Is your system ready for a success that will break it?
We design and build high-load systems for peak traffic: architecture, code, load proof, delivery. First step — Discovery in 1–2 weeks with a plan and estimate.
25M+ messages/day · 15,000+ connections · 15k RPS without 503 — production numbers, not slides.

Architecture, Not Code
We start by designing a fault-tolerant architecture. Thinking about 10x, 100x load.
Load Testing as Religion
We simulate scenarios exceeding the wildest forecasts by 2-3 times.
Auto-scaling
Pay only for the resources you really need right now.
Complex Technologies — 24/7 Stability
Microservices
If one element fails, it won't crash the entire site. Updates are faster and safer.
Caching & Load Balancing
Lightning-fast response speeds even with thousands of concurrent users.
Monitoring & Alerting
We see anomalies before they become problems. We eliminate them before failure.
15,000 peak connections — no 503

Event peak audience — the system held the load.

Proxy CPU
At peak, frontend and backend still had headroom.
pre-campaign
stress test
Bottlenecks fixed before traffic, not after an incident.
Outcome: a predictable peak, measurable headroom, and runbooks for the team. Typical entry for similar work — Discovery in 1–2 weeks with a quote to reinforce or Build.
Cases: Proven by Scale
FAQ for CTOs and Business Owners
We fix specific metrics in the SLA: API response time (e.g., <200ms for 99th percentile), uptime (99.9%+), and max RPS. Failure to meet metrics incurs financial liability.
No. We use the Strangler Fig pattern: gradually extracting critical parts into microservices without stopping business operations. Full rewrites are a risk we avoid.
We set up async DB replication, regular PITR backups sent to S3 storage. We also conduct drills (Chaos Engineering) to ensure recovery works.
Our architectures are designed for horizontal scaling. As traffic grows, we automatically add instances (Kubernetes Autoscaling) and shard databases. The limit is only your infrastructure budget.
Impossible. All infrastructure is described as code (IaC — Terraform/Ansible). We hand over repositories, deployment documentation, and Runbooks for your in-house engineers.
You pay not for code, but for insurance against downtime. One hour of unavailability for a large e-commerce site can cost millions. We build a system that saves this money by preventing accidents.
