I turn ideas into working hardware, fast. From first principles to factory-ready files, I design and build complete products: mechanisms, electronics, firmware, and test rigs that survive real-world use. Top Rated Plus, 100% Job Success, 2,000+ hours on multi-month R&D and product builds. What I do best -Robotics & Mechatronics: Motor/gearbox sizing, kinematics, control (PID/FOC), actuators & sensors, reliable motion paths -Embedded & PCB: STM32/ESP32/Arduino, C/C++, Altium/KiCad, bring-up, drivers, test firmware -Mechanical Design & DFM: SolidWorks/Fusion 360, tolerance stacks, materials, manufacturing drawings -Rapid Prototyping: 3D printing/CNC, bench fixtures, data-driven iteration, demo videos for stakeholders Typical outcomes -A first prototype in 2–6 weeks with the right trade-offs for speed vs. reliability -Clear, version-controlled DFM packages suppliers can quote without missing details -Repeatable test results (e.g., duty cycles, torque/temperature margins) you can build your roadmap on Industries I’ve delivered for -Humanoid & assistive robotics, consumer hardware/IoT, lab & test equipment, education/STEAM devices, environmental tech (atmospheric water & thermal systems), and special-purpose mechanisms. My process (no guesswork) -Discover – Align on goals, constraints, risks -Architect – Select mechanisms, electronics, and control approach with a risk map -Prototype – CAD + PCB + firmware; focused experiments answer the hard questions first -Validate – Instrumented tests, logs, and short videos; iterate on evidence -Handoff – Manufacturing drawings, BOM & alternates, bring-up notes, maintenance docs Deliverables you can expect -CAD & manufacturing drawings (GD&T, tolerances, exploded views) -Schematics, PCB layout, Gerbers, assembly notes, and test points -Firmware (C/C++), configuration files, and a bring-up checklist -BOM with supplier options (cost/lead time/alternates) -Test plans, data summaries, and short demo videos for decision-makers Tooling & stack -Autodesk Inventor/AutoCAD • Altium / KiCad • STM32 / ESP32 / Arduino • BLDC/servo control • Python for data & utilities • 3D printing/CNC protos • DFM/DFA How we’ll start Share your goal and constraints; I’ll reply with a lean prototype plan (milestones, timeline, and risks addressed up front). If you prefer, we can begin with a 60–90 min architecture call to de-risk your approach and lock specs. If you need a product developer who can own the path from concept to proof—and hand it to manufacturing cleanly—let’s talk.
