# Vangala Sai Sagar on Tal

## Headline

Engineering Change Specialist \| PLM – Enovia V5 & Aras \| BOM & Configuration Management \| Onshore Wind Turbine ECO/ECR \| Six Sigma Green Belt \| TCS \(GE Vernova\)

## About

4\+ years managing 500\+ Engineering Change Orders \(ECOs\) and 60\+ ECRs for GE Vernova's Onshore Wind Turbine product lines at Tata Consultancy Services — using Enovia V5 and Aras PLM\. I specialize in the end\-to\-end Engineering Change lifecycle: from impact assessment and cross\-functional stakeholder alignment, through BOM validation and product structure management, to final release per GE standards\. I've owned Tower Kit creation and release from scratch, created 130\+ manufacturing parts, and maintained a product structure of 80,000\+ function lines across change cycles\. What I bring: ▸ Engineering Change Management — ECO/ECR lifecycle, change control, zero\-defect release compliance ▸ PLM Tools — Enovia V5 \(expert\), Aras PLM \(proficient\), product structure & BOM management ▸ Configuration & Obsolescence Management — impact analysis, part lifecycle, GE Standards compliance ▸ Data & Quality — Six Sigma Green Belt, Tableau \(BI visualization\), Generative AI proficiency ▸ Collaboration — Change Coordinators, Design Engineers, System Integration Leads \(SILs\) I'm actively exploring PLM Engineer, Engineering Change Specialist, and Configuration Management roles in the energy, aerospace, industrial engineering, or engineering services sectors\.
