At Rynith, I architect and operate GCP infrastructure for a multi-tenant SaaS platform processing 150K+ customer reviews each month. I provision GKE, Cloud Run, and Pub/Sub infrastructure through Terraform and maintain zero-downtime CI/CD pipelines with automated rollback.

I build secure, observable production platforms using Kubernetes, Terraform, AWS, GCP, Prometheus, Grafana, and ELK. My work has supported 30+ third-party integrations at a 99.9% uptime SLA while enforcing GDPR controls through IAM, Secret Manager, and VPC hardening.

Previously at Craftmerce and SaluBata, I improved deployment frequency by 40%, halved deployment times, increased delivery velocity by 60%, and cut provisioning time by 50%. I also reduced cloud carbon emissions by 28% and costs by 25% through workload right-sizing.

Before focusing on DevOps, I spent five years building software and microservices, including Node.js and Express services handling 20K+ RPM. I communicate infrastructure trade-offs clearly with founders, product, and QA teams, and am available for remote contracts or full-time work with English-first teams.
