Researcher specializing in surface engineering and tribology with a PhD in Mechanical Engineering (University of Coimbra, 2020). Extensive experience at utilizing magnetron sputtering for deposition of self-lubricating thin films. Proven expertise in microstructural, mechanical, and tribological characterization of these films. Provides valuable services in tribological characterization for external clients. Actively supervises MSc students in their research endeavors. Previously held the position of Process Engineer at Tikves Winery (Aug 2014 - Aug 2015), where I successfully implemented lean manufacturing principles and managed resources at bottling stations. Ensured consistent quality of raw materials, semi-products, and final products through meticulous control. Maintained optimal process parameters and performed preventive maintenance on bottling equipment. My academic background includes a Joint European Master Program in Tribology of Surfaces and Interfaces (Lulea University of Technology, 2015-2017) and a Bachelor of Science degree in Mechanical Engineering (University “Ss. Cyril and Methodius”, 2009-2013) with a focus on automotive engineering. Highly proficient in various thin film deposition techniques, particularly magnetron sputtering. Possess in-depth knowledge of material characterization tools like SEM, XRD, XPS, and AFM. Experienced in conducting tribological testing using diverse equipment (SRV, pin-on-disk). Fluent in English, Macedonian, and Portuguese with working knowledge of Serbian-Croatian and Bulgarian. Confident user of Microsoft Office Suite and engineering software (AutoCAD, Inventor, OriginPro, Matlab). Actively contributes to the scientific community by authoring and co-authoring publications in prestigious journals like Surface and Coatings Technologies, Tribology International and Applied Surface Science. Regularly participate in peer review activities for renowned pjournal. Disseminated research findings at international conferences (ECOTRIB 2019, Leeds-Lyon Symposium of Tribology, International Conference on Metallurgical Coatings and Thin Films (ICMCTF).
