At Openplay Ltd, I designed and maintained Kubernetes infrastructure for an enterprise SaaS platform handling about 500M monthly requests with a 99.98% SLA. I worked with AWS EKS, Terraform, and production workloads.

I also operated observability and incident-response systems using Datadog, Prometheus, Grafana, and CloudWatch. I investigated production incidents and implemented long-term reliability improvements.

Earlier at Openplay Ltd, I led the containerization and Kubernetes migration of a large Laravel project, and developed backend services and APIs with a focus on scalability and performance.

My earlier work included leading development for Exit Bee's platform serving 50M+ monthly visitors, building REST APIs and tooling at Draxis S.A, and developing web applications at Onlinepizza / Delivery Hero Group and Tessera Multimedia.
