Hi, I’m Mat Leszkiewicz, a Support Engineer at n8n since June 2026. My background spans computer science, software support, and DevOps, with a continuing interest in how systems work and how they can be secured.
I completed a Higher Diploma in Computer Science at South East Technological University. Before joining n8n, I worked in product and technical support at Intercom and completed a software developer internship in FundRecs’ DevOps department, where I worked on AWS CI/CD pipelines and infrastructure. Earlier roles at TikTok and Accenture focused on model optimization and content moderation.
My technical experience includes Python, Java, JavaScript, AWS, Elasticsearch, Git, and Docker. I continue to develop my knowledge of cybersecurity, threat intelligence, and Security Operations Center (SOC) practices alongside my work in support engineering.
Outside work, I enjoy hiking, traveling, and learning about psychology and social engineering. You can find more about my background on my CV and read about my projects.
