Platform Engineer with an SRE mindset — I keep distributed systems alive at scale: 2.5M requests/s, without waking up at 3 am.

What I do

Reliable infra
as a craft.

Infrastructure & SRE

Multi-region bare-metal and cloud fleets managed with Ansible and Terraform. From day-1 provisioning to zero-downtime deploys — with SLOs, error budgets, and postmortem culture.

Observability

Full Prometheus / Thanos / Loki / Grafana stacks. Meaningful alerts, not noisy ones. On-call culture that doesn't burn out.

Kubernetes & GitOps

On-prem and cloud K8s at scale. Rancher, ArgoCD, and the discipline to keep everything reproducible and auditable.

Now

Senior Platform Engineer

Oct 2022 — Present · 3+ yrs

Global adtech platform. I own the reliability of a fleet serving 2.5M requests/second across EU, NA, and APAC — 4,500+ servers healthy, 30+ Kubernetes clusters running, and +50 TB of PostgreSQL humming — 24/7.

  • Fleet management: Ansible + Git (OVH / LeaseWeb / AWS)
  • Rancher + ArgoCD for on-prem K8s GitOps (~30 clusters)
  • Prometheus / Thanos / AlertManager / Oncall stack
  • Terraform on GCP (GKE, CloudSQL, GCS) and AWS (EKS, RDS, S3)
  • Confluent Kafka — KSQL, Schema Registry
  • Incident response, on-call rotation, postmortems

Web Architect

Sep 2020 — Jul 2022 · 2 yrs

Multi-cloud hosting provider serving digital agencies and e-commerce platforms. As Web Architect, I designed and operated a 700-server fleet across OVH, Scaleway, Vultr, and DigitalOcean — handling client traffic spikes, zero-downtime migrations between providers, and aggressive cost optimization across heterogeneous cloud environments.

  • Multi-provider Kubernetes cluster design and operations
  • Deep MariaDB performance tuning for high-traffic workloads
  • GitOps CI/CD pipelines for dozens of client environments
  • Zero-downtime live migrations across cloud providers
  • Infra sizing, cost optimization, and backup strategies
  • HAProxy load balancing and SSL termination at scale

Recipes

My personal cookbook — recipes I cook at home, because reliability isn't just for servers.

AI Enthusiast

AI-augmented
engineering.

I closely follow Anthropic's Claude releases and the broader AI ecosystem — new models, APIs, and tooling — to recommend solutions that are actually production-ready, not just hype.

Always current on Claude

I track every Anthropic release — models, APIs, Claude Code — and evaluate what's ready for real production use.

AI integrated into my workflows

From infra automation to code generation and smart tooling — I use AI where it genuinely reduces toil and improves reliability.

Best solutions for my clients

I recommend only battle-tested approaches — no buzzwords, just concrete AI leverage that delivers measurable value.
