    Concept, architecture, and end-to-end implementation of a comprehensive SaaS platform (for automating dunning processes). The system is aimed at B2B customers and integrates seamlessly with existing accounting systems (such as Lexoffice and sevDesk). In addition to the actual web application (ReactJS), the project includes a marketing website, its own license server, a powerful backend (Node.js/Supabase) for processing background jobs, and connection to the Stripe payment provider.

    • API Integration: Developing interfaces and connecting external REST APIs (Lexware, sevDesk, Stripe SDK) including fallback mechanisms and API mocking.
    • DevOps & Hosting: Deploying infrastructure via Docker Swarm, setting up CI/CD pipelines, and ensuring data security/GDPR compliance.
    • AI-Assisted Development: Utilizing AI development tools (e.g., AI coding agents, advanced prompt engineering) for code generation, refactoring, security audits, and API documentation.
    Technologies & Skills Used:
    • Frontend: ReactJS, TypeScript, TailwindCSS, Vite
    • Backend & Databases: Node.js, Express, Supabase, PostgreSQL (incl. Deno Edge Functions)
    • Infrastructure & DevOps: Docker Swarm, Nginx, CI/CD (GitHub Actions), Secrets Management
