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 -

We build the product and the intelligence inside it, rather than bolting a chatbot onto someone else's website. WHAT WE BUILD - AI agents and assistants that call your real APIs, with tool use, memory and approval gates - RAG search over your own documents, catalogs and policies, so answers cite a source instead of guessing - Voice AI: realtime phone and browser agents, sub-second, interruption handled - The full-stack product around it: Next.js, React, Node, Python, WordPress and Shopify - Mobile apps in Flutter, one codebase for iOS and Android - The plumbing that makes it real: API integrations, scraping, dashboards, AWS, Docker and CI/CD HOW WE WORK You talk to the people writing the code, not an account manager. Scope is agreed in writing before we start, so the price does not move unless you change the brief. You see working software early instead of status updates. Code, credentials and documentation are handed over at the end. The project is yours. WHAT WE HAVE SHIPPED A multilingual voice platform running 500,000+ commands a month at 99.3% uptime. A bilingual Next.js product with retrieval search, whose client hired us straight back for the MVP APIs. AI calling systems tuned in production. Shopify catalog and bundle automation. Stripe checkouts, Flutter apps, Tableau dashboards, AWS deployments, and a native C++ audio plugin when the job called for one. Tell us what you are trying to build and what has to be true for it to work. We will tell you what it takes, honestly, including when the answer is that you do not need AI for it. less -
