What I'm looking for

I’m seeking a reputable organization where I can apply ISO 17025 quality leadership, validated analytical methods, and LIMS/equipment oversight to improve productivity, mentor teams, and make a sustainable contribution.

I’m a chemistry-focused professional committed to accurate, compliant laboratory work and continuous improvement. I bring a strong quality mindset grounded in ISO/IEC 17025 and proven performance in analytical chemistry environments.

Since 10/2023, I’ve led quality and technical execution as a Senior QC/QA Chemist, including the development and review of SOPs, validation and review of results against control samples, and auditing analytical procedures. I’m technically competent as an ISO 17025 nominated representative and technical signatory, ensuring documentation and technical records stay complete and audit-ready.

In my current role as a Chemist (03/2025–current), I manage daily laboratory operations to support smooth workflows, timely reporting, and adherence to quality standards. I also maintain and troubleshoot the Laboratory Information Management System (LIMS), oversee equipment performance and maintenance schedules, and coordinate internal quality reviews and corrective actions.

I work confidently across instrumentation and analytical methods—elemental analysis (ICP-OES, AAS, XRF), method validation, titration, digestion and sample preparation, and troubleshooting to protect data integrity. I mentor and train teams, represent the laboratory during audits and inspections, and drive efficiency and cost-saving opportunities while maintaining safety, SHER compliance, and environmental responsibility.
