Mechatronics Engineer | 5+ Years FreeCAD & Parametric CAD Specialist Are you looking for an engineer who doesn't just draw 3D shapes, but designs functional hardware systems built for the real world? I am a Mechatronics and Mechanical Engineer with over 5 years of hands-on expertise in FreeCAD, specializing in turning complex mechanical concepts, rough sketches, and automation requirements into precision, manufacturing-ready systems. Because I bridge mechatronics and advanced CAD, I don't just design enclosures or mechanisms—I engineer how moving parts interact, how electronics integrate, and how structural components transition seamlessly from digital models to physical production. ⚙️ MY CORE SPECIALIZATIONS: Advanced FreeCAD Parametric Modeling (5+ Years): Mastery of complex part design, sketcher constraints, part assemblies, spreadsheet-driven configuration tables, and custom workflows. I fix broken dependency trees and build robust, fully editable parametric models. Mechatronics & Embedded Integration: Designing mechanical housings, structural frames, and kinematic assemblies that house microcontrollers (ESP32, Arduino), sensors, actuators, and power management circuits. Design for Manufacturing (DFM) & Tooling: Optimizing designs for FDM/SLA 3D printing, CNC milling, sheet metal bending, and laser cutting. I produce accurate flat patterns, DXFs, and production-ready step files. Shop-Floor & Prototyping Reality: Operating out of a fully equipped workspace with an in-house CNC milling machine and 3D printer, allowing me to validate tolerances, test mechanical fits, and handle end-to-end CAM/G-code preparation. 🛠️ TECHNICAL TOOLKIT & DELIVERABLES: CAD Software: FreeCAD (Primary Expert), SolidWorks, AutoCAD Engineering Disciplines: Kinematics, load path analysis, mechanism optimization, and tolerance stack-up management Deliverables: Clean parametric .FCStd files, .STEP exports, 1:1 DXF flat patterns, 2D technical drawings, and detailed Bills of Materials (BOMs) 📌 RECENT RELEVANT PROJECTS: Aircraft Structural Framing & Ribs: Modeled structural frames, tapered aerodynamic surface definitions, and tooling/form block workflows. Autonomous Robotics (AMRs) & Mechanical Chassis: Designed modular robotic frames, drive assemblies, and precise sensor/actuator mounting brackets. Parametric Reconfigurable Enclosures: Engineered complex, multi-part articulated systems driven by custom parametric logic and snap-fit mechanisms. If you need a reliable mechatronics expert who knows FreeCAD inside-out and delivers production-grade designs without guesswork, let's connect and bring your hardware project to life.
