I’m a skilled RF and mmWave hardware engineer specializing in antenna and PCB design, with extensive experience in the automotive and wireless industries. My work spans all stages of development - from early concepts and circuit planning to detailed electromagnetic simulation, prototyping, testing, and validation. I use industry standard tools like CST Studio Suite, Ansys HFSS, Altium Designer, KiCad, Altium, SPICE, and FreeCAD for design, simulation, and mechanical integration — making sure each stage of development connects smoothly from concept to realization. In addition, I maintain a small RF lab equipped with a vector network analyzer, spectrum analyzer, oscilloscope, and all other tools needed for soldering and prototyping, allowing me to test and verify designs hands-on. I enjoy tackling projects that combine simulations and practical hardware work. Whether it’s developing antennas, optimizing RF circuits, designing PCBs, or helping with various electronics projects, I aim to create solutions that work reliably in the real world :)

C# / WPF Developer & Industrial Automation Engineer — 20 Years of Experience I build desktop software that talks directly to machines — and I've been doing it for over 20 years. My background is unusual: I started as an automation and service engineer, then moved into full-cycle software development. Today I sit at the intersection of high-performance desktop applications, industrial control, and modern backend integration — a combination that's genuinely hard to find in one person. What I bring to your project: ▸ Desktop Applications (C# / WPF, Delphi) High-performance Windows apps with clean architecture, MVVM, CI/CD pipelines, GitHub Actions, installer packaging (Inno Setup), license management (Sentinel / Thales). Experienced in commercial projects include CNC machine control applications, a CAD/CAM platform with a 3D engine integrated in WPF, and multiple smaller tools controlling industrial hardware. ▸ Industrial Automation & CNC Deep expertise in CNC motion control systems, G-code processing, CAM toolpath logic, PLC programming (Ladder, ST etc.), servo drives, EtherCAT, CANopen, Modbus etc. and machine-level integration. I know how machines actually work — not just the software layer. ▸ Robotics & Cobots Integrating industrial robots and collaborative robots (cobots) through available APIs (ROS2 cobots and C++/C# API). ▸ ERP & System Integration Custom integrations between production software and ERP systems (COM, REST API). Web API in C# (.NET), multi-tenant SaaS architecture, Supabase, Stripe, Railway. ▸ Embedded & Hardware AVR and ARM microcontrollers (including Arduino-compatible, ESP etc.), RS-485 / Modbus, custom hardware interfaces. I read and draw electrical schematics (PCSchematic). I design and print enclosures and mechanical parts as well as design PCBs (FreeCAD, Bambu Lab, KiCAD). ▸ Full-Cycle Ownership From architecture and requirements through deployment and maintenance. Git (GitFlow, multi-repo), tests, clean documented code. If your project involves desktop software, machine integration, ERP connectivity, robotics, or anything where the software needs to understand the physical world — let's talk.
