Frontend engineer on the OTT streaming platform of a major Brazilian pay-TV operator, built with React Native (via Renative) and deployed across Samsung Tizen and LG webOS. I build the Bitmovin video-player engineering layer for live, VOD, and catch-up playback — DRM, CDN connection management, audio/subtitle switching, and channel-change retry logic — and the end-to-end purchase flow (subscription + transactional VOD). Led the MiniEPG performance refactor: built a custom Performance API monitor to baseline channel-change load time, then cut it by ~30% via server-side EPG pagination. Also delivered content-detail screens, analytics instrumentation (GTM + Youbora), QR-code sign-in, and scoped the App Lite build for legacy TV hardware.

Coordinated two simultaneous OTT product streams — a multi-client white-label platform and a broadcaster's streaming app — across a ~16-person cross-functional org spanning Web, Android, iOS, and Smart TV. Delivered 18+ epics end to end — writing functional specifications, translating Figma designs into implementation stories, and coordinating stakeholders across five countries. Spearheaded a broadcaster's Smart TV launch on Samsung Tizen and LG webOS, coordinated Server-Side Ad Insertion (Amagi) and FAST channel delivery, drove the Multichannel EPG (vertical virtualization + D-pad spatial navigation), and led an analytics restructuring to GA4 + Youbora.

Frontend engineer on the OTT streaming platform of a major Brazilian broadcaster, built on Next.js. Rebuilt the web video player from scratch, replacing a Shaka Player foundation with a custom HTML5 solution on hls.js. Redesigned the main content carousel's architecture and rendering logic, cutting time-to-first-render of the visible tiles by ~15% (measured with User Timing marks around the mount-to-first-paint window). Built Chromecast integration end to end, restructured routing across live radio / VOD / podcast areas, delivered the Search page redesign, and contributed to accessibility work (ARIA, VoiceOver) across web, iOS, and Android.

Worked across the full stack on OTON, a web-based management platform for ISPs operating fiber networks. Built core modules: subscriber management with role-based access control, PON/OLT/ONT network-equipment monitoring, and a billing module covering invoice generation, payment tracking, and subscription-plan management. Automated reporting dashboards and built an internal support/ticketing system. Stack: React, Redux, Node.js, Sequelize, MySQL, SQL Server, Docker.
