Commits to the loyalty widget

Markets localized (AR / EN / ES / PT)

Charting

Designed and built the dashboard’s shared Recharts-based charting library (bar, pie, needle-gauge, and dual-axis line components) and the original 8-chart analytics module — later reused platform-wide for campaign and audience reporting.

Automation

Built CoreAds, a visual node-based workflow builder for AI-driven marketing automation, supporting branching decision logic, audience/segment targeting, and WhatsApp messaging triggers — the platform’s flagship campaign-orchestration feature.

Platform

Maintained and extended an embeddable loyalty widget across a 3+ year VTEX eCommerce integration, shipping authorization-flow fixes, cart/cashback logic, and a React-runtime-isolation (IIFE) fix for host-page conflicts.

Migration

Migrated the dashboard’s legacy component library to Material-UI v7 and a modular React architecture, cutting code duplication 20% and design-to-development handoff time 30%.
