About

Backend-leaning full-stack engineer from Valcom who maintained Django/PostgreSQL services for mass-notification/paging servers used by education/commercial/government customers. Notable for hardening authentication and reliability (JWT refresh + rotation tokens, WebSockets/EventStream) and for modernizing a legacy Ext.js/PHP stack into a React + Django architecture with strong CI/testing and production incident ownership.

Key Strengths

  • Built and stabilized JWT auth flows (refresh + rotation tokens) to reduce 401s and sync issues
  • Diagnosed and mitigated production performance incidents caused by runaway client retries (prevented log/CPU flooding)
  • Improved automated test coverage for Django REST APIs using Pytest integrated with GitLab CI/CD
  • Modernized legacy front-end from Ext.js to React SPA (hooks, Redux, React Router) with improved maintainability
  • Strong debugging/triage using system logs (Nginx/Apache), CI pipeline logs, and browser network tooling
  • Designed PostgreSQL views/queries to offload computation from app layer and support sortable UI displays
  • Disciplined engineering practices: narrow-scope commits, issue tracking, rapid patch releases, collaborative troubleshooting

“Frontend engineer/lead focused on scalable architecture and reusable UI platforms: built a schema-driven, IoC-based unified filtering system across an app with feature-flagged rollout and strong TypeScript/testing discipline. Also created a standalone React NPS survey package that works across microfrontends (handling peer dependency/version issues) and implemented accessibility improvements for complex interactions like drag-and-drop while leading an Atomic Design → Feature-Sliced Design migration.”
