What we design and build

Microservice platforms. Independent services with clear boundaries and contracts. Each can be scaled and deployed separately.

Event-driven systems. Kafka and NATS for event streams: orders, transactions, telemetry, logs. Guaranteed delivery and real-time processing.

Analytical storage. ClickHouse and columnar databases for reports over billions of rows in seconds. ETL pipelines from any source.

API platforms. REST and gRPC with versioning, rate limiting, OpenAPI documentation. Gateways, authentication, audit.

How we work

  1. Audit. Profile the current system, find bottlenecks. Report with a plan in 2–3 weeks.
  2. Architecture. Service, data and flow diagrams agreed with your team.
  3. Implementation in sprints. Each sprint delivers a measurable result: a service in production, a metric improved.
  4. Load testing and launch. Tested on a production copy, rolled out in stages, monitored.

Stack

Go, Rust for critical paths, Node.js, PostgreSQL, ClickHouse, Redis, Kafka, NATS, Kubernetes, Prometheus and Grafana, OpenTelemetry.

Questions & answers

01When does a business need high-load engineering?+

When the service slows down or fails as traffic grows, the database is the bottleneck and adding servers no longer helps. Or when you plan for tens of thousands of concurrent users in advance.

02Do you rewrite existing systems?+

Yes, usually as a gradual migration: the most loaded parts of a monolith are extracted into separate services without stopping the business.
