Top SchoolKasper Stöckel is a seasoned full‑stack Ruby on Rails and React freelancer with 16 years of hands‑on experience building scalable web, mobile and desktop applications. Based in Berlin, he routinely owns projects end‑to‑end—from UX implementation and heavy backend coding to deployment, self‑hosting and GDPR‑compliant ops (encrypted disks, backups, Nginx/Apache/Docker).

Comfortable across languages and datastores (JavaScript, SQL variants, Mongo, PHP, Java), he combines deep Rails expertise with practical DevOps skills to deliver production‑ready systems. He maintains a public GitHub and prefers direct client engagement rather than working through recruiters.
