Work History

Production Quality Engineer

Northvolt ETT
Skellefteå
10.2022 - Current
  • I developed the in-line quality measurements of scanning beta gauges in the process using Six Sigma tools (8D problem solving), with process capabilities analysis, and poke-yoke.
  • I participated in FMEA risk mitigation and developed control plans with special characteristics (SC and CC) built from customer-specific requirements, regulatory bodies, and internal risk assessments.
  • The continuous flow quality of cells was monitored through the charge and discharge processes, alternating current internal resistance (ACIR), direct current internal resistance (DCIR), open circuit voltage (OCV), and capacity checks.
  • I trained the operations and quality teams with the Statistical Process Control (SPC) system to monitor and control the process variations that led to an increase in quality efficiency and a decrease in the waste/scrap rate.
  • Developed and implemented comprehensive reaction plans in different processes, resulting in a 25% reduction in product defects and a 15% reduction in the scrap rate, which leads to customer satisfaction.
  • Contributed to the initiation and execution of Layer Process Audits (LPA), resulting in a 20% reduction in recurring defects, and improved process efficiency.
  • From the reported deficiencies, standard operating procedures (SOP), control plans, sampling plans, work instructions, and quality documentation were developed.
  • My responsibilities included in all stages of lithium-ion battery cell production, from slurry mixing to cell wrapping.

Mechanical Design Engineering Intern

Azad Engineering Pvt.Ltd
Hyderabad
07.2017 - 07.2018
  • I was involved in product development and manufacturing.
  • I designed parts for heavy-duty gas turbines and critical aircraft engines.
  • I worked on projects including Design for Assembly (DFA), manufacturing (DFM), and the Bill of Materials (BOM) based on the product requirements and risk assessments to optimize product designs for manufacturability.
  • I participated in the development of technical design documentation (TDD) with product specifications, test plans, component properties, process characteristics, and operational requirements.
  • Collaborated with cross-functional teams to analyze customer-specific requirements (CSR) and developed design estimates by discussing cost-effective measures.
  • Participated in supplier discussions to identify cost-effective, reliable materials, and components.
  • Gained knowledge about the ISO 9001 standard for quality management throughout the product life cycle.
