Hey, I'm Nik 👋

Senior DevOps / SRE Engineer with 8+ years of experience building and operating infrastructure across Web3, DeFi, Banking, ML/AI, and Enterprise environments. I've worked at Lido (Ethereum liquid staking), Mobilize Financial Services, and across cybersecurity and telecom sectors.

🧱 What I do

From bare-metal Kubernetes clusters to multi-cloud deployments, I design infrastructure that's resilient, scalable, and secure. I specialize in automating everything — from provisioning and configuration management to CI/CD pipelines and incident response. I've built and maintained high-availability systems handling real financial value, where downtime isn't an option.

My work spans the full infrastructure lifecycle: architecture design, IaC, observability, capacity planning, and on-call ownership. I've scaled systems for 100+ member engineering teams, dockerized 100+ applications, managed hundreds of GCP resources via Terraform, and operated 300+ Linux servers in production. I thrive in environments that move fast and demand operational excellence.
