I build web and streaming applications with React, TypeScript and Node.js. Since Nov 2021, I've worked on TVI Player at Media Capital, across web and Smart TV platforms (LG webOS, Samsung Tizen and Android TV). Brazilian, based in Madrid.
Stack: React 路 Next.js 路 TypeScript 路 Node.js (Fastify, NestJS) 路 PostgreSQL 路 MongoDB 路 Docker
I have worked on TVI Player since Nov 2021. Media Capital reported approximately 1M monthly unique users in 2020 (before I joined), ~1M in 2024, and 2M+ in May 2025. These are published product figures, not individual results; reporting methodologies may differ. Sources: Media Capital, 2020 annual report, 2021 figures, 2024 report, MC News, ECO.
TVI Player 路 Media Capital, Nov 2021 to today 路 streaming platform and Smart TV apps
- Web: React, TypeScript and Vite on the front, Node.js and Fastify on the back, shipped through Jenkins CI/CD.
- Smart TV: I own the apps for LG webOS, Samsung Tizen and Android TV (React, TypeScript, Cordova): video players, HLS / DASH, VAST / SCTE-35 ads, remote navigation and focus management, debugged on real devices.
- Reach: a responsive experience for both legacy TV boxes and modern smart TVs.
