My team builds bespoke industrial equipment and to date every chassis, PCB, and line of firmware has been produced in-house. As we scale, I want to assemble a reliable shortlist of external partners who can jump in when workload or lead-times demand it, specifically for the design and prototyping stage of new products. The scope spans three tightly-linked disciplines: • Mechanical engineering – rugged enclosures, heat management, motion components • Electrical engineering – board-level design, power distribution, compliance-ready layouts • Firmware development – microcontroller code, hardware abstraction layers, rapid bring-up To make the shortlist, please share: • A concise portfolio of comparable industrial projects (photos, schematics, or code snippets are fine). • A brief outline of your toolchain—e.g., SolidWorks/Fusion, Altium/KiCad, STM32Cube/MPLAB, C/C++, MicroPython/Python, etc.—and any lab resources you own for rapid prototyping. • Typical turnaround times for first articles and the engagement model you prefer (fixed scope, time-and-materials, mixed). • Any certifications, testing facilities, or partnerships that help you hit CE, UL, or similar marks early in the cycle. I will review every submission for technical depth, clarity of communication, and fit with our existing processes.

Hi I am an embedded systems engineer with over 16 years of experience in industrial hardware, embedded firmware, and consumer-grade product development from concept to prototype and production support. Your scope matches the kind of work I usually handle: rugged enclosure design with thermal and mechanical constraints, PCB-level design for power/control boards, and fast firmware bring-up on STM32, PIC/AVR, ESP32 and similar MCU platforms. I work comfortably across SolidWorks/Fusion 360, Altium/KiCad, STM32Cube/MPLAB, C/C++, Python/MicroPython, test jigs, oscilloscopes, logic analyzers, bench supplies, soldering/rework, and rapid prototype fabrication through 3D printing/CNC/PCB assembly partners. Comparable project details, photos, schematics and code cannot be shared publicly, but I can show relevant examples privately after we discuss confidentiality. Typical first article timing depends on complexity, but early architecture and feasibility review can usually be turned around in a few days, with PCB/enclosure prototypes commonly in the 2-4 week range once requirements are stable and fabrication lead times are known. I can work time-and-materials for overflow engineering, fixed scope for defined prototypes, or a mixed model where discovery is hourly and build packages are fixed. I also design with CE/UL-style constraints in mind early: grounding, isolation, creepage/clearance, EMI, thermal margins, documentation and test planning. A few useful details to confirm would be target industries, expected volumes, environmental ratings, preferred CAD/EDA formats, and how much of your existing internal process you want an outside partner to follow. Please contact me to discuss details.

Industrial product development succeeds when enclosure design, thermal management, manufacturability, and electronics integration are considered together from the first prototype rather than treated as separate tasks. My primary focus is mechanical engineering for industrial equipment, including rugged enclosure design, structural optimization, thermal considerations, motion-related components, and prototype-ready CAD development. I regularly develop designs intended to integrate seamlessly with PCB assemblies and embedded hardware while keeping manufacturing constraints in mind. My typical workflow includes: - Reviewing requirements and defining mechanical interfaces with the electronics architecture. - Developing parametric CAD models and prototype-ready assemblies in SolidWorks. - Performing design validation through engineering analysis where appropriate. - Delivering manufacturing documentation and supporting design iterations. Deliverables include SolidWorks source files, STEP, PDF manufacturing drawings, BOM (when applicable), and design documentation. Up to two revision rounds are included. This proposal is based on the current project description. Additional features or engineering disciplines outside the agreed mechanical scope can be quoted separately. Physical fabrication and testing are excluded unless explicitly agreed. The final schedule will be confirmed after reviewing your existing documentation and design standards. The proposed rate is preliminary to start the discussion. Could you share whether your mechanical work is typically sheet metal, CNC-machined assemblies, or injection-molded products?
