Technology & Architecture Consulting
Architecture-led delivery for regulated and high-scale platforms
We help organisations modernise legacy estates, design resilient cloud-native architectures, and deliver rapid proof-of-concepts that de-risk transformation—across payments, data platforms, and AI-enabled services.
- Payments platforms and transformations supporting £200B+ daily processing
- Global IoT and telecom platforms processing at 500,000+ events per second
- Real-time analytics estates processing 25 Petabytes daily events
- Real-time payments architectures delivering ~5,000 TPS and sub-0.5s latency
Services
Consulting and hands-on architecture support from strategy through pilots and delivery governance.
Enterprise & Solution Architecture
Target-state architecture, transition states, reference patterns, and decision governance to align delivery teams and stakeholders.
- Target-state and transition architectures
- Reference architectures, patterns, and guardrails
- Architecture governance and design authority support
Cloud Strategy & Modernisation
Cloud strategy and modernisation roadmaps for hybrid and cloud-native estates, including platform engineering direction and delivery standards.
- Cloud strategy (AWS/Azure/GCP; hybrid)
- Modernisation roadmap (monolith to modular/microservices)
- Platform engineering standards (Kubernetes, IaC, CI/CD)
Data Platform Strategy
Data foundations, governance, and platform direction to enable trusted reporting, real-time insights, and AI-ready data products.
- Data platform blueprint and operating model
- Streaming-first patterns (Kafka) and integration design
- Governance: lineage, quality, and controls
AI & GenAI Enablement
Practical AI architecture patterns and PoCs, including controlled integration of LLMs into business workflows.
- GenAI architecture patterns (RAG, orchestration)
- Controls: security, privacy, auditability
- Rapid PoCs with measurable success criteria
Banking, Payments & Regulatory Change
Architecture and delivery leadership across payments schemes and regulated banking environments.

Technology Assurance & Architecture Audit
Independent assessment of architecture decisions, delivery risk, and operational readiness.
- Architecture review and NFR gap assessment
- Delivery risk and dependency analysis
- Operational readiness: monitoring, support model, resilience

How we work
A delivery-minded approach designed to de-risk change and make architecture actionable.
-
Discover
Assess current state, constraints, risks, and value hotspots.
-
Define
Target-state architecture, key decisions, standards, and transition plan.
-
Prove
PoC or pilot to validate feasibility, security, performance, and delivery approach.
-
Deliver
Architecture leadership and governance through build, integration, and rollout.
-
Assure & evolve
Independent review, optimisation (resilience/cost), and continuous improvement.
