We engineer high-performance IT systems built for scale

package adminguidefunc AdminGuide() []string {return []string{"system architecture", "highload backend", "data engineering", "mobile platforms", "secure infrastructure",}}

We start at the architecture and stay through production. Performance, failover and scaling go in at the foundation, so growth becomes a capacity plan instead of an emergency.

    AHEGAO Kit — infrastructure administration

    An infrastructure administration platform: backup, network inventory and storage upkeep through pluggable kits.

    A self-hosted administration platform: one PostgreSQL, one compose file, no outbound connections. Capability is added through kits — database backups verified by restore, a network diagram, artifact storage upkeep. Metrics are exported to Prometheus and Zabbix, and backups are written to a local path, NFS/SMB or S3.

Technology

Stack and resilience

Where the money flows, we use languages built for load. The infrastructure is your own, tied to no outside cloud.

Expertise
Architecture consulting
We work with any technology — rare, unusual, outdated. We join a project in any language, review the architecture, close vulnerabilities and connect the client's old systems to the new ones — without «let's rewrite everything».

We don't follow trends We build foundations

Guarantees

Not promises — decisions built into the architecture

99.99%

Resilience

Critical components are made redundant at the infrastructure level and spread across independent nodes or sites. When one component fails, load moves to the standby, so a failure does not become an outage.

100%

Proven recovery

Redundancy is not finished until the full recovery scenario has been tested. We rehearse restoring the system from backups regularly, so recovery follows a proven process instead of starting with troubleshooting in the middle of an incident.

1M+

Load testing

We test the system above its designed load and establish the limits of its performance in advance. Bottlenecks are found and removed before launch, not after users run into them.

24/7

Continuous monitoring

We monitor metrics, logs and the state of critical components continuously. Signs of degradation are caught before they turn into failure: the problem should reach engineers before it reaches users.

N+1

Capacity headroom

We do not design a system at the edge of its capacity. Resource and architectural headroom is planned in advance, so growing load stays a normal mode of operation rather than a reason to rebuild the infrastructure in a hurry.

0

No hidden dependencies

Critical architecture has to be understandable and manageable. We surface implicit links between components, record the key architectural decisions and remove the dependencies that make a system unpredictable under change.

Monitoring

What watching a system looks like

Grafana, Prometheus and Loki keep metrics, load and logs under observation in real time. Below is a simplified visualization of how that monitoring works in practice.
