LOW-LATENCY SYSTEMS

FAQ #

• What sets your low-latency service apart from standard backend development?

  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.
• Why do you heavily use Rust for these projects?

  Firecracker vs QEMU makes Rust’s impact measurable: Firecracker (Rust, AWS, since 2018) has fewer than 10 CVEs and zero VM escapes; QEMU (C, since 2003) has 300+ CVEs. Rust removes buffer overflows and use-after-free at compile time, with no GC pauses or memory surprises.
• Do I need to rewrite my entire system?

  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.
• How do you ensure the system actually performs under load?

  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.
• How do you ensure quality deliverables without me micromanaging?

  Benchmarking and profiling are built into every milestone, not added at the end. Each gate includes CI/CD checks, memory leak profiling, and load tests against p95/p99 latency and RPS targets. CTO architecture reviews help produce systems like 100,000+ stable live WebSocket connections.
• How has your process transformed a complex project?

  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.
• Do you sign NDAs?

  Yes. We sign NDAs before any technical discussion begins, on request.
• Who owns the code after delivery?

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

  Yes. Signed contracts with fixed scope per phase. You’re contracting with a registered entity, not an individual.
