Over Nikola
Expert IT Engineer | Systems Architect | DevOps Strategist
20+ years’ experience delivering scalable, secure, and high-availability solutions across banking, cloud, media & enterprise-grade platforms.
🚀 From leading CI/CD infrastructure for financial institutions to architecting fault-tolerant systems on IBM Cloud and Dockerized environments, I specialize in bridging application delivery with infrastructure excellence. I possess deep technical expertise in Linux and Windows systems, automation (Ansible, Bash, Python), cloud technology (AWS, Azure, OpenStack), container ecosystems (Docker, Kubernetes), and secure messaging (RabbitMQ, WebSphere MQ, ActiveMQ).
✔️ Notable achievements:
• Migrated core banking applications at Van Lanschot Kempen (full stack: OS–App–CI/CD)
• Delivered scalable DevOps pipelines (Azure DevOps, Git, Jenkins)
• Architected HA environments and performed mission-critical upgrades (e.g., F5 LTM, VMware, Puppet/Ansible orchestration)
• Supported VIP clients at Netflix & IBM Cloud, with 24/7 service reliability mindset
🎯 My focus: High-impact engineering delivery, infrastructure modernization, automation, and solving the “unsolvable”. Available for both project execution and long-term partnerships.
📩 Let’s talk if you need a senior-level technologist to lead or rescue your infrastructure, accelerate DevOps maturity, or unlock full-system visibility and resilience.
