Herramienta Interna — CRM a medida en PHP y MySQL

Custom PHP 8 and MySQL 8 CRM for managing, auditing and analyzing large-volume contact databases. What it is: a proprietary, custom-built CRM platform —not a template— bringing queries, reports, bulk import, normalization, backups and users into one panel. Who it is for: organizations with a very large contact database that need to manage, clean and exploit that data reliably, without spreadsheets. What it includes: - Visual SQL-like query builder with combinable filters and presets. - Interactive reports with Chart.js: demographic, geographic, time-based and UTM. - Bulk CSV import with preview, flexible mapping and duplicate detection. - Automatic normalization of emails, phone numbers (+57) and Colombian geography. - Users and roles with granular permissions, auditing and incremental backups. Built with: PHP, MySQL, PDO, Tailwind CSS, Chart.js, Apache and Argon2id. What it offers an agency: the ability to build a mission-critical internal data platform —Argon2id, CSRF, rate limiting and auditing, queues and normalization— without a closed product.
