Enterprise IT SolutionsCHANGE-CONTROLLED
Software that has to work
with everything you already run
Enterprise work rarely starts on a blank page. There is a core system nobody will replace, a release window on the last Saturday of the month, and an access review every quarter. We build inside the estate you already have — integration, migration, access and audit — and we plan the rollout as carefully as the code.
- Integration with systems you can't replace
- Change control and release windows
- ISO 27001 Compliance Support
- ERP & CRM integration
- Identity & access
- Data migration
The work around the software is usually the harder part
A new system in a large organization rarely fails on features. It fails because the data did not come across cleanly, because the cutover landed in the same week as month-end close, or because nobody could get the access they needed on day one. So we start with the estate rather than the roadmap: what talks to what today, which system is the record for each entity, which boxes cannot be touched and who signs off before anything ships. Migrations are rehearsed against production-shaped data before the real run. Changes go through your change process and your release window, with a rollback that has been tested rather than assumed. Access rules, approvals and audit trails are agreed before go-live, not retrofitted after the first audit finding. Engagements run as a defined project with a cutover date, or as an ongoing service with scope agreed in the contract — whichever matches how your organization buys.
The work we take on inside an estate
Six things organizations usually need from an outside team: the integrations, the migrations, the access controls and the maintenance that decide whether a system actually lands.
Application Maintenance & Support
Someone has to own the systems already running. We take over applications built by other people: read the codebase, write down what was never documented, clear the backlog of small breakages, and keep runtimes and dependencies current so the upgrade happens on your schedule instead of being forced by an end-of-support date.
- Monitoring & alerting
- Performance work
- Runtime & version upgrades
MaintenanceDevOpsCI/CDERP & Core System Work
Whether the core is SAP, Oracle or something built in-house a decade ago, most of the work sits at its edges — custom modules, the reports finance will actually sign off on, and interfaces to systems it was never designed to talk to. Replacing the core is one option we cost out, not the default answer.
- Custom modules & reports
- Supply chain, HR & finance interfaces
- Phased rollout by site or unit
SAPOracleCustom ERPAutomation & Applied ML
Forecasting, document extraction, classification and routing, applied to processes that already exist and already generate data. We agree up front what a good answer looks like, measure against it, and keep a person in the loop wherever a wrong answer is expensive to unwind.
- Forecasting & anomaly detection
- Document extraction
- Workflow automation
LLMsMLOpsRPAIntegration Between Systems
The point where enterprise programs usually stall. We map what talks to what, settle which system is the record for each entity, then build the interfaces — synchronous APIs where latency matters, queues where it doesn't, and the nightly file drop where the far end has no API and never will.
- REST & GraphQL interfaces
- Queues & event streams
- Batch & file-based transfer
RESTGraphQLKafkaContinuity & Recovery
Backups you have actually restored from, not just taken. We agree recovery objectives with the people who own the process, design failover to match them, write the runbook, and then rehearse it — a recovery plan nobody has run is a document, not a plan.
- Backup & restore testing
- Failover design
- Runbooks & rehearsals
RTO/RPODRPHA ClustersAccess, Audit & Compliance Support
Who can see what, who approved it, and what the log shows when an auditor asks. We build role models, joiner-mover-leaver flows and audit trails, and design systems to support the obligations you are already under. The frameworks in scope are agreed per engagement.
- Role models & access reviews
- GDPR & HIPAA support
- Audit trails & evidence

Not sure which part of the estate to change first?
Send us the shape of it — the systems, the constraints, the date you can't move — and we'll come back with where we would start and why.
What it takes to change
a system people are
already using
The difference between a rollout that lands and one that stalls is rarely the code. It is whose approval you need, which week you are allowed to ship in, and what happens to the people who have to work differently on Monday morning.
Cover for the Hours That Matter
Support windows are written into the contract rather than implied by a badge. We agree which systems need cover outside office hours, what counts as a P1, who gets called and how quickly we answer — then staff to that. Where the schedule is genuinely continuous, we say so and price it.
Costs You Can Predict
Rates, run costs and the cost of the change itself, estimated before work starts and revisited whenever scope moves. You get the working rather than a percentage: what an engagement costs, and what dropping a piece of scope would save.
Automation Where It Pays Back
Not every manual step is worth automating. We look at volume, error cost and how often the process changes, then automate the handful of workflows where the payback is obvious and leave the rest alone.
Rollout Treated as a People Problem
A system goes live for one region or one business unit at a time, with the old path still available while people learn the new one. Training material, super-users and a first-week support desk are planned alongside the code, not after it.
You Hear About Problems From Us
Monitoring and alerting are set up so we see incidents before your users report them. Every P1 gets a written root-cause note, and the standing review covers what broke, what changed and what is queued next — not a slide of green ticks.
Kept Current, Deliberately
Frameworks, runtimes, libraries and certificates all expire. We track what is approaching end of support, schedule upgrades into ordinary release windows, and keep the estate from reaching the point where a security patch forces an unplanned migration.
Newer technology, judged by what it has to fit into
These are the five we get asked about most. Each is worth doing where it solves something the current estate cannot — and we will say so when it doesn't.
Cloud Computing
Migration, One Slice at a TimeMoving workloads to AWS, Azure or GCP with the route back to on-premises systems designed first. Landing zones, identity federation, cost visible per team, and an honest list of the workloads that should stay where they are.
