars using Lauterbach debuggers.
Used Plastic as a version control system.
