About
Senior mechanical design engineer with 25+ years of production design experience, specializing in CATIA V5 (Part Design, Assembly Design, Generative Shape Design, Sheet Metal Design, and Drafting) and GD&T per ASME Y14.5.
I take parts and assemblies from concept through detail drawings, tolerance stack-up analysis, and production release, and I select and apply GD&T datum and tolerance schemes during design, not only check them afterward. I have also served as a GD&T and engineering-standards reviewer for other design teams, giving precise written feedback rather than simple approval.
Core expertise:
GD&T selection and application in design (ASME Y14.5)
Tolerance stack-up analysis and DFM/DFA review
Control gauge and measurement fixture design built directly from drawing requirements
Fixture and special-purpose tooling design for machining and assembly line production
CATIA V5 across Part Design, Assembly Design, Generative Shape Design, Sheet Metal Design, and Drafting
DFMEA/PFMEA contribution and Control Plan authoring
Selected results:
Led a dimensional investigation that took a critical subsystem from 80,000 PPM to zero defects, a result that has held for over four years
Piloted FDM 3D printing for functional control gauges, cutting lead time by 93 percent and cost by 87.5 percent, later adopted as the standard across new programs
Solved a chronic supplier machining deviation by redesigning fixture locators, fully eliminating recurrence
Wrote a CATIA macro that automated drawing dimension labeling, cutting drafting time by roughly 50 percent
Designed special-purpose tooling for a 10-station turbocharger assembly line, including pneumatic clamping fixtures and
I communicate clearly in English, mentor and train other designers, and produce technical GD&T educational content. I work well independently with distributed and remote teams.

Experience
- Senior Technical Consultant Basa Pars Sanat, (merged Tondshar / Basa Pars Sanat factory / Shaygan) · Full-time Mar 2026 – May 2026 2 mos Tehran, Tehran Province, Iran Served as GD&T and engineering-standards reviewer for water pump, CVVT, and OCV design teams, evaluating designs and drawings against ASME Y14.5 and providing written technical feedback. Continued turbocharger design work and applied engineering calculation to support design decisions. Mentored a junior designer and trained a successor to take over technical responsibilities.

Joined as the sole engineer in R&D and built and trained the engineering team from scratch over the following years, developing technical knowledge in GD&T, gauge design, and dimensional management without external support, and sharing that knowledge openly across departments. Sole technical authority for mechanical design, taking parts and assemblies from concept through detail drawings, ECR/ECN, and production release in CATIA V5. Served as the OEM-facing technical contact via IPCO (agent for IranKhodro), resolving technical requirements and design limitations directly with customer representatives. Key technical contributor on DFMEA/PFMEA review committees and personally prepared Control Plans from drawings and requirements.
Key achievements:
80,000 PPM to zero: Led a dimensional investigation on a critical subsystem, identifying four tooling root causes and one process control gap. Implemented corrective actions with the supplier, and the defect rate dropped to zero and has stayed there for over four years.
3D printed control gauges: Pioneered FDM 3D printing for functional gauges, cutting manufacturing lead time from one month to two days (93 percent reduction) and cost to one eighth of the conventional method (87.5 percent saving). Adopted as the standard for all new pipe programs.
Supplier fixture fix: Solved a chronic housing machining deviation through an on site fixture inspection, discovering that surface locators were referencing cast flash. Replaced them with point locators and validated the fix on two parts with very different flash conditions, permanently resolving the problem with zero recurrence.
CATIA automation: Wrote a Visual Basic macro that automatically labels drawing dimensions by position, eliminating manual labeling errors and cutting drafting time by roughly 50 percent.
Assembly fixture redesign: Replaced a failing pneumatic fixture with a custom magnetic solution, self taught with no prior magnetic design experience, improving alignment precision and reliability and eliminating a bottleneck on the assembly line.
Designed special-purpose assembly line tooling for a 10-station turbocharger line, including pneumatic clamping fixtures and LVDT-based clearance measurement stations. -

Started my career in steering and suspension component procurement engineering, responsible for first article inspection against drawings and control plans, and for approving first production samples. Built part quality control processes and created inspection and acceptance checklists.
Became fluent in BOM structures and, drawing on my strength in database data analysis, developed an innovative method for storing BOMs across several similar products with common parts, which was adopted by the engineering department.
Completed a 150 hour CATIA training course and, given the high volume of modeling and drafting work, became fully proficient in Part Design, Assembly Design, Drafting, Generative Shape Design, and Sheet Metal Design.
Key contributions:
Designed complex sheet metal prototype vehicle bodies using creative fixturing methods, including brake forming and welding.
Designed an innovative assembly fixture using magnetic solutions, improving reliability and alignment.
Taught CATIA at Iran's Mould Makers Society Training Centre.
