Build AI Chatbots that answer your customers

Clients see 40% faster response times

Your customer sends a message the chatbot replies instantly, with the right answer. It runs on your Website, WhatsApp, email, and Shopify store around the clock.

Shopify Store Automation Demo

Who I am?

I hold a Master's in AI from NED University, and I specialized in: AI chatbots and automation for WhatsApp, email, and Shopify. If your customers are messaging you at all hours, I build the agent that handles it for you.

Every agent I build ships with human-approval gates, typed schemas, cost tracking, and full error handling. Automation that occasionally breaks is worse than no automation. I build for reliability, not demos.

What I build

Two areas of focus

SHEET 01

Agentic AI & Automation

Tool-calling agents that read inboxes, chat platforms, and storefronts, then act not chatbots that only answer FAQs. Built with LangGraph orchestration, LLM inference, and a human-review gate before anything ships to a customer.

SHEET 02

Disease Detection via Transformers

Classification and detection models for medical and biomechanical imaging trained, validated, and documented for a clinical or research audience, not left as a notebook demo.
