Architecture
Systems Architecture Design
Architecture at WTJ Consulting LLC starts with evidence. We interview the teams who operate each system, inventory the integrations nobody documented, and sample how data truly flows across the estate. Only then do we describe a target structure with named boundaries, interface contracts and explicit ownership. The design is written so that a new engineer can understand not just what was chosen, but why every alternative was set aside.
Deliverables typically include a current-state dependency map, a target architecture with phased sequencing, interface specifications, non-functional requirements for availability and performance, and a decision register. We also mark the risky assumptions plainly, so leadership can invest with open eyes rather than optimistic diagrams.
- Current-state discovery and dependency mapping
- Target architecture and boundary definition
- Interface contracts and failure assumptions
- Phased roadmap with cost bands and trade-offs

Integration
Enterprise Integration Engineering
Integration engineering connects finance, operations, customer and logistics platforms so information arrives complete, on time and in a form the receiving system can use. We favour durable patterns: event streams for timely state changes, message queues for load levelling, governed APIs for controlled access, and scheduled jobs only where batch logic genuinely fits. Each interface ships with retry behaviour, dead-letter handling and a reconciliation report written for business owners.
We also care about the human side of integration. When a connection fails at two in the morning, the on-call engineer needs a runbook, a clear escalation path and enough context to act without waking the original author. Contract tests guard every interface, so a change on one side cannot silently break the other.
- Event streaming and message queue design
- Managed API gateways and access governance
- Idempotent batch pipelines and reconciliation
- Contract tests, monitoring and operational runbooks

Cloud
Cloud Infrastructure Modernisation
Moving to the cloud without reshaping a workload mostly relocates the old problems. Our modernisation work proceeds in deliberate stages. We begin with instrumentation so the migration is guided by real utilisation data, then containerise the services that benefit from portability, move stateful systems on their own schedule, and retire the accumulated configuration debt that would otherwise follow the workload into its new home.
Infrastructure as code is the baseline rather than an aspiration. Every environment, from development sandbox to regulated production tenancy, is created from the same reviewed templates with identical guardrails. Cost management runs continuously alongside reliability: resources are tagged, measured and right-sized so the monthly bill tracks real demand instead of historical accident.
- Migration assessment and wave planning
- Containerisation and workload reshaping
- Infrastructure-as-code environment baselines
- Cost governance, tagging and right-sizing

Data
Data Platform Engineering
A data platform is only valuable when people trust the numbers it produces. We design ingestion, transformation and serving layers that record lineage at every hop, so any figure on a report traces back to its source record. Warehouses, lakehouses and operational stores are modelled as one coherent estate rather than competing projects, with shared definitions held in version control and reviewed like code.
Adoption depends on the smaller details as much as the architecture. Freshness indicators, data quality alerts, clear ownership labels and a small set of governed self-service models do more for confidence than an elaborate catalogue nobody opens. We build those first, then extend the platform as real questions arrive.
- Ingestion, transformation and serving layer design
- End-to-end lineage and data quality monitoring
- Dimensional and activity-schema modelling
- Governed self-service models and metric definitions

Security
Cybersecurity Compliance Reviews
Compliance fails when it becomes a paperwork exercise. Our reviewers test the controls that are claimed, interview the people who operate them, and inspect the logs that should prove they worked. Identity and access management, privileged access, logging coverage, backup integrity, encryption in transit and at rest, and third-party exposure are assessed together because in practice they fail together.
Findings are ranked by genuine business impact rather than by checklist order, and each one arrives with a practical remediation path and an effort estimate. Where formal frameworks matter, we map evidence to the standards your customers and regulators recognise, then help you keep that evidence current across the year instead of scrambling the week before an audit.
- Control testing and evidence verification
- Identity, access and privileged account review
- Logging, backup and resilience assessment
- Risk-ranked findings with remediation planning

Operations
Managed Technology Operations
Systems drift after launch unless someone is watching. Our managed operations service keeps monitoring, patching, backup verification, certificate renewal and incident response on a predictable rhythm, with service levels written in language both engineers and executives can read. Incidents follow a defined escalation path, and every resolution produces a short, blameless record that improves the next response.
Each month you receive an operational record describing what changed, what was detected and what was improved. That transparency keeps the estate legible to leadership and makes it easy to see whether the investment is holding its value. Managed operations works well as a long-term home or as a bridge while an internal team grows into the responsibility.
- Monitoring, alerting and on-call response
- Patch, certificate and backup management
- Defined service levels and escalation paths
- Monthly operational reporting and improvement
