Experience
Led comprehensive cloud infrastructure optimization initiatives, achieving a 60% reduction in monthly costs through strategic redesign and implementation of AWS CDK-based deployment tooling. Spearheaded the development of a new CI/CD pipeline incorporating OCI initiatives for Helm Packages and Docker images, while creating an ArgoCD GitHub action for enhanced sync and commit tracking. Implemented robust security measures including 1Password secret automation with environment-specific dotenv templates, Passkey authentication, and IRSA/assume-role based authentication. Successfully renegotiated contracts to optimize SaaS tooling spend across DataDog, AWS, and Customer.io. Enhanced EKS cluster performance through strategic configuration improvements, version upgrades, and Karpenter optimizations for node sizing, while strengthening security posture via LinkerD/Traefik network traffic hardening.
Provided expert infrastructure engineering and architectural consulting services for cloud-hosted systems, with a focus on infrastructure as code implementation using Terraform (OpenTofu), CDK, and Pulumi. Led Kubernetes cluster upgrades and configuration optimizations to align with industry best practices and latest releases. Delivered comprehensive development consultation and engineering support while mentoring junior developers and those transitioning into tech, leveraging modern LLM and IDE tools to enhance learning outcomes.
Led infrastructure and developer experience initiatives as Tech Lead at a Web3/crypto startup, driving a transformative migration from monolithic to microservice architecture. Implemented AWS and Kubernetes-based declarative operations, resulting in enhanced engineering velocity and streamlined developer workflows. This architectural evolution significantly reduced the time-to-contribution for engineering teams while establishing robust, scalable infrastructure foundations.
Led the creation and migration of a new multi-AWS account environment, successfully transferring over 15 microservices and 8 databases while enabling multi-region failover, reducing resource costs, and enhancing security posture. As infrastructure point-of-contact, participated in cross-team design sessions and authored extensive infrastructure-as-code using Terraform and Helm for AWS infrastructure and Kubernetes clusters. Implemented CI/CD pipelines using GitHub Actions and Spacelift for automated infrastructure deployments, while planning network CIDRs with consideration for future expansion. Enhanced application deployments and database migrations through ArgoCD and Kustomize implementation in EKS clusters, and integrated Teleport and Okta SSO for secure access to RDS databases and EKS clusters, significantly reducing new developer onboarding time.
Led technical infrastructure initiatives as the technical lead for application infrastructure, driving a successful migration to a new multi-account structure. Architected and implemented Azure infrastructure using TerraGrunt and Terraform, establishing a well-documented and maintainable infrastructure codebase across the engineering organization. Developed comprehensive Ansible automation scripts for VM management, significantly reducing manual tasks and engineering toil. Guided teams in adopting the new Azure infrastructure, resulting in improved deployment times and enhanced application uptime. Created and tested a reusable VM Terraform module that optimized build agent performance and reduced operational overhead.
Architected and implemented comprehensive CI/CD infrastructure, including Kubernetes-based Jenkins build agents and migration from Nexus to Artifactory JFrog. Led the design and execution of CI/CD workflow migrations for company acquisitions while establishing robust Jenkins automation with Bitbucket On-Prem integration. Developed Python-based automation solutions for Jenkins system maintenance, including patch management and recovery procedures. Spearheaded DevOps knowledge sharing initiatives, providing comprehensive training and documentation for build system integration using Gradle, Maven, CMake, Conan, and Ninja, fostering team-wide adoption of modern DevOps practices.
Developed and implemented a custom web-based monitoring solution for Nagios alerts, enhancing visibility and management of critical system events. Managed comprehensive production system maintenance, including patch management, optimization, and routine maintenance procedures. Implemented automated Bash scripting solutions for system self-healing and core file analysis, significantly reducing manual intervention during system crashes. Led debugging efforts for overnight batch processing systems, ensuring reliable production operations and minimal downtime.
Collaborated with on-site teams to remotely configure and deploy network infrastructure while providing comprehensive monitoring and troubleshooting support for customer installations. Implemented efficient triage processes for network equipment issues, ensuring rapid resolution of customer-reported problems. Leveraged remote collaboration tools to maintain seamless communication with local teams while delivering high-quality technical support and network optimization services.
