I’m a highly skilled and certified DevOps engineer with 13 years of experience delivering secure, scalable, and automated infrastructure for organizations across the globe. I specialize in Microsoft Azure and Kubernetes, but my expertise spans the entire DevOps toolchain, cloud ecosystems, development, and operating systems. I hold the following certifications: - Microsoft Certified: Azure Solutions Architect Expert (AZ-104, AZ-400, AZ-305) - Certified Kubernetes Administrator (CKA) - Certified Kubernetes Security Specialist (CKS) - Currently working toward Cisco CCNA I’ve worked with clients across industries including finance, blockchain, healthcare, oil and gas, identity and access management, and so on. My project experience ranges from small agile teams of 5 to enterprise-scale initiatives involving 500+ people. I’ve served as both a solo DevOps engineer and a team lead, guiding DevOps teams through high-stakes migrations, greenfield builds, and modernization projects. I’ve successfully delivered projects across time zones ranging from Australia and the Philippines to the US and Europe. I’m fully at ease with distributed teams, shifting schedules, and asynchronous collaboration. Tight deadlines, off-hours work, and complex coordination don’t intimidate me—they’re part of the job, and I handle them with focus and reliability.. Before moving into DevOps, I worked in forensic data recovery as a QA engineer, gaining a deep understanding of data integrity, validation, and analysis under pressure. I also have a strong background in JavaScript and TypeScript development, having worked on frontend and backend tools—both developing new systems and refactoring legacy code. I’m a Linux enthusiast and advocate, passionate about free software and open-source ecosystems. Outside of work, I regularly attend cybersecurity, privacy, and hacking conferences. I’m deeply committed to cybersecurity and digital privacy, and I actively stay updated with trends and vulnerabilities in the field. I also conduct knowledge transfer sessions, tutor colleagues, and help teams adopt DevOps best practices and modern workflows. Key technologies and skills include: - Cloud & infrastructure: Azure (App Services, VMs, AKS, Key Vault, Storage, Networking, Logic Apps, AAD, SQL, PostgreSQL, Backups, Site Recovery, Application Insights, Security Center, Governance, Cost Optimization) - Infrastructure as Code & automation: Terraform, Bicep, ARM, Ansible, Chef, PowerShell DSC, Bash, PowerShell - CI/CD & GitOps: Azure DevOps, GitHub Actions, GitLab CI, TFS, Flux, ArgoCD - Containers & orchestration: Docker, Kubernetes (AKS & self-hosted) - Monitoring & observability: ELK Stack, Datadog, New Relic, Grafana - Messaging systems: RabbitMQ, Azure Service Bus, Microsoft Service Bus - Databases: MSSQL, PostgreSQL, MySQL, MongoDB - Testing & QA: JMeter, Selenium WebDriver, Puppeteer - Programming: JavaScript, TypeScript, Node.js - Sysadmin & support: Linux and Windows administration, with extensive 24/7 production support experience If you're looking for someone who can deliver solid infrastructure, automation, and DevSecOps from both a technical and strategic standpoint — while collaborating effectively across teams and time zones — I’m ready to help!
