Modular AI chatbot platform
A series of chatbots, each a step further: from a basic prototype to one with memory, tools and a database behind it.
What makes a chatbot useful is memory and tools, not the model alone.
Owns Tesco’s national ordering engine, the system that decides what gets ordered, from where and for which depot. An engineer at EY before an MBA and product at Optum.
What Sunil wrote about the course after Cohort 08. These are real people with real portfolios, not marketing copy. Want to talk to Sunil? I’ll intro you.
I would not consider this a course. It was more about learning from someone who has gone very deep in this area.
This program gave me a direction on how to start thinking about the use cases and the implications around them. The hands-on experiments helped me understand the basics of each aspect and forced me to think through the complexity.
Would definitely recommend it if you want to start building and experimenting on your own rather than just reading the concepts.

Turns podcast episodes into vector embeddings, so you can ask a question and get the answer from what was actually said.
How retrieval keeps an answer grounded in real content.
One agent loop that searches and reads the web, remembers you between sessions, runs a job search from your resume and answers the phone, with chat and voice sharing one memory.
The assistant grows by registering tools, not by adding branches.
Four years as an engineer at EY, an MBA, then product at Optum and Tesco: what carried over, and what had to be unlearned.
Leading inventory work for Tesco’s fresh and ambient distribution centres: the biggest issues were in the plain current state, not in the algorithms.
Moving Tesco’s national ordering engine from a legacy monolith to an API-first architecture while the business kept running on it.
