Projects

Event-driven document management system (Next.js + NestJS + BullMQ) for the School of Software Engineering. Cut report generation time from ~30s to ~9s (70% faster) and absorbed >200 documents/month with zero queue backlog by moving heavy Google Docs API work into BullMQ workers.

Full-stack restaurant management platform (Next.js + NestJS + WebSockets) that cut order-error rates by ~30% and reduced kitchen-to-cashier ticket turnaround from minutes to seconds via real-time order sync across waitstaff, kitchen, and cashier roles.

Astro-powered redesign of the Technical University of Ambato (UTA) home page. Cut Largest Contentful Paint to under 1.2s and Lighthouse Performance to 95+ on mobile, replacing a slow legacy WordPress front page that students used as the main entry into academic services.

Spring Boot + PostgreSQL POS for small Ecuadorian retailers. Replaced spreadsheet inventory + manual tax reports with a single transactional system that emits SRI-validated XML invoices on every sale — eliminating end-of-month tax-filing scrambles and removing the most common source of inventory drift.

Production e-commerce platform (Next.js 14 + Prisma/Postgres) with a custom admin dashboard. Sub-1.5s LCP on product pages, real-time inventory sync that eliminated double-bookings during peak drops, and a checkout flow tuned to reduce cart abandonment.

AI-powered payment simulator (Next.js + Spring Boot + AWS Rekognition) that authenticates transactions via facial verification in <2s end-to-end, removing the need for password or card entry at the point of sale. Built to demonstrate how biometric auth shrinks checkout friction and card-fraud surface area.
