Building Practical AI-Coded Products from Real Business Problems.
I'm Shajjad Khan, a hands-on founder, product thinker, and AI-assisted builder. I do not pretend to be a traditional manual coder; I turn real business problems into clear instructions for AI coding systems, then test, refine, and deploy practical software that people can actually use.
TawreedFlow توريد
The modern multi-tenant procurement and supply chain SaaS purpose-built for luxury hotels and enterprise hospitality across the GCC (Saudi Arabia, UAE, Qatar).
TawreedFlow Enterprise
The Industry Challenge
Hospitality properties in the GCC process millions in monthly food, beverage, engineering, and operational requisitions. Traditional operations relied on chaotic, un-audited WhatsApp chats and fragmented spreadsheets, resulting in lost quotes, procurement leakage, and lack of compliance with financial controls.
The Architectural Solution
TawreedFlow creates a single source of truth across the entire procurement lifecycle. Requisitions flow seamlessly through Department Heads, Purchasing Coordinators, and Financial Directors. Automated RFQs dispatch directly to vetted suppliers, enabling instant quotation comparison with item substitute flags and purchase order delivery verification.
Enterprise Role-Based Access
Engineered with strict tenant isolation supporting multi-property hotel chains: Master Admins, Directors, Purchasing Receivers, Department Heads, and external Supplier Portals (Owners, Admins, Field Drivers).
"Designed, directed, tested, and shipped by solo founder Shajjad Khan using AI-assisted coding workflows, transforming enterprise hospitality purchasing across GCC hotels."
Selected Systems & Platforms
A collection of AI-assisted platforms, practical tools, and workflow systems shaped by Shajjad Khan from real operational pain points.

- Role-based self-service employee portal and departmental audit logging.
Building with Founder Mindset and AI
I build by explaining the problem clearly, guiding AI coding tools, checking the output against real business needs, and improving it until it works in production. My strength is not memorizing syntax; it is product judgment, workflow thinking, testing, and persistence.
Business Context First
Every architectural decision connects directly to operational efficiency, user satisfaction, and tangible ROI.
AI-Assisted Execution
I use AI as a coding partner: I define the feature, review the behavior, catch broken flows, and keep improving the product until it solves the real problem.
Full-Lifecycle Ownership
From listening to end users on hotel floors and network operations centers to shaping data, screens, automations, deployments, and support flows with AI-assisted development.
