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.

IT Systems Operations Engineer
Over the course of my career, I have built a deep and well-rounded foundation in IT operations, system administration, infrastructure engineering, and cloud integration, combining technical expertise with practical problem-solving. My professional path has taken me through organizations of all sizes — from agile startups and high-growth technology firms to large-scale, globally distributed enterprises — where I have planned, implemented, and maintained mission-critical systems that directly support core business functions.
I have successfully led high-impact infrastructure transitions, including cloud migrations, data center consolidations, enterprise network upgrades, and hybrid environment integrations, ensuring minimal downtime and smooth adoption across teams. My work spans Windows, macOS, and Linux platforms, with hands-on experience in AWS, Microsoft Azure, VMware, Docker, Kubernetes, and infrastructure-as-code solutions such as Terraform and Ansible. I have collaborated closely with development, security, and business stakeholders, bridging the gap between technical requirements and organizational objectives while ensuring compliance with security frameworks and best practices.
In every role, I bring a solutions-focused approach centered on reliability, performance optimization, and security hardening. This includes implementing proactive monitoring with tools like Prometheus, Grafana, and CloudWatch; refining CI/CD pipelines with GitHub Actions and Jenkins; enforcing identity and access controls through SSO, IAM, and Active Directory; and establishing governance policies that support long-term operational efficiency. I have a proven ability to troubleshoot complex technical issues, design resilient architectures, and optimize cloud resources for cost-effectiveness while maintaining a secure, well-maintained environment.
Beyond day-to-day operations, I actively contribute to modernization efforts — introducing automation to reduce manual workloads, codifying infrastructure for repeatable deployments, and improving disaster recovery and business continuity plans. Whether supporting end users, advising on technical strategy, or leading infrastructure upgrades, my consistent priority is enabling teams to work faster, smarter, and more securely while aligning technology with organizational goals.
