Full-stack engineer building production streaming platforms and real-time services, including a multi-tenant live video platform.

Venezuela

Message

I built and operated a multi-tenant live video streaming platform as its sole engineer. I created its React/Redux frontend and migrated the backend from Symfony PHP to Ruby on Rails, adding WebRTC playback.

I developed live viewer counts and chat state with WebSockets and Redis, plus a TypeScript real-time chat server and service APIs. I also implemented RTMP ingest with custom webhook authentication and operated OvenMediaEngine and nginx-rtmp.

At Servicios Integrales Leimar, C.A., I developed and maintained the internal Atlas ERP with Next.js, MySQL, RabbitMQ, and Apache Solr search. I also built CI/CD pipelines and worked on inventory management and reporting modules. My side projects include Kancha, a live sports streaming platform, and PlanAuto, a car maintenance and expense tracker.
