My full SaaS Architecture Explained: Next.js, Bun, Docker, PostgreSQL, FFmpeg & Redis

In this video, I break down the entire architecture behind my SaaS project — from the frontend to the backend, database, job queues, and media processing.

Here’s the tech stack I’m using and why:
Next.js + TypeScript → Frontend + API routes, typed safety, fast developer experience.

Bun → Lightning-fast JavaScript runtime and package manager, better than Node for performance and simplicity.

Docker → Containerized services, making the SaaS portable and production-ready.

PostgreSQL + Prisma → Rock-solid relational database with modern ORM for schema safety and migrations.

Redis + BullMQ → Distributed job queues for background tasks (video/audio processing, emails, scheduling).

FFmpeg → Heavy-duty media processing for encoding, transcoding, and handling user-generated content.

This is the backbone of my SaaS scalable, modern, and optimized for both performance and developer velocity.

If you’re curious about building production-grade SaaS apps, or just want to learn how all these pieces fit together, this walkthrough will give you the big picture.
