I am the founder of Al Sadq IT Solutions LLC (Dubai, UAE) and the lead architect of BYBRetail ERP — a production-grade, enterprise retail management platform built from the ground up for retail, distribution, and supply chain businesses across the Middle East.
My journey started from hands-on IT support and infrastructure, progressed through Cisco networking and Windows Server administration, and evolved into full-stack enterprise software architecture. I bring together deep technical foundations with real-world business operations experience to build ERP systems that actually work.
I am a logical thinker who takes full ownership of problems until they are fully resolved — from network infrastructure to complex inventory costing engines and double-entry accounting systems.
Enterprise Retail + Distribution ERP — Built for scale, accuracy, and real operations.

A context-first UI/UX skill for Claude Code — inspects a real codebase, derives navigation, layout and density before visual style, retrieves a small bundle of verified guidance and verifies by rendering.

- Coverage: web · mobile (SwiftUI, Compose, Flutter, React Native) · desktop (WinUI, WPF, Avalonia) · TV (Android TV, tvOS, Tizen / webOS) · kiosks
- Engine: zero-dependency Python — BM25 + structured retrieval over 248 hand-written records and a 114-concept ontology, typed platform evidence, criticality-ordered bundle selection, three-layer output
- Evaluation discipline: cases written before code, pre-registered thresholds, five blind held-out sets scored by independent sessions, four frozen-build real-project rounds (32 tasks / 16 codebases in the last one), every defect routed to its earliest wrong layer
- Verification loop: Playwright renders for web, kiosk and TV-web; HTML twins for native stacks; first-render vs final defects recorded per task
