Back to original languageAbout Sebastian
Do you have a manual process, a software idea, or a workflow where you think: there must be an easier way? That's exactly where I come in.
I develop custom web applications, internal tools, automations, and AI-powered solutions for companies and projects where standard software doesn't fit the specific problem.
My focus is on TypeScript, Next.js, React.js, and Node.js, as well as the integration of modern AI models and APIs.
From the initial idea to the functional application, I handle concept development and technical implementation. This includes MVPs, SaaS products, dashboards, internal tools, process automations, API integrations, and custom AI functionalities.
With SignalOne, for example, I conceived and developed a complete SaaS platform for performance marketing – including a dashboard, campaign and creative management, testing logic, data processing, and AI-powered analysis.
My approach: First, understand the specific problem. Then, define the technically sensible solution. Finally, develop functioning software – without unnecessary complexity and without technology for technology's sake.
If you want to simplify a process, implement an idea as an MVP, or meaningfully integrate AI into an existing application, I can support you with the concrete implementation.
