About
Hi, I’m Ernesto Redonet Herrera, a cloud, payments, and real-time systems engineer based in Havana, Cuba, open to remote opportunities across the Americas and Europe. With 6+ years of experience building high-availability platforms using Node.js, PHP, AWS, PostgreSQL, and React, I design scalable microservice architectures and robust payment integrations (Stripe, PayPal) and real-time communication via MQTT and APIs.
One notable project involved designing and deploying a comprehensive web platform for a beauty salon, featuring an interactive appointment-management module with calendar and WhatsApp notifications that reduced no-shows by 30%, real-time profit-margin calculations for services, and a multi-currency POS integrating Stripe and PayPal to process USD and EUR with automated daily reports and faster end-of-day reconciliation.
