I work across React, Next.js, React Native and Node.js - focusing on performance, architecture and shipping products that hold up in the real world.
A snapshot of the kind of problems I work on - high concurrency, large user bases and reliability under pressure.
Concurrent users simulated under load test
WhatsApp groups automated for promotions
A mix of frontend architecture, mobile engineering and backend reliability - chosen to show range, not volume.
Each case is framed by the engineering constraint, the system boundary, and the outcome it moved.

Public streaming platform focused on scalable delivery, playback reliability, and frontend performance under peak traffic.
SSR overloaded the limited frontend infrastructure at around 10,000 concurrent users.
Scaled from around 10,000 to over 3 million concurrent users in load testing.

Led mobile development for a driving behavior app using React Native, Expo and native SDK integration.
The app needed native telemetry without making product screens depend on platform-specific details.
Production-ready mobile application with native integrations and precise telemetry.
Grouped by where I tend to add the most leverage. Not a checklist - these are the areas I keep going deep on.
Component systems, data layers and rendering strategies that scale beyond the demo.
Cross-platform apps with native bridges where it matters: telemetry, sensors, deep OS integration.
Concurrency, idempotency and consistency patterns for systems that can’t silently corrupt data.
Caching, edge delivery and client-side data strategies that take pressure off origin servers.
Pragmatic scoping, user-facing tradeoffs and shipping the version that actually moves metrics.
Design and delivery of practical AI features using LLMs, retrieval pipelines, evaluation loops, and production-safe integration patterns.
Senior frontend and fullstack roles delivering production software for high-traffic platforms and venture-backed startups.
Public streaming platform (Tela Brasil) serving large-scale video content nationwide.
I lead the react native development of the SafePilot® app, a platform for analyzing driver behavior, focused on safety, efficiency, and responsibility in traffic.
Delivered web and mobile products end-to-end across affiliate and SaaS domains.
Short, opinionated pieces on architecture decisions, concurrency, and what I have learned shipping software.

I am a software engineer from Brazil with strong frontend expertise and fullstack experience. I have worked on high-traffic web platforms, React Native apps with native SDK integrations, and systems where concurrency, idempotency and reliability matter. I care about pragmatic architecture, performance and building products that survive real-world usage.
Open to senior frontend, fullstack and mobile roles - full-time remote or contract. Comfortable working across LATAM, US and EU timezones.
