Build, Modernise, Integrate, and Run Your Enterprise Applications
Enterprise applications are the backbone of your operations. We deliver the full application lifecycle — new development, legacy modernisation, third-party integration, performance optimisation, and managed support — keeping your business-critical applications reliable, secure, and aligned with your evolving needs.
We have taken over hundreds of applications from other vendors. Our approach starts with a thorough code and architecture audit — understanding the system before making any changes — and transitions responsibility smoothly with minimal disruption to your team.
- Full application lifecycle — new build, modernisation, integration, and managed support
- OWASP security standards built into every application from day one
- Performance engineering — optimised for real load with monitoring that catches issues early
- Cloud-native architecture — API-first, microservices-ready, and horizontally scalable

New enterprise applications built to your exact specification and workflow requirements.
Application Modernisation
Legacy application re-architecture using modern cloud-native patterns and frameworks.
Application Integration
API and middleware-based integration connecting applications across your enterprise stack.
Performance Engineering
Application profiling, load testing, and systematic performance improvement for critical systems.
Security Assessment & Hardening
OWASP Top 10 compliance review, penetration testing, and vulnerability remediation.
Application Support & AMS
Managed application support with SLAs, release management, and proactive monitoring.
Use Cases in Production
Real deployment patterns — the specifics vary per client, but the structure stays the same.
EnterpriseApplication Modernisation for a Legacy Java Platform
A business-critical Java application built in 2008 was running on an unsupported Java 6 environment. Every feature request took 3 months due to technical debt. The risk of the system failing with no path to recovery was acute.
Phased modernisation: Java 6 to Java 17 migration, architectural decomposition into 4 bounded services, containerisation on Docker, and CI/CD pipeline implementation.
- Java version upgraded without business disruption in 3 phases
- Feature delivery cycle from 3 months to 3 weeks
- System stability improved — zero unplanned outages in 12 months post-modernisation
HealthcareManaged Application Support for Healthcare Software
A healthcare software company needed a reliable managed support partner for their patient records application serving 80 GP practices — with SLAs that matched clinical operational requirements.
Managed application support with P1 15-minute response SLA, scheduled maintenance in off-peak windows, security patch management, and quarterly architecture reviews.
- P1 SLA met in 100% of incidents over 18 months
- Security vulnerability window reduced — patches applied within 48 hours of release
- Internal team freed to focus on new product development
