End-to-end development with React, Next.js, Vue, or any framework that fits your needs. Server-side rendering, edge caching, and global CDN delivery.

iOS & Android Native Apps

Native and cross-platform mobile apps using React Native or Swift/Kotlin. App Store optimization, push notifications, offline support.

Progressive Web Apps (PWA)

Installable, offline-capable web apps with native-like performance. Ideal for enterprise tools and B2B dashboards.

E-Commerce & Marketplace Platforms

Custom storefronts, payment integration (Stripe, PayPal, SEPA), inventory systems, and real-time order management.

Service 02

Custom Software Engineering

Off-the-shelf software rarely fits enterprise needs. We design and build powerful custom systems — tightly integrated with your workflows, built on proven architecture, and engineered to last.

SaaS Platform Development

Multi-tenant architecture, subscription billing, onboarding flows, usage metering, and feature-flagged releases.

CRM & ERP Systems

Custom-built CRM and ERP tailored to your exact business processes — not generic tools you mold your team around.

API Development & Third-Party Integration

REST and GraphQL APIs, webhooks, OAuth, payment gateways, ERP connectors, and bi-directional data sync.

AI-Powered Features & Automation

LLM integration, intelligent document processing, predictive analytics, and automated decision workflows.

Legacy System Modernisation

Strangler-fig migrations, API layer extraction, and gradual re-platform without service disruption.

Service 03

Cloud & Infrastructure

We design, build, and operate cloud infrastructure that scales automatically, self-heals, and meets enterprise compliance requirements — all hosted within the EU by default.

Cloud-Native Architecture

Serverless, containers, managed databases — right-sized for your workload with cost controls built in from day one.

Kubernetes & Container Orchestration

Production-grade Kubernetes clusters, Helm chart management, auto-scaling, and zero-downtime deployments.

Infrastructure as Code (Terraform / Pulumi)

Reproducible, versioned, auditable infrastructure. Every resource tracked, every change reviewed.

CI/CD Pipeline Engineering

Automated build, test, security scan, and deploy pipelines using GitHub Actions, GitLab CI, or your preferred toolchain.

Private EU Infrastructure

Sovereign, GDPR-compliant infrastructure on our own servers in Frankfurt and Paris — no US cloud exposure.

GDPR-First by Default

Every infrastructure deployment defaults to EU data residency. No personal data ever leaves German or French data centres unless you explicitly require it.

Consulting Engagement Types

01

Architecture Review

A structured audit of your current system — we identify bottlenecks, risks, and quick wins. Delivered as a written report within 2 weeks.

02

Technical Due Diligence

Pre-acquisition or pre-investment code and infrastructure assessment. Risk scoring, debt analysis, and executive summary.

03

Fractional CTO

Ongoing strategic technology leadership — roadmap planning, vendor evaluation, team hiring, and board-level reporting.

04

Cloud Migration Strategy

Lift-and-shift vs. re-architect analysis, migration roadmap, cost modelling, and hands-on execution support.

Service 04

Architecture & Consulting

Strategic technical guidance from engineers who have built and scaled real enterprise systems. We help you make better decisions faster — whether you are starting from scratch or untangling years of accumulated complexity.

System Architecture Design

Microservices, event-driven, domain-driven design — we architect systems that survive years of growth without a rewrite.

Security Architecture & Threat Modelling

Zero-trust network design, OWASP compliance review, penetration test coordination, and remediation planning.

Technical Due Diligence

Investor-grade code and infrastructure review. Risk scoring, tech debt quantification, and executive-ready reports.

Engineering Team Scaling

Hiring frameworks, technical interview design, onboarding playbooks, and engineering culture consulting.

How We Work

A Proven Delivery Process

Refined across hundreds of enterprise projects. Predictable, transparent, and built for your success.

01

Discovery & Scoping

We deep-dive into your goals, constraints, and existing systems — then produce a detailed project blueprint and fixed-price proposal.

02

Architecture & Design

System architecture, data model, API contracts, and UX prototypes — built collaboratively with your team before a line of code is written.

03

Agile Development

Two-week sprints with automated testing, code reviews, and live demos at every milestone. You always know where things stand.

04

Launch & Operate

Production deployment, load testing, 24/7 monitoring, and ongoing managed support. We stay engaged long after go-live.
