Engineering for systems that can't go down.

High-load, real-time platforms: systems that handle large volumes of concurrent users, move data in milliseconds, and process transactions where correctness is non-negotiable. We work with operators in entertainment, fintech, and digital commerce — anywhere the system has to stay fast and exact under pressure.

Both. We can embed senior engineers directly into your team, or take full ownership of a workstream and deliver it end to end. Most relationships start with a short, fixed-scope architecture review so both sides understand the system before committing to anything larger.

Always. You own the code, the infrastructure, and the documentation. We build with your team and hand over knowledge as we go — the goal is that your engineers can extend and operate everything we deliver without depending on us.

We're pragmatic and polyglot. Commonly Go, Rust, TypeScript/Node, and Java/Kotlin on the services side; Kafka, Redpanda, Flink, Redis, and Postgres for data and streaming; Kubernetes, Terraform, and the major clouds for infrastructure. We choose tools to fit your system, not the other way around.

We engineer for failure from the start: SLOs and error budgets, autoscaling, graceful degradation, load and chaos testing, and full observability with metrics, traces, and logs. For platforms that need it, we provide 24/7 on-call coverage and run game-day exercises ahead of peak events.

Nika S.A is headquartered in Yerevan, Armenia, with a senior engineering team that works in close timezone overlap with European, Middle Eastern, and Asian clients. You work directly with the engineers building your system.
