Determination of critical process parameters (process optimization) and process window creation for injection molding processes (plastics), extrusion processes (PVC pipes), high frequency welding processes, ultrasonic welding processes. Sample size determination, critical dimension measuring and control during validation. Statistic control during all studies of validation (ES, OQ, PQ) and process implementation (with using Minitab). Monitoring of production processes, problem solving (RCA analysis, 5 why). Experience in working on production (start-up / shutdown / adjustment / repair of equipment). I was involved into transfer with next full installation and validation of semi automatic welding/assembling machine for production of urine / pleura / ostomy bags from Slovakia, England to Belarus plant. In sum it five transfers in different period of time. Experience in full cycle validation of production processes (FAT / SAT / ES / OQ / PQ). Creation and approval validation protocols and reports as per GDP. Was certified how Lean Six Sigma Green belt with creation and successful completion of production project.
