Frontend Architecture: Built with Next.js to deliver a high-performance, server-side rendered (SSR) user interface, ensuring fast load times and SEO optimization for the German market. Core Backend: Utilized Express.js (Node.js) to handle robust user management, authentication, and subscription logic, serving as the central orchestration layer. AI Microservices: Developed a dedicated AI processing layer using FastAPI (Python) to handle high-concurrency requests and interface with machine learning models efficiently. Generative AI Engine: Implemented a model-agnostic architecture capable of leveraging multiple Large Language Models (LLMs), including Anthropic Claude, OpenAI GPT, and Google Gemini. This ensures the platform selects the best model for specific content generation tasks. Presentation Generation: Engineered a custom PowerPoint XML manipulation algorithm to programmatically construct native .pptx files, ensuring pixel-perfect layouts and editability rather than simple image-based slides. Infrastructure & Scalability: Cloud Provider: Deployed entirely on AWS for high availability and security. Orchestration: Containerized services managed via Kubernetes, allowing the system to auto-scale based on user traffic and generation load. DevOps: Established comprehensive CI/CD pipelines to automate testing and deployment, ensuring seamless updates and feature rollouts.
