Backend Architecture for Text-to-Speech SaaS Platform

Process: Architected the server-side logic for a text-to-speech SaaS. The system manages API communication with top-tier AI voice models and handles large audio file storage securely.

AI Wrappers: Developed a custom backend wrapper for ElevenLabs/OpenAI APIs that tracks token usage per user and manages API cost limits. Storage Solutions: Integrated AWS S3 for secure, scalable storage of generated audio files, implementing signed URLs for temporary, secure user access. Latency Reduction: Implemented Edge Caching via Cloudflare to ensure audio files stream instantly to users in different geographical regions. Stream Processing: Handled audio streams on the backend to allow users to "listen while generating" rather than waiting for the full file to process.
