Mohammad Irshad

AI & Backend Engineer

I design the systems that don't make the screenshot — the APIs, pipelines, and LLM infrastructure that stay up while traffic, cost, and complexity try to take them down.

About

Engineer across the full AI + backend stack

I'm an AI & Backend Engineer with 3+ years building production-grade platforms end to end — from scalable Node.js/NestJS backends and Next.js frontends to generative-AI microservices.

I've shipped multi-vendor marketplaces, e-commerce and delivery systems with real-time chat and video, payments, logistics and ZATCA-compliant invoicing, and engineered RAG pipelines, LLM assistants and computer-vision systems on top of OpenAI and AWS. I care about clean, secure, maintainable architecture that turns complex requirements into reliable products.

Where I've worked

AI & Backend Engineer · Bawabat

Jun 2025 — Present

Dammam, Saudi Arabia

  • Engineered a multi-vendor marketplace & logistics platform with a modular NestJS/TypeScript backend spanning 35+ domains (providers, businesses, listings, orders, cart, coupons, reviews, logistics, shipments, campaigns, moderation).
  • Built real-time chat (Ably) and audio/video calls (Agora) with Firebase push notifications for live order and messaging updates.
  • Integrated AWS end to end — S3 & CloudFront for media, SES for email, and Comprehend/Translate for multilingual (EN/AR) content; secured with JWT, Google OAuth2, and RBAC.
  • Shipped two more products: OxygenLenses (eyewear e-commerce on Express + Drizzle, Next.js storefront + drag-and-drop admin) and Rider (e-commerce + delivery on MongoDB with ZATCA-compliant QR e-invoicing and PDF invoices).
Current

AI Engineer · Luminous Rays LLC

Aug 2024 — May 2025

Remote, United States

  • Built a Retrieval-Augmented Generation (RAG) recommendation engine using OpenAI embeddings and Pinecone for semantic search across 10,000+ listings.
  • Developed a multi-modal GPT-4o-mini chatbot with persistent MongoDB history, Whisper voice-to-service transcription, and GPT-4 Vision image moderation.
  • Architected a multi-modal dispute-resolution system producing automated verdicts with confidence scoring, exposed via a Dockerized FastAPI microservice.

AI Engineer · IR Solutions

Jan 2024 — Jul 2024

Islamabad, Pakistan

  • Built a YOLO + OpenCV pipeline to automatically remove car-image backgrounds via segmentation, masking, and contour post-processing.
  • Developed a hospital assistant chatbot with RAG over a medical knowledge base and OpenAI Function Calling for appointment scheduling.
  • Deployed REST APIs over Stable Diffusion for parameterized text-to-image generation and a photo-mosaic image application.

AI Engineer · Stallions.AI

Jun 2023 — Dec 2023

Islamabad, Pakistan

  • Built an interactive financial-metrics dashboard (Streamlit/Python) computing key metrics and visualizing trends with Matplotlib/Seaborn.
  • Engineered a generative-AI financial chatbot with web retrieval, prompt engineering, similarity search, and multi-turn memory.
  • Developed a face-similarity retrieval system using OpenCV and FaceNet/ResNet embeddings indexed in Pinecone for fast top-N matching.

Split a sprawling marketplace into 35+ bounded domains so orders, logistics and moderation could evolve without stepping on each other.

Flagship platform with a modular NestJS backend across 35+ domains — providers, businesses, listings, orders, cart, logistics and shipments — plus real-time chat (Ably), audio/video calls (Agora), Firebase push, AWS media & email, multilingual EN/AR content, and Next.js customer web + admin portal.

Gave non-technical staff a drag-and-drop admin so the catalog and storefront layout are merchandised without a deploy.

End-to-end eyewear store: an Express + Drizzle ORM backend with JWT auth, image uploads and Mailjet email, a Next.js storefront, and a drag-and-drop admin dashboard built with dnd-kit and shadcn/ui for catalog and content management.

Built ZATCA-compliant QR e-invoicing into the order flow so every sale is tax-correct the moment it's placed — not reconciled later.

Commerce + delivery system on a Node.js/Express + MongoDB backend with AWS S3 storage and Firebase push. Implemented ZATCA-compliant QR e-invoicing and automated PDF invoices for Saudi tax compliance, with a Next.js storefront and a feature-rich MUI admin panel.

Treated each model as an isolated FastAPI service with its own memory and confidence scoring — so a bad verdict is observable and contained, not silent.

A Dockerized FastAPI suite powering a marketplace: a RAG recommendation engine (OpenAI embeddings + Pinecone) over 10k+ listings, a GPT-4o-mini assistant with MongoDB memory, Whisper voice-to-service, GPT-4 Vision moderation, and a multi-modal dispute-resolution engine with confidence-scored verdicts.

A run of focused proofs — each one taking a single AI capability (retrieval, detection, generation) from notebook to a callable API.

A collection of earlier applied-AI builds: a hospital RAG chatbot with function-calling appointments, YOLO + OpenCV car background removal, Stable Diffusion text-to-image APIs, a generative-AI financial assistant with web retrieval, and a FaceNet + Pinecone face-similarity retrieval system.
