I'm a Senior Frontend Engineer with 13+ years of experience building high-performance web and mobile applications across fintech, healthcare and enterprise retail. I specialize in React, TypeScript, Next.js and React Native, with a deep focus on design systems, micro-frontends and AI-assisted development workflows.
I care about interfaces that feel fast and clear, and I measure the impact: conversion lifts, faster releases, accessible products shipped end-to-end on the frontend.
Highlights
Revenue and growth, Gen Digital: shipped performance-optimized UI variants that boosted widget engagement by 105% and drove a $54k/week revenue lift.
Zero-wait deployments, MZ Group: led a micro-frontend migration with Module Federation that cut release approval cycles from 7+ days to zero.
Enterprise-scale mobile, Luizalabs (Magalu): built 5+ React Native apps used across 1,000+ retail stores, with offline-first sync.
