The technology matters, but it is only part of the record. This layer combines formal learning with observations from people who saw the work up close.
Education
Along side my formal studies in programming and law, I invested heavily in modern IT disciplines. I completed an intensive QA program in Silicon Valley, California, focused on manual and automation testing with extensive labs, projects, and real-world practice. I also earned certifications in DevOps Foundations: Continuous Delivery/Continuous Integration (LinkedIn, 2025), and regularly study advanced technical courses on Pluralsight, Udemy, and LinkedIn Learning.
These experiences extend my education beyond traditional degrees, giving me a solid foundation in QA engineering, automation, and DevOps practices. Combined with extensive experience in IT operations, system administration, and cloud infrastructure, this ensures I bring not just theory, but proven, professional-level expertise to every project.
