Our Services —
What We Offer
High-performance engineering for enterprise-grade software systems. From architecture to operations, we handle every layer of your stack.
Service 01
Web & Mobile Development
We build high-performance web applications and native mobile apps that scale to millions of users. Every product is engineered for speed, reliability, and great user experience — from the first load to the hundredth release.
Full-Stack Web Applications
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.
Admin Dashboards & Internal Tools
Powerful back-office interfaces, data visualization, reporting engines, and workflow automation for ops teams.

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.
Infrastructure Technologies
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
Architecture Review
A structured audit of your current system — we identify bottlenecks, risks, and quick wins. Delivered as a written report within 2 weeks.
Technical Due Diligence
Pre-acquisition or pre-investment code and infrastructure assessment. Risk scoring, debt analysis, and executive summary.
Fractional CTO
Ongoing strategic technology leadership — roadmap planning, vendor evaluation, team hiring, and board-level reporting.
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.
Service 05
Managed Operations & SLA Support
We do not disappear after launch. GB Systems provides ongoing managed operations — monitoring, patching, incident response, and continuous improvement — so your team can focus on business, not infrastructure.
24/7 System Monitoring
Real-time alerting, on-call escalation, and full-stack observability with Prometheus, Grafana, and OpenTelemetry.
Security Patching & CVE Response
Automated dependency updates, CVE triage, and emergency hotfix deployment — typically within 4 hours of disclosure.
Backup & Disaster Recovery
Automated daily backups, point-in-time recovery, and tested DR runbooks. RPO < 1 hour, RTO < 4 hours.
Performance Optimisation
Continuous profiling, query optimisation, cache tuning, and load-test-driven capacity planning.
SLA-Backed Uptime Guarantees
Enterprise SLAs up to 99.99% uptime with financial penalties, full audit logs, and monthly status reports.
Dedicated Account Engineering
A named senior engineer who knows your system deeply — available via Slack, email, or phone during business hours.
Non-negotiables
Across Every Service We Deliver
These standards apply to every project we touch — no exceptions, no shortcuts.
Zero-Trust Security
Every service is authenticated, every request validated. No implicit trust — ever.
Multi-Region Redundancy
Your system runs across multiple locations. If one goes down, another takes over instantly.
Automated CI/CD Pipeline
Every update goes through automated build, test, and security scan before it reaches users.
Full Observability
Real-time metrics, distributed traces, structured logs, and instant alerting — always on.
Compliance-Ready
GDPR, ISO-27001, and SOC 2 built in from day one. Full audit trails included.
Performance-First
Load-tested, profiled, and optimised before every release. Speed is never an afterthought.
How We Work
A Proven Delivery Process
Refined across hundreds of enterprise projects. Predictable, transparent, and built for your success.
Discovery & Scoping
We deep-dive into your goals, constraints, and existing systems — then produce a detailed project blueprint and fixed-price proposal.
Architecture & Design
System architecture, data model, API contracts, and UX prototypes — built collaboratively with your team before a line of code is written.
Agile Development
Two-week sprints with automated testing, code reviews, and live demos at every milestone. You always know where things stand.
Launch & Operate
Production deployment, load testing, 24/7 monitoring, and ongoing managed support. We stay engaged long after go-live.
