Rust Development

Performance-Critical Systems — No GC Pauses, No Memory Leaks

Rust Development illustration

Your backend isn’t the bottleneck today. It will be. We engineer memory-safe Rust backends built for the load you’ll have in 18 months — not the traffic you have now. New builds and migrations from Python, Node.js, or Go alike.

Obox Systems is an international software engineering company headquartered in the US, specializing in high-performance Rust systems and backend infrastructure. Engagements are led by our CTO, backed by a structured team with mandatory peer review; NDA available on request.

Why Rust — the evidence: Firecracker (Rust, AWS, in production since 2018) has fewer than 10 CVEs and zero VM escapes; QEMU (C, since 2003) has 300+ CVEs, with 10–50 new each year. Same hardware boundary, same isolation job — only the language changed.

We can help you with:

  • Production Rust backends and APIs — REST, GraphQL, WebSocket, and gRPC services on Axum, Actix-web, and Tokio
  • Predictable latency at peak load — no garbage-collection pauses, no p99 spikes, more throughput from every core
  • Fewer production incidents — Rust’s ownership model removes memory and data-race bugs before release
  • Migrations without disruption — critical services moved from Python, Node.js, or Go behind the same API
  • Production readiness from day one — tests, CI/​CD, containerized deployment, and observability
  • Full ownership — source code, architecture docs, and runbooks stay yours

We focus on backends where throughput, latency, or reliability is business-critical.

The Diagnostic Architecture Audit delivers an architecture and risk review with a technical roadmap in five days — a written plan you own.

FAQ

  • We’ve shipped Rust systems handling millions of daily requests for FinTech and trading platforms. Most Rust freelancers are learning the borrow checker on your project. We’re certified Rust engineers delivering production-grade performance from day one.

  • Firecracker (Rust, AWS) has fewer than 10 CVEs and zero VM escapes; QEMU (C) has 300+ — same hardware boundary, different language. Rust rejects buffer overflows and use-after-free at compile time, giving you C-level performance with memory safety built in.

  • Most clients come to us after someone else built it in Node and ran into latency and memory spikes. We typically solve this by rewriting the core logic in Rust and reduce resource load by 40–70%.

  • Because we don’t fix things twice. You’re paying for performance, not cleanup.

  • Contact us to discuss your project. Share your project idea, any assets (designs, specs, links), and your main goals — we handle the technical part from there.

  • Rust is our core, but we don’t force it where it doesn’t fit. We integrate with C++, TypeScript/​JavaScript, and Python — choosing the right tool for each component. Data science layers stay in Python, front-ends in TypeScript, performance-critical backends and systems code in Rust.

  • Built a Rust payment routing engine 20–30% faster than Go with 10–20% fewer parsing errors. Also delivered a crypto platform handling 100,000+ WebSocket subscriptions, and for a major IoT manufacturer eliminated 100% of crash-causing races while cutting codebase size 45%.

  • Yes. We sign NDAs before any technical discussion begins, on request.

  • You do. IP, source code, architecture docs, and deployment runbooks are fully assigned to you on completion — no vendor lock-in.

  • Yes. Signed contracts with fixed scope per phase. US company (Wyoming LLC) — you’re contracting with a registered entity, not an individual.
