A systems engineering firm built around one promise: it stays up.
Nika S.A is a technology services company headquartered in Yerevan, Armenia. We design, build, and operate the high-concurrency platforms behind real-time gaming, payments, and digital commerce — systems where downtime, lag, or a single mis-counted balance is not an option. Our team works in the parts of engineering most teams never have to think about: peak-load architecture, real-time data, and transaction integrity at scale.
Senior by default
You work with engineers who have built and operated systems at scale — not a rotating bench of juniors learning on your platform.
Accountable for outcomes
We measure success in uptime, latency, and correctness — the numbers your business is judged on — and we own them with you.
We hand it back
Every engagement leaves your team with the code, the documentation, and the knowledge to run and extend what we built.
The people accountable for your platform
A small, senior team — you'll know exactly who is building your system.
Aram Petrosyan
Founder & CEOTwo decades building and scaling backend platforms, the last ten focused on real-time systems under heavy concurrency. Aram founded Nika to bring senior, accountable systems engineering to operators who can't afford downtime.
Lilit Hovhannisyan
CTODistributed systems and data infrastructure specialist. Lilit has designed streaming and transaction platforms processing billions of events a day, and leads Nika's engineering practice, architecture standards, and reliability culture.
Davit Sargsyan
Head of ReliabilityAn SRE at heart, Davit owns how the platforms we build stay up. He sets the SLOs, runs the game-day exercises, and leads the 24/7 on-call practice that keeps client systems steady through peak load.
