At Prompt Soluciones Integradas, I cut invoice analysis dashboard load time from 3–5 minutes to under 5 seconds by introducing server-side pagination and rewriting MySQL queries. I also built a PHP REST API connecting the EFFETools ERP with Microsoft Dynamics 365 CRM.
I fixed billing logic for USD/MXN invoicing under CFDI 4.0 and shipped an Advance Payment feature that generates matching income and expense e-invoices. I also rebuilt dashboards with real-time exchange rates using React Server Components.
For Microsoft 365 clients, I design document workflows that generate agreements from Excel data, convert them to PDFs, and route them for e-signature. At Dydetec, I built a digital medical records system for a specialty hospital using Next.js, React, Tailwind, and DataTables.
