I build hardware products where electronics, mechanics, and control systems have to work together cleanly from day one. My work covers PCB design, CAD, IoT devices, Raspberry Pi integrations, PLC-based control systems, and product development for teams that need practical engineering, not disconnected design tasks. I support projects from concept development through prototyping and production preparation, with a strong focus on reliability, manufacturability, and real-world use. My experience includes schematic design, PCB layout, component selection, BOM development, enclosure design, 3D CAD modeling, and design for manufacturing. I regularly work on products where electrical and mechanical constraints must be solved together, especially in embedded and connected systems. That includes board size, connector placement, thermal behavior, enclosure fit, mounting strategy, assembly flow, and service access. I also work with Raspberry Pi when a project needs device control, edge processing, communication, or rapid hardware integration. For automation and industrial environments, I support PLC-based systems where dependable control logic, field integration, and serviceability matter. I approach product development with a business mindset because a design is only valuable if it can be built efficiently, tested properly, and moved forward without unnecessary redesigns. I stay focused on engineering decisions that affect timeline, cost, product quality, and long-term maintainability. My working style is structured, professional, and detail-driven. Clients value clear communication, organized deliverables, and engineering work that is grounded in production reality. My goal is to help companies develop hardware products that are solid technically, practical commercially, and ready for the next stage.

I bring 15+ years of international experience across firmware, hardware, PC-system software, and bespoke applications for embedded systems. I take products end-to-end—from concept and architecture through electronics, firmware, mechanical design, and production. In-house, I handle mid-scale builds (down to 0402 and fine-pitch BGAs) with pick-and-place, reflow, and full validation, source components globally, and coordinate seamlessly with external PCBAs for higher volumes. Instead of juggling multiple suppliers, you get one partner who integrates hardware, software, and mechanics into a cohesive, production-ready solution. If you’re looking to turn an idea into a reliable, manufacturable product, let’s connect.
