We develop secure and scalable server architectures, APIs and databases that form the backbone of your digital products. [Schedule Consultation](https://www.codayweb.de/en/contact) ### Your Benefits - High-performance APIs - Secure data processing - Real-time functionalities - Seamless integrations Trusted by leading companies - MS Schlüsseldienst Wetzlar - Lindener Ratsstuben - Sanitär Batherm - MS Schlüsseldienst Wetzlar - Lindener Ratsstuben - Sanitär Batherm ![Image](https://www.codayweb.de/images/app-dev/mockup-app-kalenderansicht-datum-auswaehlen-smartphone-oktober.webp) Our Process ## Measurable success in 5 steps. 01 ### Discovery & Architecture We analyze your requirements, choose the optimal tech stack (Next.js, Node.js, Supabase) and design a scalable system architecture. 02 ### UX/UI Design Phase Before we write a single line of code, we visualize the user experience. Wireframes, prototypes and high-fidelity designs ensure clarity. 03 ### Agile Development We develop in short sprints with regular updates. You see progress live and can give feedback early. 04 ### Quality Assurance Automated tests, code reviews and performance audits ensure your application runs error-free and blazing fast. 05 ### Deployment & Scaling We bring your application live (Vercel/AWS) and provide necessary monitoring to keep it stable even with high user numbers. Your Benefits ## We think in ROAS, not in clicks. Our clients don't choose colorful slides, they choose a team that understands marketing as an investment. We think in results, plan with clear goals, and deliver transparently. [Get in Touch](https://www.codayweb.de/en/contact) ### High Performance Load times under 1 second and perfect Lighthouse Score are our standard, not the goal. ### Scalability First We build architectures that grow with your success. From 100 to 100,000 users without redevelopment. ### Modern Tech Stack We rely on Next.js, React, TypeScript and Tailwind – the gold standard of modern web development. ### Security by Design Security is not a feature, but a foundation. GDPR-compliant, encrypted and safe from threats. ### Transparent Code No vendor lock-in. You receive clean, well-documented code that belongs to you. ### Experienced Team Your project is implemented by senior developers who love complex challenges. ## Frequently Asked Questions (FAQ) We work transparently. Here are answers to the most important questions. We primarily use Next.js, React, TypeScript and Tailwind CSS. For databases we use Supabase (PostgreSQL) and for CMS solutions headless systems like Sanity or Strapi. That depends heavily on the scope. A corporate website takes approx. 4-8 weeks, more complex web apps or e-commerce solutions 3-6 months. We set up hosting infrastructures (mostly Vercel or AWS) that run in your name. We take care of setup, maintenance and scaling. Our projects typically start from €10,000. For complex web apps or shops we are usually between €25,000 and €50,000. ## Let's start your project. No standard solutions. We develop exactly what you need for your success.
