Summary

With a solid foundation in Laboratory systems and quality assurance, I have over five years of comprehensive experience in the food safety and microbiology field. Currently, I am a QA and group Microbiologist/Lab manager at Dursots/Alljoy in Johannesburg, where I manage and maintain robust quality management systems, ensuring compliance with ISO 9001:2015 and 17025 standards. My role involves implementing effective HACCP, GMP, and traceability programs, conducting internal audits, and driving regulatory compliance. I also oversee the plant's hygiene and microbiological safety, manage site pest control, lead serious incident investigations, and train laboratory technicians. Previously, I worked as a Microbiologist at Merieux Nutrisciences, where I honed my skills in aseptic techniques, sample management, and quality procedure compliance under ISO 17025 standards. My early career as a Lab Technician/Supervisor at SAI GLOBAL/QPRO further developed my expertise in laboratory management, non-conformance investigations, and staff supervision. My academic background includes a National Diploma in biotechnology from the University of Johannesburg and specialized training in ISO 17025:2017 and root cause analysis and 17025:2017 Laboratory systems course. My skills include excellent laboratory procedures, GMP and HACCP implementation, strong communication and leadership abilities, and proficiency in interpreting analytical and microbiological data. Experienced Microbiologist with proven experience improving scientific community by performing accurate research while complying with laboratory safety protocol and standards. Outstanding data management and report development skills contributing to research funding efforts.
