Services

A Full-Spectrum Suite of Modernisation Services

Application Assessment & Strategic Advisory

We begin with a deep-dive assessment of your legacy systems-analysing code quality, architecture, integrations, security posture, and business dependencies. Our consultants provide:

  • Technical & Business Gap Analysis: Identifying what works, what doesn’t, and what’s holding you back.
  • Modernisation Roadmap: A clear, phased plan outlining quick wins, long-term goals, and measurable milestones.
  • Risk & Cost-Benefit Analysis: Transparent insights to help you make informed decisions.

Rehosting & Replatforming (Lift-and-Shift)

If your legacy applications are stable but stuck on outdated infrastructure, we offer seamless rehosting and replatforming:

  • Cloud Migration: Move to AWS, Azure, or Google Cloud with minimal code changes.
  • On-premise to Hybrid: Shift workloads to hybrid environments for flexibility and cost savings.
  • Performance Optimisation: Enhance speed, reliability, and scalability.

Refactoring & Rearchitecting

Transform monolithic, hard-to-maintain applications into modern, modular architectures:

  • Microservices Adoption: Break down monoliths for agility and easier scaling.
  • Code Refactoring: Clean up legacy code for maintainability and future enhancements.
  • API Enablement: Expose core functionalities via RESTful APIs for easier integration.

Cloud Enablement & Integration

We help you unlock the full potential of cloud-native technologies:

  • Containerisation (Docker, Kubernetes): Deploy applications faster and more reliably.
  • Serverless Computing: Reduce operational overhead and only pay for what you use.
  • Seamless Integrations: Connect with CRM, ERP, and third-party services for a unified digital ecosystem.

Custom Software Development & Enhancement

When off-the-shelf solutions fall short, our engineers build custom modules or entirely new applications to fill the gaps:

  • Bespoke Application Development: Tailored solutions for unique business needs.
  • Legacy Extension: Add new features while maintaining core stability.
  • User Experience (UX) Modernisation: Refresh interfaces for better usability and accessibility.

Ongoing Support, Maintenance & Optimisation

Modernisation doesn’t end at go-live. We provide:

  • 24/7 Monitoring: Proactive issue detection and resolution.
  • Performance Tuning: Continuous improvements for speed, stability, and security.
  • Regulatory Compliance: Ongoing updates to meet evolving standards (GDPR, HIPAA, PCI DSS).
