Crash course on 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 for ML Engineers
Hands-on in 9 steps ↓ Kubernetes is one of the hard skills you nonstop find in job descriptions for ML engineers.

Yet, it is one of the tools most ML engineers are scared of.

Let me help you be less scared of Kubernetes, by deploying your first Python app.

Because ML models are not enough in real-world ML projects.
Until you don't put them to work, by building a

ML Project Idea 💡

Let's predict air quality in Poland 💨🇵🇱↓ In this repository, you can find the complete source code of an ML app that

→ predicts air quality (as measured by the PM10 metric) 💨
→ in Poland 🇵🇱
→ for the next 7️⃣ days

ML Project Idea 💡

Let's predict taxi demand in NYC in the next 60 minutes 🚕↓ Business problem 💼

Let's create a predictive model to forecast the number of taxi rides that will happen in Manhattan (New York City)

- in the next hour
- for each taxi zone (e.g. Zone 113 "Lower Manhattan)

Let's do it in 6 steps ↓

Are you a data scientist using CSV files to store your data?

What if I told you there is a better way?

Can you imagine a

-> lighter 🦋
-> faster 🏎️
-> cheaper 💸

file format to save your datasets?

Read this thread so you don't need to imagine anymore 👇🏾 Do not get me wrong. I love CSVs.

You can open them with any text editor, inspect them and share them with others.

They have become the standard file format for datasets in the AI/ML community.

However, they have a little problem...

3 years ago I struggled to build ML products.

Then I discovered this ↓ Unless you are a researcher in academia, and your goal is to publish a paper, you cannot just focus on the ML model you wanna train.

You need to think further down the line and think of the business problem you are trying to solve.

This is the "product-first" mindset.

Let's design an ML system to predict crypto prices, step-by-step ↓🧵 The problem

We want to build a real-time API that serves in real-time short-term predictions on crypto prices.

For example
To predict the price of Ethereum (ETH) in the next 10 seconds.

One skill every ML engineer has to master ↓ 𝗠𝗟 𝗦𝘆𝘀𝘁𝗲𝗺 𝗱𝗲𝘀𝗶𝗴𝗻

Yes. And do you know why?

Because good ML system design hasn't changed at all in the last 5 years.

And it won't.

Every aspiring data scientist I talk to is overwhelmed by the colossal amount of online courses to choose from 🤯

My solution to this problem ↓ Learning is about connecting the dots.

However, it feels like there are too many dots to connect when learning data science.

Too many courses...
Too many blog posts...
Too many technologies...

Solution: You need to change the way you learn.

Time-series are used everywhere

→ At Uber to optimize fleet efficiency
→ At Amazon to forecast inventory levels
→ At every hedge fund to project asset prices.

Still, there is a lack of ML engineers who can build real-world time-series products.

So here is your chance ↓ Let's build a *complete* ML service that forecasts taxi rides in NYC, similar to what Uber does to forecast demand.

The 3 ingredients we need are;

- a dataset
- a Python library to build a good predictive model
- a deployment strategy

For example ↓

3 years ago I struggled to land my first freelance ML engineering contract.

Then I discovered this ↓ Building one professional real-world ML project is the best way to stand out from the crowd, and land an ML job.

Here is what I did, 𝘀𝘁𝗲𝗽-𝗯𝘆-𝘀𝘁𝗲𝗽 👩‍💻👨🏽‍💻↓

Most of my ML model prototypes never reached production 😵‍💫

Until I changed my mindset 🧠↓↓↓ 🔬 Model-first mindset

A model-first mindset is what Kaggle competitions and most online courses are about.

Your ONLY focus is to build the best possible mapping between a set of input features, and a target metric

And in real-world ML this is often not the best approach...

Let’s say you work as an ML engineer at a fintech startup, whose flagship product is a mobile app for online payments.

A critical problem you need to tackle from day 0 is the automatic detection of fraudulent transactions.

Because Large Language Models alone are not enough to accurately answer complex tasks that require
