Engineering for the entire stack
From high-performance websites to software, SaaS, tracking and operations. One partner for the technical foundation of your success online, from idea to live operation.
Web Engineering
High-performance websites that load fast, rank cleanly and turn visitors into customers. Engineering, not a builder, built for measurable results.
Learn MoreWeb App Engineering
Secure, scalable web applications: customer portals, dashboards and web apps built with modern web technologies. From the first release to a product that grows with you.
Learn MoreE-Commerce Engineering
Fast, clean online shops and headless commerce: from the product catalogue and checkout to ERP and payment integration. Built to sell, not just to administer.
Learn MoreSoftware Engineering
Custom software development that carries your processes: robust backends, APIs and integrations, built for low long-term cost and stable growth.
Learn MoreSaaS Engineering
SaaS development from MVP to a scalable product: multi-tenant, billing and user management, quick to launch and ready to grow without a rebuild.
Learn MoreInfrastructure
Infrastructure & DevOps for software that runs around the clock: cloud, containers, automated deployments and monitoring from one team. So operations become predictable instead of a permanent building site.
Learn MoreMeasurement Infrastructure
Server-side tracking with a dedicated GTM integration on EU servers in Germany: complete data despite ad blockers and consent, as a reliable basis for better marketing decisions.
Learn MorePerformance & SEO
Technical SEO from Germany: fast loading times, green Core Web Vitals and clean rendering as the foundation to rank measurably better and win more enquiries.
Learn MoreTechnical foundation
Clean, performant code is the bedrock. Everything else builds on it: ranking, conversion, scale.
Data over gut feeling
We measure instead of guessing. Decisions are based on solid numbers, not assumptions.
From our own experience
Rheinwork grew out of real problems we solved ourselves. We know your levers.
Got Questions? We've Got Answers!
From high-performance websites (built with Hugo where it fits) to web apps, portals and custom software, all the way to SaaS products, tracking infrastructure and hosting. If it needs to be technically sound, we build it.
Small and mid-sized companies, startups, founders and service providers, wherever a technically clean solution is needed instead of a pretty builder with no substance.
You reach out and receive a short questionnaire; based on it we put together a quote with a concise concept. Once approved, we start building. We deliberately favour a clear written assessment over endless calls. A phone call is of course still possible.
The right tool for the job: in practice mostly TypeScript, Go, React/Next.js, Hugo, Node.js and Postgres, plus AWS/Vercel, Docker and Google Tag Manager.
Yes, on request, including operations, monitoring and hosting on EU servers in Germany.
Every project is individual, so pricing is on request. Via the questionnaire we estimate effort and direction quickly and transparently.
