Sobre mim
Hello my name is Stanley, I design manufacturing ready hardware: high voltage PCB layouts, DC DC converter schematics, and power electronics boards in Altium Designer & KiCad, plus 3D CAD work - STL mesh editing, embossed logos, and AI/SVG/PDF to STEP conversion for injection molding. I deliver DRC clean layouts, verified creepage and clearance, complete Gerber & drill sets, BOMs, and production ready STEP files. From schematic capture to fab output and mold ready geometry, I help startups, engineers & product teams move from concept to factory floor. Message me with your specs before ordering... Saiba mais

Experiência profissional

Auto-Mow

Technical Consultant

Auto-Mow • Freelance

May 2026 - Jul 20262 mos

Provided technical consulting to hardware startups and independent inventors requiring early stage electronics and mechanical design support. Reviewed existing schematics and PCB layouts to identify layout risks, thermal weaknesses, EMI vulnerabilities, and cost optimization opportunities before clients committed to fabrication. Advised on component selection, layer stackup, manufacturer capability matching, and design-for-manufacturing (DFM) improvements. Delivered written reports summarizing findings, recommended fixes, and alternative design approaches to reduce respin risk. Supported clients with sourcing strategy, connecting them with reliable PCB fabricators and assemblers, and reviewing quotes from Asian and US based suppliers. In parallel, offered mechanical CAD support reviewing STEP models for enclosure fitment, verifying tolerances, and preparing files for injection molding tooling. Maintained long term relationships with several repeat clients through NDA based engagements

Fiverr

3D CAD Designer

Fiverr • Freelance

May 2026 - May 20260 mos

Provided 3D CAD conversion and STL editing services to product designers, 3D printing shops, and small manufacturers. Converted 2D vector artwork including Adobe Illustrator (AI), SVG, and PDF files into manufacturing-ready STEP models suitable for injection molding, CNC machining, and additive manufacturing. Modified existing STL meshes to add embossed or debossed logos, split multi-part assemblies, repair broken geometry, and prepare files for high-quality resin and FDM 3D printing. Applied proper draft angles, wall thickness, and fillet radii to ensure moldability and printability. Used Fusion 360 and SolidWorks for parametric modeling and reverse engineering, and Meshmixer or Blender for high-polygon STL cleanup. Delivered clean, watertight files in STEP, STL, and OBJ formats with dimensional verification and 3D preview renders for client review. Maintained rapid turnaround while handling revisions and confidential product files under NDA.

PCB Design Engineer

Elect SPARGO • Freelance

Jan 2026 - Mar 20262 mos

Delivered custom PCB design services to international clients across industrial automation, e-mobility, and IoT sectors. Designed multilayer boards (2 to 6 layers) for DC-DC converters, motor drivers, and mixed-signal systems using Altium Designer and KiCad. Handled complete workflows from block diagram to manufacturing outputs — including schematic capture, component selection, footprint creation, layout, DRC/ERC verification, and generation of Gerber, NC drill, BOM, and pick-and-place files. Applied IPC-2221B creepage and clearance rules for high-voltage designs up to 600V and optimized copper pours for high-current nets exceeding 40A. Collaborated with clients through detailed design reviews, delivered STEP models for mechanical fitment checks, and handed off manufacturing-ready packages to fabricators such as JLCPCB, PCBWay, and OSHPark. Maintained strict NDA compliance and clear technical documentation throughout every project cycle
