About

I'm Mahesh Rathva, a mechanical design engineer specializing in CAD/CAM and product design — proficient in SolidWorks, Fusion 360,Autodesk Inventor, Solid Edge, Onshape, and MATLAB for Design analysis and simulation.

What sets my design work apart is manufacturing-floor experience most CAD freelancers don't have. As a Jr. Associate Engineer (Production) at Greenply Speciality Panels Pvt. Ltd., I operated and optimized MDF sanding lines, cut machine downtime by 15% through workflow improvements, and managed preventive maintenance, belt/pad changes, and quality checks on live production equipment. That background shapes how I design — for tolerances, assembly, and machinability, not just appearance.

I've also taken designs end-to-end from CAD to working prototype, including full mechanical design and manufacturing of a six-legged hexapod robot (Robofest 3.0 finalist) and a portable thermoelectric cooling system for off-grid use, plus contributions to WaveZen (AAKRUTI semifinalist) and Smart India Hackathon.

I bring practical, production-informed CAD and product design to client projects. Let's talk about what you're building.

Experience

Mechanical Engineer – Design Advancetech · Full-time Feb 2026 – Present 6 mos Por, GJ, India Handle mechanical design and drafting using SolidWorks and AutoCAD, including preparation, modification, and review of technical drawings, layouts, and basic design calculations to project and company standards. Provide daily support to production and manufacturing teams, coordinating with shop floor personnel to keep manufacturing activities on track and resolving minor technical issues while ensuring adherence to approved drawings and processes. Maintain documentation, inspection records, and daily progress reports for management review.
Production Engineering (DFM/DFA credibility anchor) Greenply Specialist Panel Pvt. Ltd. · Full-time Aug 2024 – Jan 2026 1 yrs 5 mos Savli, GJ, India Operated and optimized MDF board sanding lines, ensuring defect-free finishing and consistent surface quality. Reduced machine downtime by 15% through workflow improvements, supported preventive maintenance planning to cut breakdown frequency, and managed sanding/printing system upkeep — belt changes (60–180 grit), graphite pads, bag filters — alongside daily production and maintenance reporting. This hands-on manufacturing exposure directly informs how I approach design for manufacturing and assembly (DFM/DFA) in CAD work.
Mechanical Design Lead — Hexapod Robot The Robotic Society of India (TRS) Student chapter BVM · Internship May 2022 – Jan 2026 3 yrs 8 mos Anand, GJ, India Owned the complete mechanical design of a six-legged hexapod robot from concept to working prototype. Modeled all components in Fusion 360, ran motion studies and simulations to refine leg mechanisms and structural fit, then managed sourcing, manufacturing, and physical assembly of the prototype. Iterated through testing and troubleshooting cycles to reach final approval, and led the team to the Robofest 3.0 finals.

Education

Birla Vishvakarma Mahavidyalaya Engineering College B.TCH, Mechaical Engineering, C 2020 – 2024 Activities and Societies: The Robotics Society of India (TRS BVM), Bachpan NGO, Kho-Kho, Hockey, and Football. I am a member of TRS where I have gained valuable knowledge in Fusion 360 software, robotics, 3D printing, and various technical skills.

Additionally, I dedicate my time to teaching at Bachpan NGO, assisting students from 6th to 10th grade who cannot afford tuition due to financial constraints.

In my leisure time, I enjoy playing Kho-kho, Hockey, Football, Volleyball, and engaging in online chess matches.

Other experience

Portable Cooling System: Minor Project I Designed a compact, portable thermoelectric (Peltier-effect) cooling system for off-grid use. Modeled the hot-side and chamber-side heat sink assemblies and the refrigeration chamber layout, balancing thermal output against a 25×19.5×17 cm footprint. Validated the design against real cooling-performance data across multiple load tests.
