Senior DevOps & DBA Specialist with 25+ years of experience leading digital transformation of mission-critical environments. As a DevOps engineer, I design CI/CD pipelines using GitLab CI, Build, Test, SonarQube, and Nexus to automate deployment workflows. I virtualize infrastructure with VMware, Proxmox, and Docker, and orchestrate containers in Kubernetes — including migrating critical services from DCOS/Mesos to Kubernetes and integrating microservices such as Kafka, Elasticsearch, NiFi, and Graph. On the database side, I architect high-availability solutions using Oracle DataGuard, Oracle GoldenGate, and RMAN, achieving 99% availability while reducing operational costs. I have migrated large volumes of data (Oracle to MongoDB), ensuring integrity and consistency. Additional experience: Full-stack development (MERN/PERN stack) building MVPs and SaaS on AWS, GCP, Render, Vercel, and TiDBCloud.
-
Resilience and Reliability: I contributed to the design and implementation of cluster architectures that enabled the operations team to guarantee 99% availability for critical systems, improving end-user confidence.
-
Resource Optimization: Through a collaborative virtualization and automation effort, we helped the organization reduce its operating costs by more than 50%, allowing them to reinvest those resources in new initiatives.
-
Automation Culture: I facilitated the adoption of automation practices (scripts, N8N, CI/CD) that reduced the time spent on repetitive tasks by more than 80%, allowing the team to focus on projects with greater strategic impact.
-
Proactive Monitoring: I spearheaded the implementation of a proactive monitoring system that, by integrating development and operations needs, dramatically reduced incident detection and resolution time, improving the experience for both the team and users.
