Who I am

Built for
complex systems

I'm a Senior DevOps & Platform Engineer with 8+ years operating mission-critical cloud-native infrastructure at enterprise scale — from real-time payment platforms at UBS Switzerland to global observability services at Oracle Cloud.

My work sits at the intersection of software engineering, infrastructure, and operations. I specialise in observability architecture, Kubernetes platforms, and SRE practices for high-availability systems in regulated environments.

I'm now based in Greece and available for senior remote B2B contracts worldwide — fintech, payment platforms, scaleups, and cloud-native engineering teams.

What I do

Services

Senior contractor engagements — remote, worldwide. I operate independently in complex, high-stakes environments. No hand-holding needed.

🔭
Observability & Telemetry Platform

End-to-end observability architecture for distributed and payment systems — from design to production. I build and operate the full stack: scalable telemetry ingestion pipelines, logs/metrics/traces across thousands of services, onboarding automation for new applications, and APIs that expose observability data to product teams. Strong track record in high-throughput, real-time financial environments.

Platform Engineering

Kubernetes platform design, operations, and automation for engineering teams at scale. Infrastructure as code, CI/CD pipelines, GitOps workflows, and cloud cost optimisation. I build internal developer platforms that reduce friction in onboarding, normal usage, and sunsetting of components — so product teams ship faster with less operational overhead.

🛡️
SRE & Reliability

SLI, SLO, and error budget design across distributed systems. Burn-rate alerting, incident response frameworks, postmortem culture, and on-call strategy. I embed monitoring and alerting best practices directly into platform teams — ensuring incidents are quickly detected, diagnosed, and resolved with minimal MTTR in regulated, high-availability environments.

Cloud Infrastructure & Integration

Multi-cloud infrastructure design, operations, and cost optimisation across Azure, AWS, and Oracle Cloud — including their native observability services. Event-driven architecture with Kafka, payment platform integrations, data pipeline design, and connectivity to European banking services (SEPA, Verification of Payee). Experienced in highly regulated financial environments.
