Legacy application modernisation: a phased roadmap
Modernise a legacy application with dependency mapping, baseline evidence, bounded replacements, migration checks and explicit retirement criteria.
Speed, SEO, and refactoring sprints that make your product measurably better.
We run focused improvement sprints on live products — fixing performance bottlenecks, refactoring problem areas, and boosting search visibility.
Products with performance issues impacting user retention or SEO rankings
Teams with accumulating technical debt slowing down feature delivery
Founders wanting a high-impact audit and fix cycle before fundraising
What is included in a standard engagement. The final scope is agreed during discovery.
Tangible artifacts delivered at the end of the engagement.
Phases and durations for a standard engagement.
Comprehensive audit, metric baselines, and issue prioritization.
Quick wins: image optimization, caching, metadata, and easy refactors.
Deeper refactoring, database optimization, and architecture improvements.
Measure improvements, document changes, and provide future roadmap.
Choose a slow or risky business journey and define the improvement before changing frameworks. Keep migration reversible where feasible.
Measure latency, errors and cost under a recorded workload.
Replace a bounded component with compatibility tests and rollback criteria.
Compare equivalent workloads and verify data before expanding the change.
A look at how we've helped clients build, launch, and improve their products — with context on the problem, our approach, and what shipped.
Tell us about your project and we'll come back with scope, timeline, and a clear estimate.
