• Cross-cutting solution and enterprise architecture authority across application modernisation, cloud foundations, DevOps/platform transformation, data, and AI — reporting to the SVP of Architecture & Cloud Platform.
• Served 100–500 engineers across multiple business units; sat on the Architecture Review Board as the cloud and platform voice; authored NFR frameworks, business cases, and governance standards shaping multi-year engineering roadmaps.
• Application Modernisation: Led architecture for cloud-native applications across active-active API platforms, service decomposition, event-driven integration, asynchronous processing, Lambda + Step Functions workflows, container platforms, adapter patterns, and operational readiness.
• Golden Path Delivery: Built traceability-enabled application golden paths with standardised adapter-based implementation patterns, CI/CD, infrastructure provisioning, contract testing, quality gates, automated API documentation publishing, and release automation adopted by engineering teams.
• Cloud Foundation & Network: Designed and governed AWS Control Tower and Azure landing zone foundations account/subscription structure, SCPs, identity federation, hub-spoke Transit Gateway topology, Direct Connect/VPN, centralised egress, DNS resolution, and firewall policies.
• Modernisation Programmes: Defined reusable migration and re-platforming patterns used across 8+ projects; led flagship migration of 500+ microservices from a legacy VM-based estate (single-AZ, manual ops, cloud capabilities unused) to cloud-native AWS with active-active architecture, blue/green deployments, automated failover, and zero customer-facing downtime over 12 months.
• Cost Architecture: Drove ~80% cloud cost reduction on the flagship workload through architecture decisions - right-sizing, replacing over-provisioned VMs with container/serverless patterns, Fargate Spot, scale-to-zero, reserved capacity planning, and identifying top cost drivers during rearchitecting.
• Delivery Modernisation & IDP: Standardised CI/CD patterns, repository onboarding, deployment automation, quality gates, and environment strategy; built an Internal Developer Platform enabling self-service infrastructure and governance for 40+ engineering teams, compressing release cycles from weeks to days.
• Architecture Governance: Defined cloud adoption roadmap, ARB review practices, reference architecture library, NFR guidance, Well-Architected reviews, and executive-aligned decision support across reliability, security, cost, and operability.
• Data Platform: Architected TB-scale S3 data lake and near-real-time streaming pipeline Kinesis Firehose Glue/Spark S3 Athena Redshift reducing reporting latency from hours to minutes.
• AI Architecture: Led AWS Textract production rollout for document intelligence; led a team of 2-4 to deliver enterprise RAG system with ingestion pipeline, vector indexing, semantic retrieval, response grounding, and LLM orchestration on Azure OpenAI and Azure AI Search.
