Rust-Powered APIs with Axum – A Complete 2025 Guide

Ashish Sharda — Mon, 02 Jun 2025 12:30:51 +0000

If you’re building backend systems in 2025 and not using Rust + Axum, you’re missing out on a powerhouse combo.

I just published a complete guide walking through:
✅ REST API structure with Axum

✅ Type-safe extractors

✅ Async database queries with sqlx

✅ Observability (tracing + Prometheus)

✅ WebAssembly for client-side validation

✅ Graceful shutdowns, Docker, and more

Our AI/ML Model Hit 99.8% Accuracy—Then Failed in Production. Here's Why.

We built a fraud detection model that was “perfect” in testing—99.8% precision, extensive validation, bias audits, the works.

Then we deployed it.

Within 3 weeks, it was letting real fraud through and flagging legitimate users at 10x the expected rate.

In this postmortem, I break down:

Why test metrics lie in production
How feedback loops and real-time behavior broke our model
The hidden cost of AI maintenance
The ethical implications we missed
