Designed and implemented scalable cloud infrastructure to support AI agent

• • frameworks, configuring custom skills that enabled LLMs to interact safely and efficiently with internal corporate systems via Model Context Protocol (MCP). Architected robust Data Platform infrastructure, automating provisioning and hardening of AWS Bedrock and SageMaker environments via IaC to guarantee strict privacy, seamless data pipeline anonymity, and data compliance. Established comprehensive AWS Security Governance and automated workflows for continuous CVE remediation to significantly reduce security risk and preparation effort for corporate ISO compliance audits. Deployed and administered Langfuse infrastructure to provide engineering teams with robust LLM observability, tracing, and prompt management, significantly improving cost tracking and model performance tracking. Migrated high-throughput data pipelines from Amazon RDS to ClickHouse, optimizing data workflow performance and horizontal scalability. Led the migration from a monolithic Terraform repository to Terragrunt, drastically enhancing environment isolation, code modularity, and team velocity. Standardized application continuous delivery by transitioning workloads from AWS CodePipeline to ArgoCD and GitHub Actions; migrated from NGINX Ingress to Envoy Gateway API to modernise platform networking.

Established enterprise Kubernetes platforms natively based on Rancher RKE, and

• • successfully orchestrated the subsequent migration of 100% of production workloads into Amazon EKS clusters. Fully automated end-to-end cluster provisioning and internal application lifecycle management using an advanced declarative GitOps layer built on Terraform and ArgoCD. Transitioned 100% of unautomated legacy infrastructure into clean, maintainable Terraform Enterprise codebases, establishing robust CI/CD by blending Jenkins pipelines with ArgoCD. Optimized cloud compute spend by engineering custom strategies to integrate AWS Reserved Instances and Spot Instances safely into high-availability production environments. Configured advanced cluster networking and access controls utilizing Calico network policies to guarantee secure multi-tenant isolation.
