Brandon Foster πŸ‘‹

Senior DevOps Engineer | AWS, Kubernetes, Terraform | Platform & Infrastructure Leadership

GitHub LinkedIn Location Email

Designing, scaling, and operating reliable, secure, and cost-efficient cloud platforms β€” while building practical, local-first autonomous AI agents to automate real-world workflows.


πŸ’‘ About Me

I am a Senior DevOps Engineer with over a decade of experience designing, scaling, and operating cloud-native platforms in production environments. My focus is on building reliable, secure, and cost-efficient infrastructure that enables engineering teams to move quickly without sacrificing stability or governance.

I specialize in AWS-based platforms, Infrastructure as Code (Terraform), Kubernetes, and CI/CD systems, with deep experience supporting large microservice architectures and data-intensive platforms. Beyond hands-on engineering, I routinely act as a technical leader and mentorβ€”guiding developers and DevOps engineers in modern DevSecOps practices, platform reliability, and operational excellence.

When I'm not architecting cloud platforms, I engineer local-first AI agents and developer tooling to automate everyday tasks and monitor AI coding workflows.

πŸ’Ό Career Highlights & Key Achievements

  • Large-Scale Cloud & Kubernetes Migrations:
    • Led migration of 30+ microservices from ECS to EKS, leveraging ArgoCD for declarative GitOps delivery, improved orchestration, and auto-scaling.
    • Consolidated multi-account AWS and EKS acquisition workloads into unified, secure cloud architectures.
    • Migrated legacy Ansible + EC2 workloads to containerized EKS applications.
  • Enterprise CI/CD & Developer Velocity:
    • Led migration of 100+ repositories from Bitbucket to GitHub & GitHub Actions, standardizing CI/CD pipelines and boosting build reliability and developer velocity.
    • Managed scalable CI environments supporting thousands of Linux-based build containers.
  • Infrastructure as Code & Platform Engineering:
    • Designed and authored reusable, enterprise-grade Terraform modules managing Snowflake, Datadog, Confluent Cloud, Databricks, GitHub, and AWS resources at scale.
    • Standardized AWS multi-region environments using Terraform and AWS CloudFormation.
    • Led migration from AWS MSK to Confluent Cloud, reducing operational complexity and cost while improving Terraform automation.
  • Security, Observability & FinOps:
    • Architected AWS App Mesh to enforce mTLS service-to-service communication across ~30 microservices.
    • Centralized secrets management architectures to enhance zero-trust security posture.
    • Implemented 24/7 observability and monitoring across AWS and Kubernetes using Prometheus, Datadog, CloudWatch, Grafana, Loki, and Fluent Bit.
    • Drove cloud cost-optimization initiatives saving $10K+/month within two months through architectural optimization and vendor rationalization.

πŸš€ Featured Personal Projects
