Here are 12 skills that you wanna add to your Data Science / Machine Learning resume.

The first 6 are foundational and important. The other 6 are in crazy high demand, harder to build, and will set you apart.

🧵👇
The industry is relatively young so we are still figuring out titles and requirements, but certain skills are already surfacing as fundamental.

Here I compiled twelve of them.

They aren't all required. They just represent a good blueprint for you to focus on.

👇
1⃣ Notions of Probabilities and Statistics — You need at least enough to understand how some algorithms work and how to interpret their results.

2⃣ Data Management — Capturing, querying, storing, and transferring data. SQL is a very important skill here.

👇
3⃣ Data Wrangling — Preparing, cleaning, transforming the data for further analysis. This is one of the most important skills to build.

4⃣ Data Visualization — Usually an underrated skill. Your data is telling a story, and it's your job to present it to the world.

👇
5⃣ Programming — It's imperative that you know enough to draw insights from data using your language of choice.

6⃣ Machine Learning Algorithms — Understanding existing algorithms, and having the capability to apply them and interpret their results is key.

👇
Most people check these six skills.

But you aren't most, so here you have a list with the other six.

These are sexier but harder to build. These will set your resume apart.

👇
1⃣ Deep Learning — A subset of Machine Learning methods based on Neural Networks.

2⃣ Computer Vision and Natural Language Processing — These are probably the two hottest areas in the industry right now. They are about extracting meaning from images, videos, and text.

👇
3⃣ TensorFlow, Keras, PyTorch — These are the most popular libraries to build Deep Learning applications.

4⃣ Cloud Computing — Today, there's no Machine Learning without having access to the resources and services provided by the Cloud.

👇
5⃣ Big Data — The ability to deal with large and complex data sets. Tools like Hadoop and BigQuery are examples here.

6⃣ DevOps / MLOps — These skills are centered around the ability to build and manage machine learning pipelines and workflows.

👇
It's really difficult to acquire all of these skills and be good at every single one of them.

But you don't need that.

Instead, focus on the basics and expand your capabilities into areas that will increase your value.

AI is changing everything. Full stop.

If you still don't get it, watch this.

Look at the attached video. A company using this tool will execute 100x faster than everyone else. There's simply no match for how fast AI can transform what you do.
I'm working here with @PromptQL. They will help you build a reasoning AI that is specialized to your business.

This makes an ocean of difference:

• Connect to all of your data
• Build a massive knowledge graph
• Incorporate your unique know-how
• Learn over time
The learning part is the thing that blew my mind:

You can teach the system how to interpret your data and how you prefer things to be done.

This knowledge can be reviewed, edited, and deployed so everyone at your company starts using the new version of the model.

Here is how you can test your applications using an LLM:

We call this "LLM as a Judge", and it's much easier to implement than most people think.

Here is how to do it:

(LLM-as-a-judge is one of the topics I teach in my cohort. The next iteration starts in August. You can join at .)

2/11ml.school
We want to use an LLM to test the quality of responses from an application.

There are 3 scenarios:

1. Choose the best of two responses
2. Assess specific qualities of a response
3. Evaluate the response based on additional context

Bye-bye, virtual assistants! Here is the most useful agent of 2025.

An agent with access to your Gmail, Calendar, and Drive, and the ability to do things for you is pretty mind-blowing.

I asked it to read my emails and reply to every cold outreach message.

My mind is blown!
AI Secretary and the folks @genspark_ai will start printing money!

You can try this out here:

Check their announcement video and you'll see some of the crazy things it can do for you. genspark.ai
The first obvious way I've been using AI Secretary:

100x better email search.

For example, I just asked it to "show me the last 3 emails asking for an invoice for the Machine Learning School cohort."

I also asked it to label every "email containing feedback about the cohort."

You can now have a literal army of coding interns working for you while you sleep!

Remote Agent is now generally available. This is how we all get to experience what AI is really about.

Here is what you need to know:
Remote Agent is a coding agent based on @augmentcode. They were gracious enough to partner with me on this post.

Remote Agent:

• Runs in the cloud
• Works autonomously
• Can handle small tasks from your backlog

Here is a link to try it out: fnf.dev/4jobOrw
If you have a list of things you've always wanted to solve, let an agent do them:

• Refactor code and ensure tests still run
• Find and fix bugs
• Close open tickets from your backlog
• Update documentation
• Write tests for untested code

Knowledge graphs are infinitely better than vector search for building the memory of AI agents.

With five lines of code, you can build a knowledge graph with your data.

When you see the results, you'll never go back to vector-mediocrity-land.

Here is a quick video:
Cognee is open-source and outperforms any basic vector search approach in terms of retrieval relevance.

• Easy to use
• Reduces hallucinations (by a ton!)
• Open-source

Here is a link to the repository: github.com/topoteretes/co…Image
Here is the paper explaining how Cognee works and achieves these results:

Cursor, WindSurf, and Copilot suck with Jupyter notebooks. They are great when you are writing regular code, but notebooks are a different monster.

Vincent is an extension fine-tuned to work with notebooks.

10x better than the other tools!

Here is a quick video:
You can try Vincent for free. Here is a link to the extension:



It works with any of the VSCode forks, including Cursor and Windsurf. The free plan will give you enough to test it out.marketplace.visualstudio.com/items?itemName…
The extension will feel familiar to you:

• You can use it with any of the major models (GPT-X, Gemini, Claude)
• It has an option to Chat and Edit with the model
• It has an Agent mode to make changes to the notebook autonomously

But the killer feature is the Report View.
