Isaac Flath
I build things and share what I learn.

“If I had to pick one individual to assist me in tackling an unknown data-related problem, large or small, it would be Isaac.”
What I Do
I build developer tools and retrieval systems. I write one post a week, always from a real project. I also teach courses and build products, but the writing is the center of everything here.
I care about the full loop: building something, figuring out what worked, and writing it up so other people can use it too.

“I'll read anything Isaac writes: it's high signal, makes me think, and helps me understand what's happening in AI.”

Three representative posts per domain.

“Impressive balance of simplicity, technical sophistication, and down-to-earth honesty.”
Raw to Draft
You already created the content. That demo you recorded. Those notes. The AI agent log. Now share it everywhere.
Plot Builders
Finish your novel. Most writers never do. You will. If you've got a story that's been living in your head rent-free for years, maybe it's time to finally write it.
Hamel Husain
ML Engineer, 25+ years of experience
“High signal on how to use AI effectively. He actually shows his work and builds things.”
Courses
Retrieval is active. AI-assisted coding is a prior course that is no longer running.
AI-Assisted Coding (Archived)
A systematized workflow for AI-assisted development. This course ran in 2025 and is no longer active, but the materials and testimonials capture the approach.
Learn RAG
Master Retrieval Augmented Generation from keyword search to multimodal search, chat interfaces to citation generation.

“I can now add features more easily, hunt down and fix bugs faster, and make my code more secure and reliable.”
Beyond Work
My primary hobby is dance. I used to teach ballroom dance full time, which is where I met my partner.

“Isaac and Eleanor are great people who lend their ears and try to help... The respect and love they bring feels so fresh.”
I write one post a week.
Every one comes from something I've done on a real project. AI tools, development approaches, how I actually build things. You're getting a curation of my taste, not takes on stuff I don't use.
