๐Ÿ Every Python project I start โ€” before writing a single line of code โ€”
the automation is already in place.

Here's the stack I run on every project:

โšก uv โ€” environment and dependencies
๐Ÿ” Ruff โ€” lint and format in one pass
โœ… ty โ€” type checking at Rust speed
๐Ÿงช Pytest + coverage.py
๐Ÿ”’ pip-audit, Gitleaks, detect-secrets
๐Ÿ“Š vulture + radon โ€” dead code and complexity

One Justfile. One command. Every time.

๐Ÿ’ฌ What tools are in YOUR Python stack right now?

Is there something here you haven't tried yet โ€”
or a tool you think belongs on this list?

Drop it in the comments ๐Ÿ‘‡

๐Ÿš€ I just published something I've been working on for a while โ€” and I think it'll be useful if you're building with AI.

It's a curated, up-to-date reference for LLM tools covering the entire development stack โ€” from choosing a commercial API or open-source model, to deploying locally, fine-tuning, building agents, and evaluating your results in production.

What makes it different from other lists out there:

โœ… Updated to April 2026 โ€” current models, current pricing, current hardware requirements
โœ… Honest about what's deprecated โ€” Yi, Code Llama, DBRX, and DeepSeek Coder are all flagged as legacy so you don't waste time on abandoned projects
โœ… Includes recommended stacks โ€” not just a dump of tools, but opinionated combinations that work well together for common use cases
โœ… Built to stay current โ€” I'll keep updating it as the ecosystem evolves

Whether you're a developer just getting started with LLMs or an experienced engineer evaluating infrastructure options, there should be something useful in here.

If you find it useful, a โญ on GitHub helps more people discover it.
And if you know a tool that's missing or something that's out of date โ€” please tell me. That's exactly how this kind of resource gets better. ๐Ÿ™

๐Ÿ One Language. Every Career.

I want to share something that took me longer to appreciate
than it should have.

Python is not just a programming language.
It is the closest thing the tech industry has to a common tongue.

A data scientist in Paris, a cybersecurity analyst in Riyadh,
a backend engineer in Toronto, and an AI researcher in Tokyo
are all writing Python today. Not because they were told to.
Because the ecosystem they needed was already there.

Here is what makes Python genuinely different as a first language:

Most languages ask beginners to fight the language before they
can fight the problem. C asks you to manage memory. Java asks
you to understand classes before you understand functions.
Python gets out of your way and lets you think.

That is not a small thing. That is the whole game at the beginning.

**Where Python takes you โ€” and this list is not exhaustive:**

๐Ÿ“Š Data Science โ€” Pandas, NumPy, Matplotlib.
The entire data workflow was built here first.

๐Ÿค– Machine Learning & AI โ€” PyTorch, scikit-learn, Hugging Face.
If you want to train a model, you are writing Python.

๐Ÿ” Cybersecurity โ€” pen testers automate recon, analyse
malware, and build exploit scripts in Python.
It is in every serious security toolkit.

๐ŸŒ Web & Software Engineering โ€” Django and FastAPI handle
everything from a weekend project to a production API
serving millions of requests.

โš™๏ธ DevOps & Automation โ€” Ansible, AWS CDK, infrastructure
scripts. The automation layer of the cloud runs on Python.

๐Ÿ“ˆ Finance & Research โ€” quant analysts, academic researchers,
and scientific computing all reach for it when the problem
gets complex.

**This is why MIT, Stanford, Harvard, and CMU all teach it first.**

They are not making a branding decision.
They are making a pedagogical one.
Python lets students focus on learning to think computationally
rather than on the syntax rules that surround the thinking.

If you are at the beginning of your technical journey โ€”
or if you are switching fields and wondering where to invest
your learning hours โ€” Python is the answer that will not
require you to translate your skills when you reach your destination.

The card below puts all of this in one place.
Save it. Share it with someone who is still deciding.

๐Ÿ’ฌ What field are you building toward?
Drop it in the comments โ€” I read every one.

๐Ÿ“Š Here's what we covered in the Time Series Fundamentals course:

๐Ÿ“ Stationarity โ€” ADF & KPSS, differencing, decision rules
๐Ÿ“ˆ ACF & PACF โ€” reading plots, model order identification
๐Ÿ” ARIMA & SARIMA โ€” parameter selection, seasonal forecasting
๐Ÿ“‰ ETS Models โ€” Holt-Winters, additive vs multiplicative
๐Ÿ”ฎ Prophet โ€” trend, seasonality, holiday effects
๐Ÿ‡ฎ๐Ÿ‡ช Real Project โ€” Irish electricity demand, full pipeline

Theory you can explain.
Code you can run.
Real data. No shortcuts.

โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”

๐Ÿš€ And this is just the beginning.

The Advanced Time Series course is coming soon:

๐Ÿ“ก VAR & VECM โ€” multivariate forecasting
๐Ÿงฎ Kalman Filter & State-Space Models
๐Ÿ”ฌ Structural Models โ€” SVAR, GVAR, impulse response
๐Ÿค– Deep Learning for Time Series โ€” LSTMs & Transformers

Plus more practical courses in Python, ML, and AI Engineering.

๐Ÿš€ Here's what's coming to this page.

I'm building a full curriculum โ€” practical, deep, no fluff.

Here's what's on the roadmap:

๐Ÿ Python Programming โ€” Fundamentals & beyond
โ˜• Java Full Course โ€” From zero to production
๐Ÿฆ€ Rust Programming โ€” Systems & safety
๐Ÿค– ML Practical Course โ€” Supervised learning to deployment
๐Ÿ“ฆ And more on the way...

โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”

๐Ÿ‘‡ Two questions for you:

1. Which course are you most excited about?
2. What topic do YOU want me to cover that's not on this list?

Drop your answer in the comments โ€” I read every single one
and your feedback shapes what gets built next.

โ™ป๏ธ Share this if you know someone who needs to level up in 2026.

๐Ÿ”ฅ Ever wondered how ChatGPT actually thinks?

Or how AI systems like Gemini, Claude, and GPT-4 were built?

It all starts with one architecture โ€” Transformers.

I'm launching a complete, hands-on course to take you
from zero to building and understanding LLMs yourself.

โœ… Attention mechanisms โ€” decoded
โœ… BERT, GPT-4, T5 โ€” under the hood
โœ… The foundation for every agentic AI system you'll ever build

๐Ÿ“Œ Seats are LIMITED and registration opens very soon.

๐Ÿ‘‡ Drop a "INTERESTED" in the comments to get early access
and secure your spot before the public announcement.

โ™ป๏ธ Share this with someone who's serious about AI โ€”
you might just change their trajectory.

โš™๏ธ Two things that decide whether a model ships or stays in the lab:

๐Ÿ”น The format you save it in
๐Ÿ”น The strategy you use to make it run on the target device

Visual 1 โ€” PyTorch model serialization
state_dict, TorchScript, ONNX, and torch.export.
Four formats. Four different deployment contracts.

Visual 2 โ€” Quantization
Float32 to Int8.
4x smaller. 2โ€“4x faster at inference.
Three strategies. One decision based on what you have at deployment time.

๐Ÿ“Œ Save both. The gap between a trained model and a deployed model
is exactly where these two techniques live.
