LOW-LATENCY SYSTEMS

Custom network layers and Rust engines where every millisecond counts

LOW-LATENCY SYSTEMS Logo

Bare-metal performance meets production-grade reliability — built in Rust, measured in microseconds

Standard cloud tools and off-the-shelf proxies become the bottleneck once you’re processing millions of requests per second — GC pauses violate SLAs, horizontal scaling inflates cloud bills, and generic gateways can’t handle your custom protocols. We engineer high-performance network infrastructure using Rust and eBPF: custom proxies, load balancers, and real-time protocol engines for sub-10ms latency and 100K+ concurrent connections.

Client-verified: a crypto trading platform sustained 100,000+ simultaneous WebSocket subscriptions — production-stable from day one (Clutch, New York); an ad platform RTB engine achieved sub-150ms response times with 80% spam/bot reduction. We identify your exact bottlenecks and fix them — often a targeted microservice in Rust for the critical path, integrated with your existing stack via gRPC, REST, or shared memory.

We can help you with:

  • Custom proxy & load balancer development
  • High-concurrency network architecture
  • System performance profiling and optimization
  • Custom protocol parsing and implementation
  • eBPF-based observability and acceleration
  • Low-latency backend systems
  • Real-time stream processing (TCP/UDP/WebSockets)
  • Migrating legacy system bottlenecks to Rust
  • Advanced memory management & thread optimization
  • Tech lead support and consulting calls

FAQ

  • We focus specifically on the critical path. Instead of just writing business logic, we deal with memory allocation, kernel-level networking (eBPF), lock-free concurrency, and custom protocols using Rust to achieve sub-10ms latency and massive throughput.

  • Rust offers the speed of C and C++ without the memory safety vulnerabilities (like segfaults or buffer overflows). It allows us to build extremely fast, highly concurrent systems with zero garbage collection pauses, which is crucial for low-latency network engineering.

  • Not usually. We are pragmatic. Often, we identify specific bottlenecks (like an API gateway or a data relay) and build a highly optimized custom proxy or microservice in Rust just for that critical path, integrated directly with your existing stack via gRPC, REST, or shared memory.

  • We heavily integrate benchmarking and profiling from day one. Every milestone includes rigorous load testing and stress testing to ensure the system meets your specific latency (p95, p99) and requests-per-second (RPS) requirements.

  • Our autonomous systems engineers ensure smooth development, while a manager monitors progress. Each milestone includes strict CI/CD checks, memory leak profiling, and code reviews. Our CTO oversees all system architectures to ensure top-tier performance.

  • A crypto trading platform sustained 100,000+ simultaneous WebSocket subscriptions with dynamic connection management — production-stable from day one (Clutch-reviewed, New York). On a separate project, we engineered an ad platform RTB engine achieving sub-150ms response times with 80% spam/bot reduction — processing high-volume real-time bidding without off-the-shelf tools.

  • Low-latency systems have a known risk: performance requirements often surface edge cases only visible under real production load. We build load testing into every milestone, profile on representative hardware, and fix performance issues before they reach your users — not after.
