What I'm looking for

I'm looking to bridge technical infrastructure and business growth through strategic digital solutions, scalable systems, data synchronization, and AI automation that improves lead generation and operational speed.

I've spent more than eight years building high-performance websites and HubSpot solutions that connect technology with business goals. At Dinterweb, I turned Figma and PSD designs into responsive HubSpot CMS templates and custom WordPress themes.

I designed Node.js and Express middleware for bidirectional HubSpot API integrations, while configuring workflows, custom objects, HubDB, forms, landing pages, and membership sites. I also implemented technical SEO and performance improvements for speed, accessibility, and platform efficiency.

At Instituto de Diseño y Tecnología IDT Paraguay, I built LMS and virtual campus platforms with React, NestJS, and MySQL, and previously developed enrollment, grading, inventory, and cash-control modules using PHP and MySQL.
