Hassan A.

Expert Vetted Developer

I build conversational AI systems that actually ship, scale, and hold up in production, not demos that break under real traffic.

With over a decade in the industry including the last 3+ years focused on conversational AI, I have designed and deployed chatbots and voice assistants that handle millions of messages for startups and enterprise teams across the US, helping them cut support costs, automate lead capture, and run 24/7 customer interactions without adding headcount.

What I bring to your project:

• Conversational AI & LLM Engineering Production bots with Rasa, Dialogflow, and LangChain. RAG pipelines, intent and entity design, context handling, multi-turn flows, and LLM integrations (OpenAI, Anthropic, open-source models) wired into real business logic, not just a chat window.
• Backend & APIs High-performance services in Python with FastAPI. Real-time messaging over WebSockets, Redis for caching, queues, and session state, plus Twilio for SMS, WhatsApp, and voice channels.
• DevOps & Scale I ship and own the full pipeline: Docker, Kubernetes, CI/CD with GitHub Actions and Jenkins, deployed on AWS and GCP. Your bot stays fast, monitored, and online as usage grows.

Why clients keep working with me:

• Clear communication and predictable delivery. You always know status.
• I think about cost, latency, and maintenance, not just "does it work today."
• Clean, documented, handoff-ready code your team can build on.

If you need a conversational AI product or a Python backend built right the first time, send me a message with what you are trying to achieve. I will tell you honestly how I would approach it and what it takes.

Available for both fixed-scope projects and ongoing engagements.
