Meet Ralf

Founder of Stackcraft. Freelance web & software developer and backend engineer — with roots in QA from his first job in tech.

Our story

I'm Ralf, the founder of Stackcraft. I work as a freelance web and software developer — building websites, full-stack apps, and custom tools for startups and growing teams — while also working as a backend developer.

I also worked as a Junior QA Engineer — that was my first job in tech. It taught me how to think about quality early, test what matters, and ship with fewer surprises. That foundation still shapes how I build today.

Whether you need a marketing site, an internal tool, or a production software product, you work directly with me — clear communication, honest scope, and code that's ready to grow.

Freelance Web / Software Developer

I design and build web apps, software tools, and full-stack products for clients — from first prototype to production under the Stackcraft brand.

Backend Developer

By day I ship APIs, services, and data systems in a backend role — the same reliability mindset I bring to every client project.

Junior QA Engineer

My first role in tech — I worked as a Junior QA Engineer, learning how to catch bugs early, write solid coverage, and ship releases with confidence.
