Marcos Ojeda Silva

I've built and maintained critical software for Integra Chile, Sistemas Expertos, and Patagonia Media across production and hospital operations.

At Integra Chile, I maintain the plant management system and reduced a critical report from over five minutes to two seconds through SQL optimization and code refactoring. I also led a three-developer team and built an Astro and React application for production cost calculation.

Previously, I evolved hospital ERP systems, patient-management modules, electronic prescriptions, and high-cost medication workflows. I developed scheduled chronic-prescription deliveries for Hospital de Puerto Montt to improve care for patients with long-term treatments.

I enjoy modernizing legacy systems, automating integrations between cloud APIs and local databases, and applying solid development practices across the full software lifecycle.
