01 / Selected work

Engineering with an outcome.

Selected experience in shared platforms, delivery, and reliability. Outcomes below are drawn from my résumé.

01 / CLOUD PLATFORMCITI

A platform that scales
with the teams behind it.

Operate EKS fleets across production, staging, and ephemeral environments, with shared standards for networking, storage, RBAC, upgrades, and autoscaling.

200+microservices supported
AWS EKSTerraformArgo CDKEDA
Engineering approach

Evolve multi-account AWS architecture using VPCs, subnets, Transit Gateway, Direct Connect, and IAM. Standardize infrastructure with reusable Terraform and CloudFormation modules, and deliver changes through GitOps workflows.

02 / RELIABILITYCITI

Turn incident lessons
into lasting improvements.

Define SLOs and observability standards, lead on-call response, and drive post-incident reviews toward systemic fixes across the platform.

Engineering approach

Combine metrics, logs, and distributed tracing to investigate production issues. Partner across engineering and security to improve alerting, runbooks, and platform standards. These changes also reduced P1 incidents by 35%.

03 / DEVELOPER EXPERIENCEIBM · SEVONE

Less delivery friction.
More engineering momentum.

Build AWS infrastructure and CI/CD pipelines for 50+ engineers, with promotion gates, rollback procedures, and consistent artifact governance.

−45%deployment failures

Engineering approach

Establish Docker image promotion standards and Artifactory governance. Build self-service test infrastructure and automation in Go, Python, and Groovy. Reduce onboarding time by 40% and manual environment setup by 60%.

02 / Experience

Built in complex
environments.

From financial services to infrastructure software, I focus on dependable systems and practical automation.
