About
Hi, I'm David.
I'm a Lead Platform and DevSecOps Engineer focused on modernizing CI/CD pipelines and scaling cloud infrastructure for regulated, high-stakes environments. My recent work centers on migrating legacy stateful systems to modern Kubernetes microservices and building heavy automation with Python and enterprise Terraform. I use AI engineering co-pilots to cut manual toil and accelerate deployment cycles for my teams.

Experience
- Owned platform engineering across two teams simultaneously, provisioning and maintaining infrastructure across 240+ repositories and 100+ Kubernetes namespaces in a Fortune 500 financial services environment.
- Standardized reusable Harness CI/CD pipeline-as-code templates across the organization, migrating 34 repositories from Bitbucket to Harness and establishing consistent code-promotion practices.
- Owned release management end-to-end, orchestrating Blue/Green production deployments and managing AWS Auto Scaling Groups and load balancers for zero-downtime cutovers across 383+ deployments.
- Built Python automation to handle Git operations, branch checkout, and image patching across the fleet, cutting a multi-day enterprise patching cycle down to hours.
- Acted as the primary PR gatekeeper for software supply chain security, enforcing SonarQube and Checkmarx SAST quality gates before code reached the artifact registry.
- Integrated HashiCorp Vault for dynamic secret injection across the CI/CD pipeline, eliminating hardcoded credentials.
- Diagnosed a JKS trust store certificate issue causing silent Kubernetes deployment failures across the org, and coordinated the fix via Helm chart and base-image updates.
- Coached engineering teams on CI/CD pipeline design, cloud migration, and DevOps best practices across the organization.
- Designed and delivered cloud migration training, accelerating team readiness and reducing operational risk during AWS transitions.
- Mentored engineers on Kubernetes, automation, and cloud-native operations, building internal platform capability.
- Built CI/CD pipelines from scratch using TeamCity and Octopus Deploy, establishing the team’s release engineering foundation.
- Automated deployment processes using PowerShell, eliminating manual steps and reducing release cycle time.
- Diagnosed and resolved application errors for ASP.NET MVC web applications, reducing downtime and improving system reliability.
