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.
Balady Billing System
Canonical microservices ensemble for government-integrated payment processing, points conversion, and wallet management — saga-style compensation, dual-verification on every callback, and circuit breakers on every external dependency.
Balady+ Mini-Apps Platform
Container-based mini-apps with a permission-bridge runtime, a multi-stage CI/CD pipeline, and a two-tier identity model (basic OTP / high-assurance SSO) with per-app, mini-app-scoped encryption keys.
Reference Data Management
Single governed source-of-truth for translations and cross-system code mappings. Transactional outbox + RabbitMQ Streams for cache-invalidation only; MongoDB + Redis read-through; BFF page-level aggregation; mobile offline bundle.
Commercial Licenses Dashboard
Real-time monitoring platform for government employees across Saudi municipalities. A replayable event stream feeds two purpose-built read models — search/KPIs and spatial — so each query class runs on the engine best suited to it.
Notification Hub
Centralized notification platform — ingest → templating → per-channel dispatch (SMS / mobile / web) with persist-before-dispatch invariants, bounded retry, and per-channel queue isolation.
Centralized DB Decomposition
Platform-level proposal decomposing a shared database into per-business-domain stores via Debezium CDC + Kafka, with phased migration and Grafana / Prometheus monitoring.
Campaign Central
Centralized campaign management for Balady Business merchants — lifecycle, subscriptions, AI-driven recommendations (mediated by a Sanitisation Service for PDPL compliance), POI + GIS integration, notifications, analytics.
POI Platform & Event Distribution Hub
Centralized Points-of-Interest system with multi-precision geohash + Redis geospatial cache. The EDH counter-proposal routes change events through Apigee for PDPL filtering, consent validation, attribute redaction, and commercial-terms enforcement.
Balady BNPL Integration
Buy-Now-Pay-Later integration with a leading Saudi bank in the Unified Payment Page. Multi-provider architecture with signed-webhook security stack (HMAC-SHA256, IP allow-list, replay protection, idempotency) and encrypted single-use presigned URLs.
No case studies in that year.
