Agents that actually act

I will automate your email. your WhatsApp, your Shopify customer's query reply Your client follow-ups. Agentic AI that reads real data, calls real tools, and solves the repetitive problems eating your day — instead of just answering questions in a chat window.

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

Three 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

CNN and Transformers for Disease Detection

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.

Selected work

AI systems & engineering research

Let's build something that has to work.

Open to freelance and contract work — agentic AI systems, biomechanical simulation, or both. If you can describe the problem, I can tell you honestly whether it's a good fit.