AWSAzureGCPMulti-CloudBlockchain
Records Shared Between PartiesNarrow but real: several organizations need the same record and none of them will host it for the others. Permissioned ledgers, smart contracts, provenance and settlement — and a straight answer when a signed database would do.
HyperledgerEthereumSmart ContractsAI and Automation
Pointed at Existing ProcessesDocument classification and extraction, forecasting, and assistants that answer from your own content. Most of the engineering is in the data pipeline, the evaluation set and the access rules; the model is rarely the hard decision.
LLMsRPANLPPredictive AIConnected Devices and IoT
Plant, Fleet and Facilities DataGetting telemetry off machines, meters and vehicles into somewhere it can be queried: device identity, ingest that survives a lost connection, edge processing where bandwidth is scarce, and retention agreed with whoever pays for storage.
GCP IoT CoreMQTTDigital TwinVR and Immersive Interfaces
Training and SimulationHeadset training for procedures that are expensive or unsafe to rehearse for real, plus product and facility walkthroughs. Worth it when the alternative is taking equipment out of service — a good video wins most other cases.
UnityWebXRHoloLensAR Training
The Layer Underneath
Whatever sits on top, these are the things every engagement ends up needing
Zero-Trust Access Controls
Identity as the perimeter rather than the network: MFA, role-based access, privileged access handled separately, and verification at each hop instead of trust inherited from the subnet.
Service Boundaries That Hold
Domain-driven boundaries, a service mesh (Istio/Linkerd) where the traffic justifies one, Kubernetes for orchestration and a gateway in front. We split where teams need to deploy independently, not by default.
Data Platforms and Analytics
Warehouses and lakes, ingestion from the operational systems, and reporting people actually trust — because the definition behind each number is written down and agreed.
Modernising Legacy Systems
Strangler-fig migration: a façade in front of the old system, one capability moved behind it at a time, both paths running until the last caller has moved across.
Systems That Talk to Each Other
iPaaS, message brokers and event-driven flows connecting SAP, Salesforce, Oracle and the systems built in-house — with retries, dead-letter handling and reconciliation designed in from the start.
Governance and Audit Readiness
ITIL-aligned change management, environments and approval gates that match your policy, and audit trails and reporting designed to support the regimes you are subject to.
From estate walkthrough to a cutover that holds in six steps

Estate Walkthrough & Scope
We sit with the people who run the systems and map what is actually there: what talks to what, which interfaces were never documented, which servers nobody is allowed to touch, and where the data we will need really lives. Out of that comes a scope, an order of work, and the constraints everything else has to fit inside.
Integration & Migration Plan
Before any code: interface contracts, the system of record for each entity, and how much history comes across — in what shape, cleaned by whom, signed off by which team. Migration is planned as a rehearsal against production-shaped data first, then a real run with a rollback that has been tried.
Design Around the Work People Do
Interface design starts from how the job is done today, including the spreadsheet someone keeps on the side because the current system can't handle it. Screens are walked through with the people who will use them every day, before development starts.
Build in Your Environments
Development runs against your environments, your branching model and your CI, with work landing behind feature flags where it can — so what is shipped and what is switched on stay separate decisions. You see the same board and the same build status we do.
Testing, Security Review & UAT
Functional and load testing, a security review, and user acceptance run by your own people against real scenarios. Whatever your change process asks for — test evidence, sign-offs, a back-out plan — is produced as part of the work rather than chased in the week of the release.
Cutover, Hypercare & Handover
The switch happens inside your release window, with a tested rollback and a named person on each side. The first weeks after go-live are staffed heavily on purpose. Then documentation, runbooks and open items are handed over, and we either step back or continue under an agreed support scope.
Different estates, different constraints
What an integration has to respect — a regulator, a franchise agreement, a broadcast schedule, an audit trail somebody will read — changes with the sector. These are the ones we work in.
- 8 Industries
- Integration-led
- Migration planning
- Remote or on-site
HRMS
Payroll, applicant tracking and performance tooling that has to sit alongside the finance system and the identity directory — with joiner-mover-leaver flows matching how HR and IT actually hand work to each other.
PayrollATSPerformanceMarket Research
Panel management, survey tooling and reporting, including the awkward part: reconciling respondent data across sources and keeping personal data out of the places it should never reach.
BISurveysAnalyticsFood & Restaurant
POS, inventory and multi-site reporting for chains, where head office wants one number and every location has a slightly different setup, a patchy connection and a franchise agreement limiting what you may change.
POSInventoryMulti-locBanking & Finance
Digital channels, risk and regulatory reporting built around a core banking system nobody is replacing this decade. The work is interfaces, reconciliation and change that survives an audit.
Core BankingRiskIFRSTelecom
BSS/OSS work, provisioning and subscriber management: high volume, long-lived contracts, and billing logic that has collected exceptions for years and cannot lose one of them in a migration.
BSS/OSSBillingNMSMedia and Broadcast
Content management, rights and scheduling, and the delivery infrastructure behind them. The broadcast schedule fixes the deadlines, so releases are planned around it rather than the other way round.
OTTDRMCMSFitness & Wellness
Membership, class scheduling and instructor tooling across sites — including the ones still running the system the group acquired rather than chose, which usually have to keep running through the migration.
MMSSchedulingAnalyticsE-Learning
LMS platforms for corporate training and mandatory certification: SCORM and xAPI content, completion records that hold up when someone asks for evidence, and SSO into whichever identity provider the organization already runs.
