Web and desktop systems I've built. Each one has a case study with real screenshots of the system running.
Web platform to monitor air, water and soil quality at the Vereda del Lago park in Maracaibo: it shows each reading in real time, classifies it by its range and generates PDF reports.
System for computer labs: equipment inventory by department and a ticket help desk with assigned technicians, audit log and role-based permissions.
Portal for the María Calcaño Public Library of Zulia, built for the Regional Libraries Encounter: nine sections with documents you read right on the page, an editing mode to update it without coding, and a visitor counter.
Desktop application to keep a clinic's medical records: patients, consultations and doctors in one place, with role-based permissions and records you can export to PDF.
