QA/QC Quality Assurance Manager with 25+ years in PET/PTA and lab automation.
What I'm looking for
I’m a highly decisive QA/QC management professional with 25+ years of progressive experience in the petrochemical sector, specializing in both Polyethylene Terephthalate (PET) and Pure Terephthalic Acid (PTA) production. I lead complex laboratory operations while ensuring strong instrument calibration governance aligned with QSHE and ISO frameworks.
I’ve driven major facility and lab relocations—successfully integrating the PET laboratory into a unified PET/PTA laboratory with zero disruption, then executing a reverse relocation to support ownership transfer. I also run CAPA end-to-end, including technical root-cause investigations that stabilize product quality under real customer pressure.
I’m recognized nationally for Continuous Improvement and Quality Control Circles (QCC) leadership, serving as Secretary-General of the Focus Improvement Core Team and preparing corporate teams for national conventions. I’ve also been appointed as a Judge for the National Quality and Productivity Convention (TKMPN 2025).
Beyond governance, I modernize quality through digital lab automation—spearheading the Integrated Quality Control System (IQCS) architecture using ASP.NET Core and PostgreSQL, and building modules for automated lab data ingestion, gas management, and calibration scheduling. I’m also LRQA-certified as an Integrated Management System Auditor for ISO-9001, ISO-14001, and OHSAS 18001, and I bring that audit discipline into daily quality execution.
