Clean 2D CAD drawings from your PDFs, sketches and redlines. Available for small test tasks or single drawings. I help engineers and contractors turn existing inputs into accurate, structured CAD drawings — without redesign or guesswork. My work focuses on documentation and drafting execution, not engineering design, system sizing, or calculations — which allows me to support teams that need reliable drawings without added interpretation risk. What I can help you with: • PDF / scan → clean 2D CAD (DWG/DXF) • Redline markups → updated drawings • Drawing updates and corrections • Mechanical & piping layouts (based on your inputs) I focus strictly on drafting and documentation — no design, no calculations — so you get exactly what you specify, fast and accurately. I work with AutoCAD-compatible software (DWG/DXF) and FreeCAD, and deliver clean, review‑ready files (DWG / DXF / PDF) structured for practical use. When provided, I can reference existing 3D models to ensure accurate 2D output, but my primary service is high‑quality 2D drafting. Typical turnaround: 24–48h for small drawings. Background: Mechanical engineer with experience in industrial pipeline and infrastructure drafting. Used to working from real project inputs, markups, and site-based sketches. If you have a drawing task, send your files and I’ll let you know how quickly I can deliver.

I’m a 3D CAD designer and hands-on prototyper with a background in Robotics and Mechatronics Engineering, skilled in turning ideas into functional prototypes. I specialize in clean, efficient modeling using SolidWorks and Fusion 360, and have extensive experience in 3D printing, slicing, and preparing models for high-speed, precision manufacturing. Beyond design, I bring strong electronics and embedded systems expertise, having built robots and custom hardware projects involving Arduino, Raspberry Pi, sensors, and wireless control systems. I’ve created everything from self-balancing robots and gesture-controlled prosthetic hands to morphing drones and mobile manipulators -combining CAD, fabrication, and electronics integration. 1. 3D Modeling & CAD – Mechanical/product/enclosure design using SolidWorks/Fusion 360 2. 3D Printing – Preparing and slicing models (UltiMaker Cura, Bambu Studio), troubleshooting prints 3. Basic Animation & Rendering – Functional visualizations for client demos or concept presentation 4. Functional Prototyping – Sensor integration, motor control, clean wiring, sealed assembly 5. Component Fit Testing – Real-world validation of spacing, alignment, and tolerances 6. Integrating electronics – Arduino, Raspberry Pi, motor drivers, sensors, LCD and Touchscreen
