Full-stack engineer, six years in production with no gaps — multi-sided marketplaces, delivery and field operations, commerce platforms and configurators, and now multi-tenant SaaS with production LLM systems on top. Laravel/PHP · Python/FastAPI · Next.js/TypeScript. Shipped for clients in seven countries; led a 6-developer Laravel team 2023–2025.
Portfolio → abbasdd.github.io — every project names the layer I actually built, because most of the work below lives in private client and product repos.
A multi-tenant AI sales agent for consumer brands: RAG over each brand's own catalog (LangChain + FAISS), conversational ordering end to end into WooCommerce, and GPT-4o vision for customer-sent product photos — across ~7 tenants and 5 messaging channels. Beside it, the CRM over 1M+ customers: identity resolution, segmentation, loyalty tiers, and WhatsApp/SMS campaigns with delivery-receipt reconciliation. Laravel 12 + Python/FastAPI + Next.js.
Multi-sided marketplaces and field-operations platforms for clients in Oman, Qatar, UAE, Ghana, Canada and New Zealand. Booking and dispatch, wallets and payments, realtime tracking, bilingual EN/AR with RTL, and the REST APIs behind companion mobile apps.
