I’ve been exploring WebAssembly with Rust lately, and I thought I’d share my recent learning with you. Instead of the usual React + Web API combo we’re all used to, I decided to see what it takes to build an entire web app in Rust today. Spoiler alert: it’s surprisingly straightforward! If you’re interested in more findings like this, let me know and I can share more in my next blog post. For now, let’s dive into building a practical password stre...")

Simple inserts capped out, and every new index or trigger hurt worse. When we swapped our approach to bulk ingest with Postgres COPY and let Rust’s async runtime do the heavy lifting, something changed. We watched qps spike past 120k, and the usual bottlenecks faded — until the next one found us. Simple in...")
