I am an AWS Cloud Architect with extensive hands-on experience designing secure, scalable platforms for enterprise clients in banking, automotive, public sector, and research. I have delivered multi-AZ AWS architectures with VPC segmentation, IAM governance, encrypted data layers, ECS/Fargate workloads, Aurora PostgreSQL, Route 53 failover, and full observability with CloudWatch, CloudTrail, and GuardDuty. I also drive Infrastructure-as-Code practices (Terraform, CloudFormation) and automation using Python, Bash, CodePipeline, and CodeBuild. I’ve worked on platform modernization and data integration using AWS Glue, Lake Formation, and S3 data zones, with governance and ingestion environments across regulated contexts. I collaborate closely with product owners, developers, and stakeholders to translate requirements into robust, secure architectures that emphasize compliance, resilience, and cost efficiency. My focus is building reliable cloud foundations that enable teams to deliver applications at scale. I routinely partner with cross-functional teams across international projects, ensuring secure, auditable deployments and end-to-end observability. I’ve also supported hybrid backends leveraging Windows and AD ecosystems when needed, and I bring a practical mindset for operational automation and governance that helps organizations move faster while reducing risk.
