Comment “data” for my intro to SQL course, perfect for complete newbies to build your first project in 30 min. Most common data interview question ⬇️ save this for later! One of the most common interview questions is this: What’s the difference between ROW_NUMBER, RANK, and DENSE_RANK? Most business problems only need ROW_NUMBER, but for some reason hiring managers are OBSESSED asking this one!! • ROW_NUMBER: sequential ranking, no duplicates, no skipped numbers • RANK: duplicates share the same rank, but numbers get skipped after ties • DENSE_RANK: duplicates share the same rank, no skipped numbers 🏷️ data analytics, data analytics project, data project

🚀 Stop chasing "better" models. Start building better features. Most Data Science students spend 90% of their time tuning hyperparameters. But here’s the truth: A simple model with great features will beat a complex model with bad features every single time. I put together this animation to break down the 7-Step Feature Engineering Workflow that actually moves the needle: 1️⃣ Raw Data: It’s always messy. Embrace the chaos. 2️⃣ Data Cleaning: Handle those NaNs before they break your logic. 3️⃣ Categorical Encoding: Turning text into numbers so the math can happen (One-Hot Encoding is your friend!). 4️⃣ Feature Scaling: Don’t let "Income" dominate "Age" just because the numbers are bigger. 5️⃣ Feature Creation: This is where the magic is. Combine variables (like Height + Weight = BMI) to give your model new insights. 6️⃣ Feature Selection: More isn’t always better. Drop the noise. 7️⃣ Model Ready: Clean, scaled, and optimized. Feature engineering isn't just a step in the pipeline—it's where the domain expertise meets the data. Students: Which of these steps do you find the most challenging? Let’s discuss in the comments! 👇 #DataScience #MachineLearning #FeatureEngineering #Python #AI

Know your customer. Who is this data for? Before I build any dataset, I ask one thing: Who’s going to use it? Because the “customer” determines everything: structure, complexity, even data types. Data for Analysts & Data Scientists → easy to query → no unnecessary complexity → minimal exotic types Data for Data Engineers → compact → nested structures are fine → optimization matters Data for ML models → depends on the model → feature structure > human readability Data for Clients / non-technical stakeholders → straightforward → clean & interpretable → easy to trust Same raw data. Very different design choices. Data modeling isn’t just technical work. It’s context work. Would you agree? #dataengineering #datamodeling #analyticsengineering #machinelearning #100daysofdataship

You don’t need Al! You need to start small! There’s no reason to jump straight to Al, LLMS, agents or RAG, 90% of the data in the market is tabular and requires simple but robust solutions. On top of that some people jump in without a plan or understanding what these skills are or what they do in the market. Learn Python basics and write clean code Practice in Google Colab or Jupyter Notebook Get comfortable with NumPy and Pandas Visualize with Seaborn Take Stanford’s free Machine Learning course Master core algorithms like Logistic Regression, SVMs, and Decision Trees. Practice with projects like Titanic or Wine Quality to learn the full workflow You won’t be building your portfolio in 3 months. Instead take that time to get comfortable with these tools, learn key skills and train on the most in-demand skills. Follow @crack_with_aj to master DIY data science on your own, become a builder, Al-powered and go from a learner to earner. I created a data science guide just for you, comment DATA and I’ll send it your way!

you’re not bad at SQL and you’re definitely not behind ☁️ most tutorials teach you what SQL queries do, not when you’d actually use them. That’s why it feels like you’re learning a lot but nothing is clicking (believe me I’ve been there!) in real data jobs, you won’t always be asked to just write specific queries. you’re asked to answer business questions and SQL is the tool you’ll use to get there. if you’re learning data skills and feeling stuck, comment “SQL” and I’ll point you to my resources that I created specifically for beginner data analysts 💻

Most Data Scientists spend 80% of their time on janitor work like cleaning data and brute-forcing hyperparameters. AutoGluon helps you by automating the search space so you can focus on the actual business problem. Here’s why this is a game-change: The “Time Limit” Strategy: You can literally tell AutoGluon, “Find me the best model possible in exactly 60 minutes.” It will budget its own training and stacking to ensure you have a result by your next meeting. Model Distillation: Big stacked ensembles are great for accuracy but can be slow in production. AutoGluon can “distill” that massive ensemble back into a single, fast model (like a small ResNet or MLP) that retains most of the accuracy but runs 10x faster. Multimodal Support: It’s not just for CSVs. It can fuse Image + Text + Tabular data into a single Multimodal-Predictor without you having to build complex multi-input architectures by hand. If you’re still manually grid-searching your way through a project, you’re leaving performance on the table. Comment “Repo” and I’ll DM you the link to the official GitHub so you can try it today. #machinelearning #ai #artificialintelligence #Python #algorithm
