Background & Highlights

Meet Arbaz Khan

Hands-on Software Developer engineering production-grade web applications, custom ERPs, and automated business platforms since 2023.

Working actively in the software industry since 2023, I have contributed to production-grade web applications, multi-tenant ERP systems, CRM platforms, and real-time mobile backends.

I developed and maintained 4+ core business modules (Real Estate Billing, Inventory Management, Supply Chain, and Finance) within a multi-tenant ERP architecture using CodeIgniter 3 and MySQL. I engineered high-performance REST APIs integrated with a Flutter mobile app for real-time synchronization, implemented a granular RBAC system managing 7+ user roles, and tuned complex SQL queries to cut page load times by ~40%.

My work spans specialized business automation: from Logistics & Fleet Scheduling and automated Billing & Debt Recovery, to OCR Invoice Data Extraction that eliminates manual billing errors.
