Do we have to rewrite everything at once?
No. We modernise in stages, one module or service at a time, so critical systems keep running while the platform improves underneath.
Modernise your legacy systems without stopping the business
Overview
The problem isn’t your old code. It’s the tightly coupled architecture, scattered logins and brittle integrations that make every change slow and risky. We fix that in stages (assess, re-architect, integrate, secure), so your platform gets faster, safer and easier to change while critical services keep running.

What We Deliver
From the first assessment to the last migrated module, we modernise your application estate in staged, low-risk steps, and keep it performing after go-live.
01
Release one part without risking the whole We break large, tightly coupled applications into independently deployable services, one module at a time, so your teams ship faster, scale what’s busy and stop fearing every release. Our work includes:
- Application portfolio discovery
- Current-state architecture review
- Risk and dependency mapping
- Staged modernisation roadmap
02
A second opinion before you commit Not ready for a full programme? Our architects review your current design, pressure-test your plans and give you clear, prioritised recommendations, with no build team attached. Our work includes:
- Architecture and design evaluation
- Target-state architecture design
- Refactor vs. rebuild vs. replace guidance
- Security and scalability review
03
Release one part without risking the whole We break large, tightly coupled applications into independently deployable services, one module at a time, so your teams ship faster, scale what’s busy and stop fearing every release. Our work includes:
- Domain-driven service decomposition
- Incremental strangler-pattern migration
- Independent deployment for every service
- Testing and security validation at each stage
04
Make old and new systems work as one Clean, secure APIs connect your legacy platforms, cloud services and third-party tools, so data flows reliably and every new system plugs in without another custom patch. Our work includes:
- API-first integration architecture
- Legacy-to-cloud and third-party connectors
- Secure API gateway patterns
- Audit logging on every integration point
05
One login. Every system. Full control. Scattered logins frustrate users and weaken security. We centralise identity with OpenID Connect and OAuth 2.0, so people sign in once and access is governed consistently across every application. Our work includes:
- Single sign-on across applications
- Centralised identity with Keycloak and OIDC
- Role-based access control design
- Integration with your existing identity provider
06
Decouple systems so each one scales on its own We replace brittle point-to-point calls with event-driven messaging, so services react in real time, absorb traffic spikes and fail without taking others down with them. Our work includes:
- Event-driven design with Kafka and RabbitMQ
- Asynchronous service communication
- Caching and data store optimisation
- Resilience patterns for graceful failure
07
Ship modernised apps the modern way Modernised services run in containers on Kubernetes with automated CI/CD, so releases stop being big, risky events and become routine. Full cloud migration and infrastructure sit with our Cloud & SecOps team. Our work includes
- Containerisation with Docker
- Kubernetes orchestration
- CI/CD pipelines for every service
- Encryption in transit and at rest
08
Keep modernised systems fast, stable and improving Automated regression testing on every release, recurring load and performance checks, and full-stack monitoring keep your platform healthy as it grows. We stay on to modernise the remaining modules, step by step. Our work includes:
- Automated functional and regression testing
- Load, stress and performance testing
- Application and infrastructure monitoring
- Incremental modernisation of remaining modules
How We Work
Critical services stay live while we modernise one module at a time
Every programme starts with a proof of concept in 3–4 weeks, before you commit to scale.
We prioritise by business impact and risk, not by which system is oldest.
OIDC identity, role-based access, encryption and audit logging built into every layer.
Banking & Financial Services
API layers over core platforms and single sign-on across banking systems.
Insurance & Healthcare
Legacy core and secure integrations, while critical services stay live.
Retail & E-Commerce
Modernised order, inventory and backends that scale with demand.
SaaS & Technology
Monoliths broken into services that scale and ship independently.
Enterprise & Government
Identity consolidation and staged modernisation of critical systems.
Manufacturing & Logistics
Real-time tracking and automated workflows for efficient operations.
FAQ
Can you just review our architecture first?
Yes. Our technical advisory engagement gives you an architecture review and design guidance without committing to a full build.
How fast can we see something real?
A modernisation roadmap in 2–3 weeks, a target architecture in 2–4 weeks, and a working proof of concept in 3–4 weeks. Full production migration typically takes 3–6 months, depending on legacy complexity.
Do you also build new products?
Yes. See our Product & Application Engineering services. This page covers modernising the systems you already run.
What happens after launch?
We stay on. Ongoing support covers regression testing, performance monitoring, incident support and continuous enhancements, under service levels agreed with you.
How are engagements priced?
Scoped to your goals, from a fixed-price assessment or advisory engagement to phased delivery and ongoing support. Talk to our team for a tailored quote.
