Ruby on Rails · Java / Spring Boot · Node.js / NestJS · React · Angular
Built a React/Redux investigation tool that brings meeting transcripts, highlights, database events and cloud logs into one workflow.
Connected evidence by meeting ID, developed APIs for date-filtered logs and event histories, and added live-meeting model testing and audio uploads for model training. Developed Java, Ruby and Node.js/NestJS microservices for meeting-intelligence and transcription workflows.
Worked with Angular to integrate Vidcast administration into Cisco’s platform, including organization and user retention policies.
Built administration workflows and REST API integrations, worked on Redis caching, and used Grafana to investigate production behaviour.
Developed Rails APIs, modernized notifications with Angular, and improved reporting and integrations in a production fleet-management platform.
Led remediation of critical and high-severity scan findings, implemented an OAuth 2.0 Slack integration, improved scheduled reporting, and developed KML import/export pipelines.
