I am a Senior Software Engineer & Systems Architect specialized in multi-tenant SaaS platforms, backend engineering, ERP/CRM integrations, and production-grade RESTful APIs. I translate complex business operations into resilient, high-performance software.

At Bander Trading Company, I architected and deployed a multi-tenant logistics platform serving 7,000+ active delivery agents with real-time WebSocket vehicle mapping, alongside Evix ERP integrations for 500+ corporate subscribers. My database and Redis queue optimizations reduced API latency by over 40%.

I also build AI-driven automation pipelines using modern LLMs (Azure OpenAI, Gemini) to extract structured ledger data from unstructured documents, automate ZATCA e-invoicing workflows, and enable natural language business querying.
