Who It's For

For organizations that demand reliability

When business continuity is imperative, we ensure infrastructure stability.

FinTech

Critical transaction systems requiring absolute precision and zero tolerance for errors.

Healthcare

High-availability infrastructure compliant with regulations for sensitive patient data protection.

SaaS Platforms

Robust multi-tenant architectures designed for global scaling and optimal performance under load.

Enterprise Organizations

Legacy system modernization and complex integration solution implementation.

IoT & Edge

Distributed systems for managing millions of connected devices and real-time data processing.

High-Traffic Systems

Systems optimized for handling extreme traffic loads and sudden traffic spikes.

What We Deliver

Engineering excellence behind the scenes

The invisible work that makes everything else possible.

System Architecture

Microservices, event-driven, and serverless architectures. The right architecture for your needs.

Reliability Engineering

SLOs, SLIs, and error budgets. Our approach is systematic when building reliable systems.

Observability

With logs, metrics, and traces, you have clear visibility into everything happening in your system in real-time.

Automation

Infrastructure as code, automated deployments, and self-healing systems.

Security Architecture

Zero-trust approach, encryption, and access control ensure security built into every system layer.

Performance

Profiling, optimization, and tuning for the best possible performance.

Core Principles

Our engineering philosophy

Foundations on which we build resilient and sustainable systems.

01

Fault-Tolerant Design

We assume components will fail. We build systems with built-in redundancy that automatically handle failures without service interruption.

02

Complete Automation

We eliminate repetitive manual processes. We implement automated deployment, testing, and operational processes for maximum efficiency.

03

Observability First

You can't optimize what you don't measure. We instrument every system segment for complete visibility and rapid diagnostics.

04

Flexibility & Evolution

Business requirements change. We develop modular architectures enabling easy upgrades and adaptation to new needs.

05

Security at Every Layer

Security isn't an add-on — it's a foundation. We integrate security protocols into every development phase and every architecture layer.

2

Architecture & Design

Designing scalable architecture with focus on high availability, security, and fault tolerance.

3

Implementation & Automation

Infrastructure as Code (IaC) development, CI/CD process setup, and rigorous automated testing.

4

Monitoring & Optimization

Monitoring system implementation, proactive alerting, and continuous performance tuning.

FAQ

Answers to technical questions

Details about our methodology and engineering practices.

While DevOps primarily focuses on software delivery agility and CI/CD processes, system engineering encompasses holistic architecture design, scalability, reliability, and long-term system sustainability. Our approach integrates both disciplines.

Absolutely. We specialize in infrastructure modernization. We conduct detailed analysis to identify current issues, eliminate technical debt, and transform existing systems into modern, scalable architecture.

We apply SRE (Site Reliability Engineering) practices including SLO/SLI metric definition, error budget management, chaos engineering, and automated incident response procedures.

While technology-agnostic, we have deep expertise in the Cloud-Native ecosystem: Kubernetes, AWS/GCP/Azure, PostgreSQL, Redis, Kafka, and modern observability tools.

We follow Security by Design and DevSecOps principles. Security is integrated into every step — from threat modeling and static code analysis to automated security checks and compliance standards.

Yes, knowledge transfer is a key part of our engagement. Through pair programming, detailed documentation, and dedicated workshops, we ensure your team can independently manage new systems.

We offer two engagement models: hourly billing for specific interventions and ad-hoc consulting, and a continuous monthly retainer that ensures proactive maintenance and system stability. Retainer arrangements start from approximately €2,500/month depending on infrastructure complexity and support level.
