What I'm looking for

I’m looking for a role where I can lead Quality Control and analytical method validation, strengthen ISO 17025 and GLP compliance, and drive regulatory submissions, while improving operational efficiency, data integrity, and team performance.

I’m a Senior Chemist with a proven track record directing and coordinating Quality Control laboratories. I specialize in comprehensive quality management across agrochemical, pharmaceutical, food, and packaging sectors, with deep experience implementing and auditing ISO 17025:2017 and Good Laboratory Practices (GLP).

I focus on operational excellence, regulatory compliance, and analytical rigor—successfully increasing delivery compliance from 85% to 93% by improving workflows and technical supervision. I lead QC processes for raw materials and finished products, develop and validate analytical methods (including HPLC/GC/ICP-OES), manage regulatory registrations before the ICA, and design stability studies in line with international guidelines (USP, ICH, CICTA), while supervising technical staff and laboratory quality systems.
