Observability Architect | APM | DevOps | Cloud
About Me
I am an Observability Architect and APM Expert with over 18 years of IT experience, including 6 years specializing in Observability, Monitoring, and Application Performance. I have expertise in migrating APM solutions such as Dynatrace, Splunk Observability, and AppDynamics, as well as instrumentation using OpenTelemetry. I support large organizations in implementing supervision strategies, IT audits, crisis management, and DevOps automation across hybrid and multi-cloud environments.
As a technical expert and educator focused on continuous improvement, I design resilient and scalable monitoring architectures aligned with business performance and visibility goals. My skills span observability platforms, cloud technologies, containerization, DevOps pipelines, and web performance analysis.
I have hands-on experience with AWS services, Kubernetes, Docker, and OpenShift, and I am proficient in CI/CD tools like GitLab, Jenkins, Ansible, and Terraform. I am also skilled in database management, programming languages including Python, JavaScript, Java, and PHP, and agile methodologies.
Throughout my career, I have led complex migrations, automated deployments, and developed dashboards and alerting systems to enhance application monitoring and performance. I collaborate closely with technical leads, architects, and product managers to drive continuous improvements and ensure operational excellence.
I am passionate about sharing knowledge and have conducted internal training sessions to improve documentation and governance practices. My certifications include AWS Certified DevOps Engineer – Professional and multiple Splunk certifications, reflecting my commitment to staying current with industry standards and technologies.
