PCT
Whether it’s a fresh greenfield build or an evolving legacy system, we help you understand, build, improve, and future-proof your software. Building and running web platforms is our daily business — as is writing clean, maintainable code.
Long-term support & operations: After go-live, we remain your technical partner — reliable, pragmatic, and committed to long-term stability.
We own our technology. The technology we focus on is Ruby on Rails — a stable, mature framework that continues to power countless web applications and backend services for mobile apps. Its promise has always been “The One-Person Framework” — empowering small teams to move fast and deliver cost-efficient MVPs within days. With the right experience, Rails applications can scale to serve hundreds of thousands of users and millions of requests per day.
Running a Rails application can be a rewarding and exciting endeavor — especially when it’s done right.
Good people, good software*: We maintain strong connections within the Rails community — in the Rhine-Main area and beyond. Whether you’re looking for technical input, project support, or just a good conversation among developers, good networking is where great projects begin.

It's your turn now! Have an idea, a project, or maybe the next big thing in mind? Let’s make it real. Reach out to us today — great products start with a simple conversation.Service
We work with agile methods and a transparent, collaborative process. Requirements are captured in tickets and refined together with the client.
Each feature is implemented with automated tests, ensuring reliability and future extensibility. Short development cycles and frequent deploys — sometimes multiple times a day — are part of our workflow. Every live system is monitored with exception tracking and performance metrics. The result: software that’s maintainable, documented, and always in a production-ready state.
