Build and maintain automated deployment pipelines (CI/CD) targeting AWS infrastructure utilizing containerized ecosystems (Docker, Amazon ECS/EKS) and Infrastructure as Code (Terraform).

Enterprise Security & Compliance

Configure robust authentication and authorization layers leveraging Spring Security alongside modern protocols (OAuth2, OIDC) to ensure strict compliance with insurance data regulations (HIPAA, SOC 2, or PCI-DSS).

Performance Tuning & Monitoring

Proactively profile application components to eliminate frontend bottlenecks, optimize backend execution paths, and tune slow database queries using AWS CloudWatch or APM tools.

Distributed Team Leadership

Drive technical alignment across a 100% remote engineering team, mentor mid-level developers, and partner closely with Insurance Product Owners to turn business logic into scalable code.
