• Eliminated critical production bottlenecks and transformed manual factory operations by building
robust, real-time tracking modules tailored for complex Inventory, Procurement, Sales, and Production
workflows.
• Delivering 100% system uptime and guaranteeing strict client data privacy by designing an isolated,
database-per-tenant infrastructure utilizing Docker and deployed entirely on AWS (EC2, Route 53).
• Driving the strategic product expansion into a scalable enterprise solution by actively architecting the
backend transition of the core ERP into a multi-tenant SaaS platform.
• Accelerated feature delivery and streamlined developer onboarding by integrating AI-assisted workflows
(Gemini, Jules, Antigravity), automated CI/CD pipelines, PHPUnit testing, and dynamic VitePress documentation.

• Awarded Top Performer of (2024) for demonstrating extreme ownership, driving cross-team
collaboration, and taking the initiative to resolve critical blockers across undocumented legacy systems.
• Resolved a highly escalated client crisis within a single week by independently learning on-premise
hardware integrations to completely refactor a severely flawed database architecture, eliminating race
conditions and data loss.
• Guaranteed the legal operation of pharmaceutical clients across the GCC by developing the core data
pipelines that accurately reported millions of daily medication movements to national government tracking
systems (Tatmeen, SFDA, NHRA).
• Eliminated thousands of hours of manual warehouse labor by building a custom Chrome extension that
bypassed blind receiving (the forced scanning of individual medicine boxes) by automatically pulling the full
digital shipment hierarchies directly from the government portal.
• Protected database integrity and drastically reduced system latency by leading a full upgrade from Laravel
5 to 10, normalizing bloated JSON columns, and replacing fragile SFTP uploads with robust RESTful APIs.

• Developed RESTful Laravel APIs to manage lifecycle events such as Commission, Ship,
Return, and Dispense
• Designed scalable MySQL schemas optimized for 2M+ record datasets, improving
performance through indexing
• Implemented EPCIS integrations via file-based and API-based channels with external
partners
• Improved file processing speed by adding size-stabilization checks and SFTP caching logic
• Migrated a legacy Laravel 5.4 application to Laravel 10 by building a new project with
refactored architecture
• Managed server operations including releases, maintenance, updates, supervisor config,
and cronjob setup
• Worked in a remote agile environment using Jira, Bitbucket, and Git; actively participated
in sprint cycles and code reviews
