Building a 22-service e-commerce platform in Rust (Runs on ~300MB RAM)

I'm 17. For the past 6 months, I've been diving deep into Rust to answer a question for myself: "Is Rust actually viable for complex, enterprise-grade backend architectures, or is it just hype?"

To test this, I built a full distributed e-commerce system (22 microservices, gRPC, Event-Driven) using Axum and Tokio. This is not meant as “how everyone should build”, but as an exploration of trade-offs.

Some hard lessons I learned along the way: Complexity vs. Performance: … The "Memory Shock": … (idle baseline; load benchmarks still in progress) Over-engineering: …

I'm currently squashing the final bugs…

I'd love to hear from senior folks here: …
