Our expertise

Four engineering practices and a transverse security and sovereignty axis: from infrastructure to shipped product.

Infrastructure & Platform Engineering

A foundation that holds under load.

We design and operate robust platforms from Day 0 to run: landing zones, container orchestration, distributed systems, SRE. Hyperscalers when they make sense, European bare metal when it cuts the bill — sizing is an engineering decision, not a fate.

Kubernetes, K3s, OpenShift and containers
Multi-cloud: AWS, GCP, Azure, Scaleway, DigitalOcean, Hetzner
On-prem and bare metal — sovereignty and cost control
Landing zones: Day 0, Day 1, Day 2
Infrastructure as Code and GitOps: Pulumi, Terraform, Ansible, Helm, Flux
Distributed systems: high availability, scalability
Observability and monitoring (SRE): Prometheus, Grafana
FinOps: cost analysis, optimisation and reduction

Data & Analytics Engineering

Data you can actually rely on.

We build the data foundations that power your decisions and products: real-time or batch ingestion, transformation, governance and compliance. Architectures proven on demanding volumes.

Streaming, micro-batch and batch pipelines: Kafka, Flink
Orchestration and integration: Airflow, Airbyte, Temporal
Governance, quality and GDPR compliance
DataOps: industrialised data delivery
Analytics foundation and data activation
Stores: PostgreSQL, ClickHouse, Redis, MongoDB, Neo4j, Qdrant

AI & Machine Learning

Do more, with less.

We put AI where it produces measurable effect: business copilots, intelligent process automation, RAG over your data. And we master the full ML chain — from training to self-hosted, low-OpEx inference, including open-weight models.

Generative AI: LLMs, agents, RAG, business copilots
Process automation and orchestration (n8n)
ML engineering: PyTorch, TensorFlow, Jupyter, Nvidia CUDA ecosystem
Low-OpEx inference and training — self-hosted open-weight models (vLLM)
MLOps and AIOps: from prototype to model in production

Product & Digital Delivery

From idea to shipped product.

We build bespoke products and systems, and we run digital projects end to end for SMBs. Our credibility comes down to one fact: we publish digitalyser.io, our own SaaS platform, designed, built and operated by Breexio.

Bespoke development: Go, Python, JavaScript, TypeScript, Java, Rust
End-to-end digital project management for SMBs
Product engineering — proof in production: digitalyser.io
Application architecture and APIs

Transverse axis

Security & sovereignty

Security and ownership of your digital assets run through everything we build — from the CI/CD chain to where your data lives.

DevSecOps: security built into the delivery chain
Adversarial thinking: reason like the attacker
Technical due diligence and reverse engineering
Self-hosting and zero lock-in: your data, your stack
