My deliverables are High-Level Designs that engineering organisations build from — every container labelled, every integration sequenced, every trade-off recorded as an Architectural Decision Record. Across the MENA region — Saudi Arabia, the United Arab Emirates, and Egypt — I have shipped this for government, banking, retail, and healthcare. Since joining the National Housing Company Innovation in 2024 I have authored more than eleven HLDs that are now the agreed architecture across multiple programmes.
I treat C4 diagrams and ADRs as living artefacts, version-controlled and re-rendered on every change. The platforms I design are typically built on Kubernetes and Apigee, with Spring Boot or ASP.NET Core on the application tier; RabbitMQ Streams, Apache Kafka, and Debezium CDC on the messaging tier; and PostgreSQL, Oracle 19c, MongoDB, and Elasticsearch on the data tier.
Selected case studies
A few of the most architecturally substantive systems I have led — each a full case study with a pattern-level diagram.
Commercial License Revamp
Decomposed a legacy government licence monolith into a modern microservices target across several DDD bounded contexts on Camunda BPMN/DMN — now the agreed target architecture across engineering.
Debts Hub
Centralized debts substrate gating Balady service issuance on outstanding-debt resolution. Replaced REST-based confirmations with event-driven messaging for stronger delivery guarantees, eliminating a class of failure.
DMS Migration (Hybrid-Cloud)
Multi-terabyte, multi-million-record migration from on-premise file storage to cloud object storage (in-region) using Strangler Fig with per-document backend-flag tracking — zero-downtime cutover.
