What I’m working with

My current specialty is working with LLMs and AI agents. I use LangChain, LangGraph, LlamaIndex, etc. I also love analyzing data and producing beautiful reports using Quarto. You can also contact me if you need any assistance with databases, especially graph databases. I’ve been itching to put Gel DB into practice for a project.

I made a YouTube video about Cytoscape that got a lot of views and I would like to get back to making more videos. I’ve also been on some scientific publications.

You can learn more about me, read my resume, or find me on LinkedIn.
