DevOps & Cloud Engineer

Building resilient, secure infrastructure for critical systems.

DevOps & Cloud Engineer with 19+ years leading high-reliability national grid operations. I design and deliver production-grade CI/CD, cloud-native platforms, and ML-driven systems that improve uptime, security, and operational decision-making.

About me

Operational experience.
Engineering-forward delivery.

I am Samuel Peter, a DevOps and Cloud Engineer with more than 19 years of experience as Principal Manager in critical national power-grid infrastructure. My background combines real-time grid operations, incident response, and high-availability systems with modern cloud, automation, and data-driven delivery.

I build solutions that are production-ready and operationally grounded — whether designing contract-first microservices, implementing enterprise CI/CD, or deploying ML recommender systems for asset risk prioritization on AWS. Every project prioritizes reliability, security, maintainability, and measurable outcomes.

API design · OpenAPI · k6

Why contract-first APIs help teams move with confidence

Starting with an explicit API contract creates a shared agreement between consumers and services. Pairing that contract with automated tests and repeatable load checks makes changes easier to validate. For this project, document the test strategy, service boundaries, and measured performance results.

CI/CD · Quality gates

From commit to confidence: a layered pipeline

A dependable pipeline makes quality visible: build with Maven, run unit tests, exercise user flows with Selenium, and automate delivery through Jenkins or GitHub Actions. The strongest case study will show pipeline stages, failure handling, and evidence from actual runs.

Turning asset-risk signals into useful maintenance recommendations

ML becomes operationally valuable when its outputs are explainable, timely, and integrated into a team's workflow. Describe the data assumptions, model evaluation, API deployment, container strategy, and safeguards against treating recommendations as unquestionable decisions.
