I build...Fed up with manual workflows? I help startups and enterprises automate complex workflows and build scalable AI-powered web apps. I design and implement intelligent backend systems that integrate Large Language Models (OpenAI GPT-4, Claude, etc.), vector search (RAG), and automation agents with your stack. I build end-to-end AI Automation (document processing, CRM integration, lead scoring, automated reporting) using LLMs and Python. Create RAG search/QA systems over your proprietary data. Develop custom AI agents (with LangChain, LangGraph, CrewAI) that autonomously handle tasks. With YC-backed startup experience as a founding engineer, my Python/Django + React/Next.js solutions run at enterprise scale, processing 1M+ API calls/day and driving $50K+ ARR. I deliver results fast. I lead with transparency. You’ll see a working MVP in weeks, not months of planning. I provide clear timelines, code milestones and frequent demos. Before any contract, I’ll outline the right architecture and feasibility for you. Most importantly, if the tailored solution I deliver doesn’t meet your success criteria, I stand by a 100% money-back guarantee. Technology Stack ✔️ AI & LLM: OpenAI (GPT-4/GPT-4o), Claude AI, Mistral; LangChain/LangGraph; AI Agents and multi-agent orchestration; prompt engineering and fine-tuning; embedding models and evaluation. ✔️ RAG & Vector Search: Pinecone, FAISS, Weaviate, pgvector, Chroma; semantic search pipelines for document intelligence. ✔️ Python (Django, FastAPI, Flask); REST APIs, WebSockets; PostgreSQL: Celery & Redis ✔️ React.js, Next.js, TypeScript; UI frameworks (Bootstrap, Tailwind, MUI). ✔️ DevOps / Cloud: AWS, GCP, Docker, Kubernetes, GitHub Actions; Nginx, Cloudflare CDN; CI/CD pipelines, automated testing. ✔️ Data & Automation: Web scraping (Scrapy, BeautifulSoup), ETL pipelines, Pandas for data processing; integrations with third-party APIs/CRMs. Clients trust me to deliver results: I’ve been a founding/core engineer at YC-funded startups. My work has driven real outcomes (reduced process time, higher accuracy, revenue growth). One of my client said⭐⭐⭐⭐⭐ “I have never worked with a better freelancer. Hammad is extremely independent and keeps you updated with all progress.” I’d love to work with: ✔️ Tech Startups / SaaS Founders or teams adding AI automation or scaling their backend. ✔️ FinTech / HealthTech needing secure, compliant systems with AI-driven automation (e.g. finance tools, medical workflows). ✔️ Organisations seeking to transform manual workflows (CRM, support, analytics) with AI and automation. 📩 Contact me with your project details. I’ll honestly assess fit and outline an AI-driven solution before any commitment. Not a fit: Projects dominated by ultra-low budgets or impossible deadlines. Industries like gambling, adult content or fraud are out-of-scope. I also don’t do minute-by-minute hourly tracking; my focus is on delivering value, not punching clocks. less -
