Legacy System Modernisation in Leeds

A monolith becomes harder to change as it grows. Each update carries risk of breaking unrelated features, deployment windows stretch, and hiring developers who want to work on it gets harder. Microservices let you update, scale, and deploy pieces independently. The upfront cost is real, but so is the cost of staying stuck with something that slows your business down.

We plan migration in stages, not a big bang cut-over. Data mapping is validated against your source systems before any production move. We run parallel systems during transition, test rollback procedures, and keep detailed audit trails. Your team signs off each phase before we move forward.

Yes. We use techniques like strangler pattern (routing requests gradually to new services) or dual-write approaches (new system gets data alongside old one) to avoid downtime. It's slower than an outage-based cutover, but you stay operational while we work. The choice depends on your business risk tolerance and timeline.

This is common. We spend time with your team and domain experts tracing how the system actually works, not just what the docs say. We write tests to capture that logic, then refactor against those tests. It costs time upfront but prevents expensive surprises later.

Our teams in Spain and Ukraine work in or near UK timezones, so handovers are quick and overlap is built in. You get continuity without the cost of full London or Leeds salaries. Your CTO or IT Director can attend planning calls and reviews without scheduling around 8-hour gaps.

We hand over a system your team can maintain, with clear documentation and runbooks. Many clients then move to a support retainer for ongoing updates and scaling. Others take it in-house. We stay available for big architecture questions or new features, but the goal is your independence.
