Senior Full-Stack Developer with 10+ years building and running production systems end to end in PHP/Phalcon and Node.js/TypeScript (NestJS, Next.js). Built a 24/7 platform managing 250,000+ devices at ~5,000 events/minute and led the PHP → NestJS rewrite of a platform now serving 5,000+ active users. Hands-on from architecture to deployment and production support; mentor and coordinate a team of three developers.
Deep PHP/Phalcon foundation, complemented by modern Node.js/TypeScript with NestJS, Next.js and React.
Led the full rewrite of a PHP/Phalcon file-storage and identity platform to NestJS + Next.js (5,000+ active users). Re-architected background processing from process-per-request to RabbitMQ + 20+ workers, and cut device-query response times from 30+ seconds to ~5 seconds. Mentored and coordinated three developers while remaining hands-on.
Designed and built a Wi-Fi controller from the ground up and an internal operations platform (COVID-19 declarations, QR codes, scheduling, tasks, Face ID attendance); later upgraded core services from PHP 7 to PHP 8.
PostgreSQL ltree folder hierarchies, trash, public links and owner/editor/viewer permissions backed by SpiceDB. A Keycloak administration backend with bulk Excel user import/update, review workflows and audit logging. Separate HTTP, worker and cron workloads, Kafka for cross-application events and an iframe-based File Picker SDK.
Bulk configuration, diagnostics, network maps, device templates/tags and condition-based alerts via Telegram and email, letting ~5 operators manage 250,000+ devices. Message identifiers prevent duplicate processing and database transactions keep multi-step updates consistent. Integration APIs let other departments and systems consume device data for operational reporting.
An IAM service with bidirectional Keycloak synchronization and a Directory API for other applications. A paperless meeting system covering schedules, documents, attendees, live voting and controlled impersonation. Automated testing across three backend systems using Vitest and Playwright.
A platform for face-recognition devices, door locks, snapshots and attendance reporting. A multi-tenant version adds event triggers, alert conditions, recognition schedules and worker-based bulk processing.
