How I think about architecture, what I bring to a programme, and where I've done it.
Most architecture mistakes are made before the first line of code.
By the time a system is in production, the trade-offs are already in concrete — the cost of a wrong decomposition is measured in years, not weeks. So I spend my time at the front: ADRs and C4 diagrams as conversation tools, not write-once deliverables. If a decision can't be explained in one paragraph and one diagram, it isn't a decision yet.
Three opinions I hold strongly:
Microservices that share state are worse than one monolith. The Commercial Licence decomposition worked because we found the natural seams — a bounded context per business capability, from approval and licensing to location, invoicing, and safety permitting — before splitting code.
The Debts Hub started life as a REST callback flow. Synchronous callbacks gave weak delivery guarantees under load, so we switched to event-driven messaging over RabbitMQ. The lesson scaled across the platform: every gating integration in the Balady ecosystem now consumes events, not synchronous callbacks.
PDPL data masking, consent validation, and commercial-terms enforcement belong at the gateway, not in each consumer. The Event Distribution Hub counter-proposal was built on that principle.
The job is finding the right constraints early. Execution follows.
Each area is grounded in production work at NHCI and earlier engagements.
Architect for 10+ systems within the Balady citizen super-app and supporting platform services. Authored 11+ canonical HLDs, two governance frameworks (Architecture Contribution & Review; Technology Assessment & Decision), and the platform's Unified Logging Framework.
Cloud-native delivery for clients across banking (First Abu Dhabi Bank), retail (Nike), healthcare (Dubai Health Authority), and HR / SaaS (Panorama): monolith-to-microservices on OpenShift, PCI-compliant integration patterns, and IBM Watson SOA integrations. Also delivered an Oracle ERP (E-Business Suite) implementation for the telecom operator Orange.
Oracle EBS R11 → R12 upgrades; migration of Letter-of-Guarantee and Letter-of-Credit modules; Java + Oracle DB integration work and financial-data reporting.
