Case Studies & Labs

Where We Build
In Public

Real engineering. Real trade-offs. Real systems. These are the projects we've built, the problems we've solved, and the architectural decisions we've made — documented in full so others can learn from them.

Nendi

A Kafka-Free Database Streaming Daemon in Rust

Nendi is a standalone, high-performance Change Data Capture daemon built in Rust. It collapses the traditional Debezium → Kafka → Consumer pipeline into a single binary, targeting sustained throughput of 100,000+ writes per second on commodity NVMe hardware — without a JVM in sight.

Sando

An Event-Driven Media Processing Platform in Rust

Sando is a production-grade media server built in Rust. It handles the full lifecycle: chunked upload with SHA-256 deduplication, GPU-accelerated transcoding (NVENC / QSV), HLS/DASH adaptive streaming, and real-time signed URL delivery.

URLs

A URL shrink ray written in Rust

URLs turns bloated links into compact codes through a stateless codec or a memory-efficient stateful store. Its sealed minimal perfect hash index holds 4.3 million URLs in about 14.9 MB of RAM, with zero-copy reads from memory-mapped logs.

More Case Studies Coming

We're actively building Pori (secure tunneling), Colink (networking), and several client engagement systems. Each will be documented here as we ship.
