Led a team of machine operators and process mechanics, planned staffing across both areas and kept output, delivery dates and quality on schedule.

Accompanied audits, guided auditors through production and kept processes and documentation compliant.

Stayed hands-on: set up and optimised moulding and welding processes, handled mould changes and sampling, and solved process, machine and mould issues.

Onboarded and trained new employees and made sure safety and workplace standards were met.

Set up, operated and monitored injection moulding machines and peripheral equipment; installed and changed moulds, sampled new moulds and optimised process parameters for consistent quality and efficient cycle times.
