I am a DevOps & Cloud Architect with 17+ years of experience in building scalable cloud infrastructure, automating deployments, and creating robust engineering platforms.
I specialize in:
- Cloud Architecture (GCP | AWS | Azure)
- Platform Engineering & Internal Developer Platforms
- Enterprise CI/CD using GitHub Actions
- Terraform, Kubernetes, GitOps, SRE
- Data Engineering (ETL, orchestration, quality, observability)
My mission is to improve developer experience, accelerate delivery, and build highly reliable, secure and automated engineering systems.
