Embedded Systems & Automation Engineer

Bridging the gap between physical hardware and bulletproof software.

I am a software developer and automation engineer specializing in the design of advanced IoT controllers, security systems (radar and microwave sensors), and industrial logic. My primary goal is to deliver code that is 100% tested in a virtual environment before it even touches the physical devices on the factory or warehouse floor.

My Tech Stack & Toolkit

Technology / Environment Area of Expertise
ESP-IDF & FreeRTOS Advanced programming of ESP32 microcontrollers (Xtensa architecture). Multithreading, memory optimization (IRAM), and Direct Register Access.
C / C++ The languages I write with surgical precision. I focus on low-level optimization, zero-latency execution, and memory safety.
Visual Studio Code (VS Code) My primary, fully customized development environment for code analysis, debugging, and deployment.
Qt Framework Designing modern, native, and highly responsive Graphical User Interfaces (GUI) for HMI systems and touch panels.
Virtual Commissioning Utilizing digital twins (Factory I/O) to test PLC logic (TIA Portal, CODESYS). I protect my clients' hardware from unexpected deployment failures.

 

Why entrust your project to me?

  • Fail-Safe Architecture: I design fault-tolerant systems. If cloud communication fails, the hardware watchdogs I implement will autonomously secure the infrastructure (e.g., cutting off zone power).

  • Industrial-Grade Security: I implement hardware-level cryptography (AES-GCM, secure OTA updates) to protect devices from external attacks and replay threats.

  • Edge AI Ready: My software architecture is optimized for deploying local Artificial Intelligence algorithms (e.g., advanced filtering of false alarms from radar sensors).

Hello, I'm Andre Stepniewski

I'm an Automation Engineer passionate about bridging the gap between virtual design and physical reality.

I specialize in developing PLC logic with a heavy focus on Virtual Commissioning. My goal is simple: to deliver code that is 100% tested and ready for action before it even reaches the factory floor. By using Factory I/O as a digital twin for CODESYS and TIA Portal, I save my clients time and protect their hardware from unexpected errors.

As a Junior Engineer, I bring a fresh, tech-forward perspective to every project. I don't just "write code" – I build simulated environments to ensure every sensor, motor, and safety interlock works perfectly.
