Senior Back-end Developer
NUPCO
iNUPCO Task Workspace: Task, Incident & Workflow Management Platform
- Designed and led development of a Clean Architecture .NET 8 service (API / Application / Domain / Infrastructure) for enterprise task, incident, and workflow management across multiple teams and workspaces.
- Owned task lifecycle functionality — assignment, reassignment, space/team queue routing, due-date handling, and audit-logged status tracking.
- Architected the event-driven integration layer with a BPM engine and Kafka (consumers, producers, DLQ handling), enabling real time task-status synchronization across downstream modules.
- Improved task-list performance at scale by delivering optimized query paths (counts, reduced fan-out, sargable filters, cached lookups) and versioned APIs for safe side-by-side rollout.
- Exposed reusable task APIs so other INUPCO microfrontends can embed dynamic task lists, assignment, and reset-to-space flows without rebuilding core logic.
iNUPCO SRM — Supplier Onboarding & Lifecycle Management
- Participated in the design and development of the supplier onboarding workflow — pre-registration, profile completion, document upload, and multi-step internal review/approval — for both medical and non-medical supplier categories.
- Designed permission-based supplier profile lifecycle features: edit-profile requests, reviewer-facing change tracking, banking/IBAN data, category management, and declarations.
- Built the underlying API layer (FluentValidation, AutoMapper, JWT authentication, feature-flagged rollouts) on the same layered .NET architecture.
- Integrated compliance and operational tooling: Wathq commercial-registration verification, document-expiry handling, Excel import/export for supplier and user data, and Quartz-scheduled background jobs.
- Collaborated within a regulated procurement domain — roles, supplier user management, qualification/segmentation workflows — aligned with NUPCO's shared enterprise design system.

GISCON Middle East
Led development and maintenance of a suite of environmental monitoring applications for Kuwait's Environment Public Authority (eMISK), using .NET Web API on the back-end, React.js on the front-end, and Esri's JavaScript API for GIS/mapping functionality.
- Built eMISK Marine Water Quality from the ground up — a new application presenting real-time measurements from marine water and coastal monitoring stations along Kuwait's shoreline.
- Enhanced and extended eMISK Kuwait Air Quality with new features and functionality on an existing production system.
- Led a revamp of eMISK Drinking Water Quality, introducing new features for improved user experience and data accessibility.
