Do you always recommend a full rewrite?

No. We assess whether incremental modernisation (strangler fig pattern), partial rewrite, or full rewrite is the right approach based on your system's complexity, business risk, and timeline. Most projects benefit from an incremental approach.

How do you ensure business continuity during migration?

We run old and new systems in parallel with automated comparison testing. Each migration phase is validated before the next begins. Rollback plans are in place at every stage.

What tech stacks do you modernise from and to?

We've modernised from .NET, Java/J2EE, PHP, legacy Python, COBOL interfaces, and monolithic architectures to modern cloud-native stacks (TypeScript, Python, Go, React, Next.js, microservices, serverless).

How long does a typical modernisation take?

It depends on system complexity. Using AI-accelerated engineering, we compress what would traditionally be 12-18 month projects into 3-6 months. We scope clearly after the audit phase.

Legacy Modernization

Migrate from legacy systems to modern, AI-ready architecture, without the risk.

$150k - $300k12 to 16 weeks

We modernise legacy applications, monoliths, and outdated tech stacks into cloud-native, API-first, maintainable systems. Using AI-accelerated engineering, we compress multi-year migration projects into months while preserving business continuity.

Who it's for

Built for teams that need this now

This service was designed around a specific kind of problem. If any of these sound like your team, you're in the right place.

CTOs with aging tech stacks

Running critical business systems on outdated frameworks that are increasingly difficult to maintain

Engineering leaders planning migrations

Who need to modernise without disrupting ongoing operations or losing business continuity

Operations teams

Dealing with performance, reliability, or scalability issues caused by legacy architecture

Common triggers

Signs you need this

Most teams come to us after one of these moments. Recognise any of them?

Every new feature takes 3-5x longer because of legacy code complexity

You can't hire engineers who want to work on your current tech stack

Your system can't scale to support your current growth trajectory

Security vulnerabilities in deprecated frameworks are creating compliance risk

Integration with modern services and APIs is increasingly painful

Recognise two or more of these?
