Deployment speed versus traditional methodologies

Core Engineering

Architecture and development of mission-critical cloud-native applications that scale to millions of global users with sub-millisecond response times.

99.9%

Uptime on Managed Cloud Infrastructures

Cloud Architecture (AWS / Azure / GCP)

We design immutable infrastructures with Terraform, blue-green deployments on Kubernetes and microservice networks with service mesh (Istio). Every component is auto-scalable and self-healing.


Custom B2B Software

Enterprise applications built on hexagonal architectures and DDD, with RESTful and gRPC APIs, ERP integration (SAP, Dynamics) and legacy system connections without friction.


System Integrations & API-First

We connect your digital ecosystem: payment gateways, logistics platforms, CRMs and internal tools under an API-First model that enables unlimited future extensibility.


Digital Experience

We design interaction flows based on neuroscience and analytical retention. B2B interfaces and mobile apps that convert, not just impress.

45%

Average Increase in Interface Conversion

iOS & Android: Native & Hybrid

React Native and Expo for aggressive time-to-market, or Swift/Kotlin when native performance is non-negotiable. BLE vehicle control, scanners and offline geolocation.


High-Conversion Web UX/UI Portals

Angular SSR, Next.js and Vite to build B2B portals with perfect technical SEO (Core Web Vitals), PWA offline-first and real-time analytics dashboards.


Technical SEO & Performance

Lighthouse audits with Score 100, Server Side Rendering, static pre-rendering, structured data (JSON-LD) and semantic content strategies to dominate SERPs.


Cognitive IT

RAGs, intelligent agents and on-premise LLMs. We boost your company's efficiency by injecting AI on your corporate data without compromising privacy.

70%

Reduction in Information Search Time

GenAI & Private On-Premise LLMs

We deploy Llama, Mistral and Qwen directly on your infrastructure with Ollama. Total data sovereignty, GDPR compliance and zero dependency on external APIs.


Intelligent Automation (RPA + AI)

We combine Robotic Process Automation with language models to automate document workflows, contract validation, email classification and repetitive processes.


Data Engineering & RAG Pipelines

LlamaIndex, ChromaDB and semantic vectorisation of millions of documents. We build ingestion, indexing and retrieval pipelines that feed precise corporate chatbots.


Cyber Resilience

Military-grade shielding for IT infrastructures. Pentesting, end-to-end encryption and Zero-Trust governance for companies that cannot afford a security breach.

100%

Compliance in HIPAA and ENS Audits

Strategic Security & Zero Trust

We design perimeter IAM architectures where every request is independently authenticated and authorised. Granular RBAC, SSO with SAML/OIDC and 24/7 access auditing.


Infrastructure Audits & Pentesting

Static code analysis (SAST), dynamic (DAST), dependency scanning with Grype/Syft and complete Red Team intrusion simulations following OWASP methodology.


DevSecOps & Supply Chain Security

We sign every artifact with Sigstore/Cosign, generate automatic SBOMs, OPA policies in CI/CD and block merges with critical CVEs. Security isn't a sprint, it's the pipeline.


How We Work

Engineering with Purpose.

We're not a code factory. Every project goes through a deep discovery process where we understand your business, map critical flows and design the optimal architecture before writing a single line.

01

Architecture First

Every system starts with a rigorous architectural design. We document ADRs, C4 diagrams and API contracts before the first sprint.

02

Test-Driven Quality

Unit, integration and E2E test coverage. CI/CD pipelines that block merges if quality drops below the threshold.

03

Total Observability

OpenTelemetry, Grafana and proactive alerts. We know exactly how your system performs in production, in real time.
