What I'm looking for

I'm looking for full-time remote engineering engagements where I can build secure, high-performance web platforms, lead complex migrations, improve delivery practices, and collaborate across product, design, and non-technical teams.

At futalis GmbH, I lead the Next.js 16/React 19 frontend rewrite and build the NestJS/TypeScript headless commerce API replacing Magento. I’ve delivered 57 routes, 500+ reusable components, secure multi-realm authorization with PostgreSQL Row-Level Security, recurring subscriptions, and six PAYONE payment methods.

I’ve worked remotely across German, Qatari, and French teams since 2020, modernising ERP and SaaS platforms while keeping live systems available. My work spans API architecture, performance, security, zero-downtime migration, and automated delivery—improving Lighthouse performance from 74 to 91, reducing client bundles by 35%, and cutting deployment and content turnaround times.
