Phone: +91-733*-****** Email: ************@*****.*** LinkedIn: linkedin.com/in/cenchudarsk Professional Summary

Mechanical Design Engineer with an MSc in Advanced Mechanical Engineering (University of Liverpool) and hands-on experience delivering end-to-end design projects in SolidWorks, PTC Creo, and CATIA. Skilled in 3D CAD modelling, GD&T, DFM, tolerance stack-up analysis, CFD, and FEA, with a track record of translating functional requirements into fabrication-ready parts and assemblies. Previously worked in a design and manufacturing environment, bridging client requirements and engineering teams across automotive, electronics, and industrial applications. Targeting junior/graduate mechanical design roles where I can contribute to CAD modelling, drawing creation, and design validation while growing a hands-on design career.

Design Projects

Portable UVC Air Disinfection System – Design & Validation 2024–2025 MSc Dissertation, University of Liverpool Tools: SolidWorks, CFD, GD&T, Thermal analysis

• Designed complete enclosure, airflow channels, and thermal management system in SolidWorks for a compact UVC air disinfection unit, including sheet-metal and injection-moulded plastic components.

• Performed CFD-based airflow simulations to optimise UV exposure dwell time and airflow distribution across the disinfection chamber.

• Iterated the design using prototype test data, improving disinfection performance while meeting safety, reliability, and manufacturability constraints.

• Produced a full fabrication drawing pack with GD&T, material callouts, and surface finish require- ments aligned to ISO standards.

Rechargeable Hand Fan – Reverse Engineering & DFM Optimisation 2023–2024 Independent Project Tools: PTC Creo, GD&T, Tolerance stack-up analysis, DFM

• Reverse-engineered an existing handheld fan and rebuilt the complete 3D CAD assembly with manufacturing- ready drawings and full GD&T callouts for all critical interfaces.

• Reduced projected assembly time by 20% and part count by 15% through DFM-led redesign, compo- nent consolidation, and improved assembly sequencing.

• Performed tolerance stack-up analysis across mating interfaces to ensure dimensional compliance under expected manufacturing variation.

• Identified and resolved assembly interference issues at early design stages, eliminating the need for downstream rework.

Work Experience

Sales & Design Support Engineer Dec 2021 – Apr 2023 Bumaas Engineering Solutions & Technologies Pvt Ltd, Chennai, India

• Worked directly with design engineers on 40+ custom component and assembly projects, translating client functional requirements into clear engineering briefs and supporting CAD-based design decisions for manufacturability and cost effectiveness.

• Prepared CAD-supported technical proposals, BOMs, and tolerance specification sheets for automo- tive, electronics, and industrial clients.

• Participated in structured design reviews, strengthening requirement capture and helping reduce de- sign revision cycles by approximately 15%.

1

• Authored 200+ technical documents including component selection rationales, material specifications, and tolerance definitions, building reusable internal reference libraries aligned with engineering docu- mentation best practices.

• Responded to RFQs and tenders with detailed technical write-ups covering component selection, material specifications, and tolerance definitions, developing strong fluency in engineering requirements and design intent.
