🚀 A small discovery while testing our media management system

When building backend applications, we often focus on API performance, database queries, and business logic.

But there's another factor that can quietly increase infrastructure costs: the size of the files users upload.

Imagine users uploading 4 MB images for every post. As the application grows, so does the storage footprint, bandwidth usage, and image delivery cost.

Here are a few things worth considering:

🔹 Image Optimization: Resize and compress images before storing them.

🔹 Direct S3 Uploads: Use presigned URLs to let clients upload files directly to Amazon S3 instead of routing every byte through the backend.

🔹 Multiple Image Variants: Generate thumbnails and optimized versions for different screen sizes.

🔹 Caching & CDN: Serve frequently accessed media efficiently using a CDN.

🔹 Measure Before Optimizing: Monitor actual file sizes, traffic patterns, and storage costs before choosing a solution.

The interesting part of backend engineering isn't just making an API work. It's making the entire system efficient, scalable, and cost-effective as the number of users grows.

Sometimes, the biggest improvements come from optimizing the things we rarely think about.
