Replatforming a legacy SaaS platform to AWS and Kubernetes

Situation

The system and the situation

An established enterprise SaaS platform was operating in a self-managed colocated environment. The organization needed a more maintainable infrastructure foundation while continuing to support active production workloads and ongoing product delivery.

Constraints

What the work had to respect

• The platform was already supporting active customers and business operations.
• Modernization could not assume a clean-sheet rewrite.
• Product delivery and operational support had to continue during the migration.
• Infrastructure, application behavior, deployment processes, networking, observability, and security were interconnected.
• The internal team needed to understand and operate the resulting environment.

Technical work

How the work moved forward

• Contributed to AWS architecture and Amazon EKS platform design within the broader migration.
• Implemented Terraform-based infrastructure automation and Kubernetes deployment practices.
• Worked across networking and connectivity, CI/CD modernization, observability, and production troubleshooting.
• Contributed to backend and platform changes required by the migration, along with documentation and team knowledge transfer.

Result

What changed

The organization transitioned production infrastructure to AWS and Kubernetes while maintaining continuity for active operations. The work created a stronger foundation for repeatable deployment, infrastructure ownership, observability, reliability, and continued platform modernization.
