I specialize in developing desktop as well as embedded applications for the client's bespoke hardware instruments. This includes software for advanced hardware control (including actuators like stepper motors, valves etc.) with output data acquisition and applications for data visualization and analysis. On prototyping / R&D stage as well as creating an end-user application. I can provide a logic underneath that handles an instrument-specific communication (through e.g. USB/Ethernet/CAN Bus or Serial line), along with a user-friendly graphical interface. Also, having a background in automatic control and robotics, I am familiar with implementing control algorithms that are fitting for a particular use. So whether you need a tool to prototype your ideas, or to control your end product I will be happy to help. I use an agile approach in my work, which accompanied by good contact with a customer allows adapting easily to any changes. My previous working experience includes e.g. companies from the medical devices field, which meant working closely with scientists to adjust the software to their specific needs. My environment of choice for desktop applications is Python with a Qt framework wrapper (PySide2), which results in a short implementation time and robust user interface. Another advantage of choosing Python is that the same code can be easily distributed for any platform - Windows, Linux or Mac. I am part of WizzDev - a custom embedded software development company based in ⭐Poland. We have strong experience with developing low-power IoT devices including production support and deployment in the EU and UK. As a company, we were involved in many projects which include firmware development, custom hardware design, and IoT cloud integration. ⭐Firmware features I can help with: STM32/ESP32 development; Communication peripherals (SPI, UART, I2C); Multithreaded code using FreeRTOS Hardware control (including sensors and motors) C/C++/Python programming languages; Displays and multiple LEDs; MQTT with AWS IoT Core; Various wireless communication protocols including WiFi and BLE
