Next.js 14 Architecture & Performance Migration: Led platform migration of the primary customer portal from Next.js 9 Pages Router to Next.js 14 App Router in an NX monorepo using React Server Components and streaming—reducing initial JS bundle size by 50%, cutting TTFB by 40–60%, and improving Core Web Vitals (LCP: 2.5s → 1.2s, CLS: 0.20 → 0.06). Unified Regional Experience: Architected a unified customer dashboard consolidating 5+ core workflows (orders, cases, lists, recommendations) across 3 regional brands (Falabella, Sodimac, Tottus) into a single page, boosting user engagement by 25%. High-Scale Backend Resiliency: Engineered resilient connection management for high-concurrency Node.js services during peak Cyber Sale events—handling 10x traffic spikes via LIFO connection pooling, adaptive retry logic, and real-time Prometheus telemetry. Cut socket-reset recovery to ¡50ms, reducing P99 latency by 40% and sustaining 99.95% availability during upstream degradations. Tenant-Aware BFF Micro-Frontends: Designed a tenant-aware micro-frontend Gift Cards module using NestJS BFF architecture for session-based cookie integration and normalized domain payloads, reducing client payload sizes and simplifying regional deployments. Engineering Excellence & AI Workflows: Guided a team of 5+ peers through technical code reviews to enforce Next.js/React best practices, testing standards, and safe deployment patterns. Integrated AI tools (GitHub Copilot/Cursor) across development workflows to accelerate unit test generation with Jest, increasing code coverage and feature velocity.
