Your New Year Gift Is Here (Subscribers Only) 🎁
New Year, New Energy… and a Gift 🎁
Hey friends, Hossein here 👋
It’s been a while.
Between intense case work at a major consulting firm and a few life side quests, HosseiNotes had to pause for a bit. But heading into the new year, I wanted to restart this newsletter with fresh energy, and something genuinely useful for you.
During the break, I stepped back to rethink what value I can consistently create for you. I refined the concept, cleaned up the structure, and even refreshed the visual identity, new logo (😎), new look, new direction.
You’ll see more of that rolling out soon 👀
And to kick off this new chapter…
🎁 Here is your New Year gift: HosseinCodes!
Ladies and gentlemen… allow me to present your New Year gift: HosseinCodes!
Yes… I finally did it.
A secret vault.
A private code stash.
A “please-don’t-share-this-publicly” corner of the internet just for subscribers.
Starting today, every mini-series on HosseiNotes comes with its supporting code inside HosseinCodes, a private GitHub space where I put the good stuff.
(You know… the things I usually keep buried in my personal notes.)
👉 To get access, send me the GitHub email/username you want whitelisted
to notes@hossein.ai (I promise I won’t judge your GitHub username 😅)
Once you’re in, you’ll keep getting access to:
Code behind each mini-series
Useful prompt templates
Programmatic runners + utilities
Clean, practical and well-tested building blocks you can plug into your projects
Welcome to the inner circle 😎
🔧 First Drop in HosseinCodes:
AI Trip Advisor - prompts & runner
Repo: prompts-ai-trip-advisor
This repo contains all the code behind our first mini-series on hosseinotes - building a simple but surprisingly capable AI Trip Advisor.
Inside you’ll find:
Two prompts
prompts/prompt.md- dialog-style, copy/paste into any chatbot UIprompts/prompt_template.md- structured template for programmatic use
One runner
main.py- minimal Python script that calls OpenAI and prints JSON only (pretty-printed)
This is the exact setup I used to build and test the system.
Clean, small, and easy to learn from.
More prompts and more mini-series code will be added as we go.
🚀 What to Expect From HosseiNotes in 2026
✔ Bite-sized, practical notes
Small, focused ideas you can use immediately.
✔ Real examples + supporting code
Every mini-series will come with its working snippets.
✔ Useful prompts
Ones I actually use and have well-tested, not generic templates scraped from the internet.
✔ A steady rhythm
No fluff. No long theory dumps. Just actionable insights.
That’s the plan.
🤝 Thanks for sticking around
If you’re still reading this, you’re part of the earliest group - and I truly appreciate it.
This year, I’m committed to making HosseiNotes a place where you learn practical, powerful things that make you better at building with AI.
Next issue coming soon.
New logo, new direction, same spirit:
AI engineering without the PhD 😅
See you in the next note!
