About

Jayraj Parmar: Expert Design Engineer & Manufacturing Solutions Consultant

Professional Overview
I am Jayraj Parmar, a dedicated Design Engineer based in Rajkot, Gujarat. My career is built on a single, core philosophy: Design is only as good as its ability to be manufactured. With a background spanning from high-precision surgical implants to heavy defense machinery and electric vehicles, I provide a comprehensive suite of design-to-production services.

I don't just provide "drawings." I provide engineered solutions that solve manufacturing bottlenecks, automate complex systems, and optimize product performance for real-world application.

Areas of Specialized Expertise
1. R&D and Heavy Defense Engineering
My experience at SAR Auto Products Limited involved high-stakes Research and Development for defense vehicles, including tanks and heavy military trucks.

Legacy Development: I specialize in developing modern parts from complex, old, or barely readable drafts.

Precision Verification: Utilizing CMM (Coordinate Measuring Machine) to compare physical parts against CAD models to ensure absolute accuracy.

2. Automotive & Electric Vehicle (EV) Systems
During my tenure at TATA MOTORS LTD, I worked on the front lines of automotive evolution.

EV Development: I have hands-on experience in the developing and testing of Electric Vehicles, specifically the Tata Tiago and Tigor EV versions.

Root Cause Analysis: I specialize in identifying the root cause of testing failures and resolving them through design modifications in CATIA V5.

Powertrain Optimization: At GTU Motorsport, I designed intake manifolds with "ram effect" to increase air intake and engine power without external force.

3. Industrial Manufacturing & Forging Solutions
At BHT Forge, I focused on the "Design for Manufacturing" (DFM) pipeline for oilfield equipment and automotive parts.

Die Design: I handle the complete design of dies for forging parts.

Standards Compliance: My work is grounded in international standards including API, ASTM, and ISO.

Cost Estimation: I create 3D models specifically to estimate raw material weight and cost, ensuring project viability before production begins.

4. Custom Medical & Surgical Design
As MD at Vyom Surgicals, I lead the manufacturing of custom implants. This requires a mastery of precision and an understanding of highly regulated manufacturing environments.

Technical Toolkit
I utilize the industry's most powerful tools to bring your concepts to life:

Design & Modeling: CATIA V5, SolidWorks, Autodesk Inventor, AutoCAD, and Siemens PLM NX.

Advanced Analysis: Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), and Digital Twin technology.

Process Control: Forging and machining control plans, quality standards standardization, and system design.

Educational Foundation
My practical experience is backed by a rigorous academic pursuit:

Master’s in CAD/CAM (Ongoing): Focusing on the core mechanics of CAD, CAE, and CAM software to drive maximum efficiency from these tools.

Bachelor’s & Diploma in Automotive Engineering: Providing a deep-rooted understanding of mechanical systems from the ground up.

Why Partner With Me?
When you hire me on CAD Crowd, you aren't just getting a freelancer; you are getting an Industrial Adviser.

Problem Solver: I excel at taking "impossible" problems—like unreadable old drafts or assembly line fixture errors—and finding a technical solution.

End-to-End Service: From the "zero" concept phase to final testing and finish.

Global Readiness: I am based in the manufacturing hub of Rajkot but am willing to relocate or work remotely for clients anywhere in the world
