Recruiters don’t want to see more certificates—they want proof you can solve real-world problems. That’s where the right projects come in. Not toy datasets, but projects that demonstrate storytelling, problem-solving, and impact.

Here are 4 killer projects that’ll make your portfolio stand out 👇

🔹 1. Exploratory Data Analysis (EDA) on Real-World Dataset

Pick a messy dataset from Kaggle or public sources. Show your thought process.

✅ Clean data using Pandas
✅ Visualize trends with Seaborn/Matplotlib
✅ Share actionable insights with graphs and markdown

Bonus: Turn it into a Jupyter Notebook with detailed storytelling

🔹 2. Predictive Modeling with ML

Solve a real problem using machine learning. For example:

✅ Predict customer churn using Logistic Regression
✅ Predict housing prices with Random Forest or XGBoost
✅ Use scikit-learn for training + evaluation

Bonus: Add SHAP or feature importance to explain predictions

🔹 3. SQL-Powered Business Dashboard

Use real sales or ecommerce data to build a dashboard.

✅ Write complex SQL queries for KPIs
✅ Visualize with Power BI or Tableau
✅ Show trends: Revenue by Region, Product Performance, etc.

Bonus: Add filters & slicers to make it interactive

🔹 4. End-to-End Data Science Pipeline Project

Build a complete pipeline from scratch.

✅ Collect data via web scraping (e.g., IMDb, LinkedIn Jobs)
✅ Clean + Analyze + Model + Deploy
✅ Deploy with Streamlit/Flask + GitHub + Render

Bonus: Add a blog post or LinkedIn write-up explaining your approach

🎯 One solid project > 10 certificates.

Make it visible. Make it valuable. Share it confidently.

♾️ New Microsoft cloud updates support Indonesia’s long-term AI goals

✏️ Indonesia’s push into AI-led growth is gaining momentum as more local organisations look for ways to build their own applications, update their systems, and strengthen data oversight.

✏️ The country now has broader access to cloud and AI tools after Microsoft expanded the services available in the Indonesia Central cloud region, which first went live six months ago.

✏️ The expansion gives businesses, public bodies, and developers more options to run AI workloads inside the country instead of overseas data centres.
