Marion B.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Aug 7, 2026.

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.
