Professional Experience

Full-Stack Software Engineer

Portland General Electric

Aug 2024 – Present

Owned end-to-end delivery of a crew prediction web app from prototype to production, shipping a responsive, accessible Vite + React UI with AWS Amplify / Cognito authentication, Jenkins CI/CD, and integrated machine-learning predictions to improve outage response.
Built a data-dense operations dashboard with MUI DataGrid and DatePicker components, custom SCSS theming, and responsive layouts for crew dispatching, resource tracking, and real-time operational visibility.
Integrated AWS Location Services maps into the React UI for spatial crew tracking and dispatch visualization, connecting map layers to Cognito identity pools and backend geolocation APIs.
Enforced code quality through automated linting, Jest unit tests for React components, and AWS Lambda integration tests wired into Jenkins pipelines, catching bugs before they reached production.
Built a full-stack dispatcher upload tool — a React upload-button UI backed by a Lambda signed-URL workflow writing to S3 — reducing manual steps by 70% and saving ~30 minutes/day.
Architected AWS Lambda + API Gateway services that power Snowflake ETL pipelines, processing millions of rows every 15 minutes; delivered with CloudFormation and Snowflake Tasks/Pipes.
Led incident response to restore 1M+ deleted Snowflake rows within two hours, recovering data availability and minimizing operational impact.
Improved reliability and on-call readiness via CloudWatch dashboards/alarms, structured logging, and reusable Jenkins pipelines that reduced release risk across frontend and backend services.
Partnered with compliance and architecture teams to align Terraform modules, IAM guardrails, and Jenkins delivery workflows with SOX and FERC controls, providing traceable change history for audits.
Mentored two interns to ship an internal TV dashboard surfacing company KPIs from Snowflake and internal APIs; coached React component architecture, UI design principles, and deployment standards.
