Expert AI Engineer | AI Agents, AI Automations, LLMs, RAG | Full Stack

Lahore, Pakistan - 2:34 am local time
I build AI agents, document AI pipelines, and RAG systems on production data, with full-stack engineering (Python, React, AWS) to take them from architecture to a live platform.

I work deeply with Claude, Claude Code, and MCP for agent architectures. I have also shipped production LLM features on OpenAI, Gemini, LangChain, and RAG pipelines. The stack choice depends on the problem, not on what I feel like using.

WHY WORK WITH ME:
📊 Top 1% Upwork Talent, 5 Star Rating, 100% Job Success
✅ AI Agents, LangGraph, LangChain, RAG Systems, and LLM Integrations taken from architecture to production, still live and earning
✅ Full ownership end to end, backend, frontend, AI pipelines, and deployment, all handled directly by me
✅ Proven across industries: document AI for retail, multi-agent automation for marketing, warehouse-scale data pipelines for Metro Cash & Carry, and full-stack platforms for construction
✅ I tell you upfront what's realistic to build and how long it'll actually take, whether it's a two-week integration or a multi-month build

WHAT I BUILD:

📄 1. AI Document Intelligence & RAG Systems
Structured extraction from unstructured supplier data (emails, spreadsheets, PDFs, ZIP archives) using LLM-based parsing, multimodal vision extraction reading catalogue numbers and barcodes off product photos, deterministic guardrails that stop models from hallucinating identifiers, hybrid retrieval with LLM reranking (pgvector, HNSW), and semantic entity resolution across a 49,000+ record catalogue.

🤖 2. Multi-Agent Systems & Automation
Multi-agent LLM pipelines (Claude, OpenAI, Gemini, Groq) running keyword research, content generation, image generation, and ad campaign deployment end to end for a marketing agency, with prompt-engineered agents handling task routing and decision-making across the full workflow. Live in production and generate $15K+ MRR with zero manual intervention.

🏗️ 3. Enterprise Data Pipelines
Warehouse-native data pipelines (BigQuery, GCP Dataform) built for Metro Cash & Carry, one of Europe's largest wholesalers, turning multi-country credit scoring into a self-configuring, config-driven system. Processing 2.8M + records per country entirely in-warehouse, with new-market onboarding reduced from a development project to a config file and a CSV upload.

💻 4. Full-Stack SaaS Development
End-to-end products from first sketch to live platform for a rebar manufacturer, integrating AI and LLM features directly into production applications: React/Next.js frontends, Python/Django/FastAPI backends, PostgreSQL/MongoDB data layers, deployed on AWS with Docker and CI/CD. Generated $30M+ in orders and 1,000+ active users in its first month, and earned a spot in a construction-tech incubator program.

MY STACK:

AI/LLM: Claude, OpenAI, Gemini, Groq, RAG, pgvector (HNSW), DSPy, multi-agent orchestration, prompt engineering, LLM extraction, multi-provider model routing, semantic search, fal.ai, zbar, Ideogram

Backend: Python, Django, FastAPI, Node.js, Celery, RESTful APIs, SQLAlchemy, Alembic, WebSockets, JWT Authentication

Frontend: React, Next.js, TypeScript, Tailwind, Konva.js, Vite, shadcn/ui, TanStack Query

Database: PostgreSQL, MongoDB, Redis, BigQuery, MSSQL

Infra: AWS, AWS Lambda, AWS Amplify, Docker, Kafka, Elasticsearch, CI/CD, GCP Dataform, GCP Cloud Run, GCP Cloud Functions, Looker Studio, DigitalOcean

Integrations: Playwright, Discogs API, MusicBrainz API, SpyFu API

Development Tools: Claude Code, MCP, Cursor, Git, GitHub Actions

Building something with AI agents, need a document AI pipeline that handles messy real data, or scaling a full-stack SaaS product? Tell me what you're working on, happy to talk through how I'd approach it.
