What I'm looking for

Ich suche eine technisch herausfordernde Rolle im Fullstack/Lead-Umfeld, in der ich Echtzeit‑Systeme und skalierbare Architekturen weiterentwickeln kann.

Ich bin Fullstack-Entwickler mit über 21 Jahren Erfahrung in Softwareentwicklung und umfangreicher Praxis in PHP- und JavaScript-Stacks.

Als Lead Developer habe ich sicherheitskritische Systeme zur Echtzeit-Ausgabe und Analyse von Standort- und Sensordaten entwickelt, inklusive Integration externer Tracking-Anbieter und performanter Datenpipelines mit Redis und MongoDB.

Ich habe zahlreiche Fullstack-Projekte umgesetzt — von Game-On-Demand- und POS-Anbindungen über mehrsprachige Website-Cluster bis hin zu CRM-SaaS-Plattformen — und arbeite gern in agilen Scrum-Teams unter Einsatz von Testautomatisierung (Cypress, Jest, PHPUnit).

Technologisch setze ich schwerpunktmäßig auf Laravel, Angular, TypeScript, NodeJS und moderne Infrastruktur-Tools wie Docker, AWS und Redis; ich bringe zudem Erfahrung als Gründer und in eCommerce-/Marketing-Beratung mit.
