Legacy modernisation
Big-bang rewrites rarely survive contact with production payroll. We prefer strangler patterns, bounded contexts, and measurable cutovers backed by comparison tests.
Characterisation
Golden datasets, shadow reads, and parity checks reduce “looks fine” risk before write traffic moves.
Incremental boundaries
Each increment keeps a rollback path. Data migrations use expand/contract or phased dual-write when needed.

Practical notes We bias toward artefacts that survive handover: decision logs, threat assumptions, test evidence, and rollback scripts. That discipline reduces “tribal knowledge” risk when teams rotate or vendors change.
If your environment has sovereign, sectoral, or contractual constraints, bring them into the first workshop—not as footnotes at acceptance. Early mismatch on data residency, key custody, or change windows is the dominant source of rework.
Questions teams ask on first review How do you bound scope when discovery is incomplete? We split work into milestones with written assumptions and exit criteria. Unknowns are recorded as explicit risks with owners and review dates—not as silent padding inside estimates.
What artefacts do you expect from our side? A systems inventory with owners, network and identity diagrams where they exist, and a plain-language data classification summary accelerate meaningful review. Access to non-production environments is helpful but not a substitute for written constraints.
How are production changes controlled? Peer review or automated checks, named approvers for high-risk paths, and traceable tickets aligned to releases. Emergency changes still produce post-incident notes and follow-up tasks.
Do you provide 24/7 operations? Unless contracted, response is on Australian business-day cadence with agreed severities. After-hours incident support should be explicitly scoped, including escalation contacts and evidence expectations.
What teams tell us after delivery Composite themes from Australian enterprise and cross-border programmes—we do not attribute quotes to named clients on this marketing site.
Engineering finally had one reconcilable story with finance on cloud spend because tagging, budgets, and variance notes were wired into the same monthly export. Head of Platform, regulated industry Rollback stopped being a debate. Release records, canary gates, and feature-flag owners were written down before go-live, which shortened incident review.
