Risk that can be acted on
A shared view of fragile dependencies, data exposure, operational bottlenecks, security gaps, and the workflows that cannot be interrupted.
Audit · Rebuild · Migrate
Modernise the system without losing the business inside it.
Replace fragile software, recover the rules hidden inside it, and move critical workflows through a staged migration the business can survive.
Best for
Teams whose product has become slow to change, expensive to operate, difficult to trust, or constrained by an architecture that no longer fits the business.
Legacy software is rarely just old code. It contains years of pricing rules, operational exceptions, customer promises, manual workarounds, and integrations that no diagram captures. Replacing it safely starts with understanding which behaviour is intentional, which complexity can disappear, and where failure would interrupt revenue or operations.
We turn that understanding into migration boundaries. New services and interfaces are introduced around real business slices, with compatibility, data reconciliation, observability, and rollback designed before traffic moves. The aim is not architectural novelty. It is a simpler system that can change faster while the existing business keeps running.
A credible target system
Architecture tied to business boundaries, team ownership, operating constraints, and an explicit reason for each new piece of complexity.
A migration path with exits
Sequenced releases, compatibility boundaries, reconciliation, rollback conditions, and measurable proof before the next critical path moves.
A platform the team can run
Clear services, observable behaviour, documented operations, controlled infrastructure, and fewer places where only one person knows what happens.
What we cover
The work behind a result your team can own.
- 01
System and workflow audit
Code, infrastructure, data, integrations, incidents, support patterns, operational workarounds, and the business rules behind them.
- 02
Target architecture
Domain boundaries, ownership, service and deployment topology, interface contracts, security model, and non-functional requirements.
- 03
Incremental replacement
Strangler migrations, compatibility layers, API facades, parallel runs, feature controls, and staged traffic movement.
- 04
Data transition
Schema redesign, migration rehearsal, transformation, reconciliation, dual writes where justified, cutover, and rollback planning.
- 05
Reliability and performance
Load and failure testing, bottleneck removal, tracing, metrics, alerting, recovery procedures, capacity, and cost visibility.
- 06
Operational transfer
Infrastructure as code, deployment pipelines, runbooks, architecture records, incident paths, team pairing, and removal of obsolete components.
Understand
We inspect the running system and follow real work through it, combining code and infrastructure evidence with the exceptions known by operations and support.
Plan
We choose a first business slice, define the target boundary, migration and compatibility strategy, proof criteria, data plan, and rollback conditions.
Replace
New paths run beside old ones where possible. We reconcile behaviour and data, observe production traffic, and move responsibility in controlled steps.
Transfer
We complete cutover, retire what is no longer needed, tighten operations, document the new baseline, and make ownership explicit inside the team.
How we make decisions
Practical rules for keeping the work honest.
Recover behaviour before simplifying it
We distinguish accidental complexity from business rules so the rewrite does not quietly remove something customers or operators depend on.
Migrate in business slices
A complete workflow is easier to prove and operate than a horizontal technical layer that cannot deliver value on its own.
Operations shape the architecture
Deployment, observability, data recovery, access, and incident response are design inputs—not work postponed until cutover.
The engagement
Enough structure to move quickly. Close enough to make decisions.
Typical shape
2–4 week audit followed by a staged delivery programme
Core team
Technical lead · 2–4 engineers · Product/design as workflows require
Working rhythm
Weekly migration review plus evidence from each production slice
From your side
A system owner, operational experts, and access to code, data, and telemetry
Not a fit for
A big-bang rewrite with no safe migration path, a technology refresh with no accountable system owner, or an architecture exercise disconnected from the running business.
