The 7 websites that separate good analysts from great ones. Not Kaggle. Not LeetCode. Not Tableau Public. The ones no one talks about but every senior analyst quietly uses. Scroll this carousel ➡️ Here's what's inside: → data.world: real, messy, enterprise grade datasets. If you've only touched clean CSVs, this changes everything. → Google BigQuery Public Datasets : this isn't practice data. This is production-scale data. Billions of rows. One project here beats 10 Kaggle notebooks. → dbt Docs : most people scroll past "DBT." Huge mistake. Reading this makes your SQL cleaner overnight. → Mode SQL Tutorial: this is where SQL stops being academic. Business-first problems. Real stakeholders. Real dashboards. → Our World in Data : everyone visits it. Very few use it correctly. Download the raw data. Recreate charts from scratch. That's analytical thinking. → GitHub Issues :not repos. Issues. See how real data problems are discussed, debated, and broken down by actual teams. → SEC EDGAR :want to sound senior fast? Learn this. Real financial data at scale. Insane project ideas no one else is doing. Most people learn tools. Very few learn how data is actually used. These websites won't make you look smart. They'll make you hireable. Save this. Come back when your learning feels stuck.

🚀 Breaking into Data Engineering — My Thought Process Lately, I’ve been going through a lot of posts about how to enter different tech domains — Data Science, Data Analysis, Software Engineering, and more. After reading, observing, and trying to connect the dots, one thing became very clear to me: 👉 Every strong Data Engineering journey starts with SQL. This isn’t just a random choice — it’s something I’ve understood by analyzing how professionals actually work with data in real-world scenarios. So I thought — why not share my understanding here, and also learn from people who’ve already walked this path? 💡 Here’s how I believe one should start with SQL to build a solid foundation: 🔹 Start with the basics Understanding SELECT, WHERE, GROUP BY, ORDER BY — the building blocks of any query 🔹 Learn Joins deeply INNER, LEFT, RIGHT joins — because real-world data is never in a single table 🔹 Work on Aggregations COUNT, SUM, AVG — converting raw data into meaningful insights 🔹 Practice Subqueries & CTEs To write structured, readable, and scalable queries 🔹 Explore Window Functions ROW_NUMBER(), RANK(), DENSE_RANK() — this is where SQL starts getting powerful 🔹 Focus on Performance Basic indexing and writing optimized queries 🔹 Apply in Real Scenarios Not just syntax — but solving actual business problems ✨ From what I’ve understood so far, SQL is not just a skill — it’s the foundation of how you think about data. This is my starting point into Data Engineering, and I’m excited to keep building on top of it. 🤝 I’d genuinely love to know from experienced folks: - Am I thinking in the right direction? - What would you suggest adding or changing at this stage? - Any resources or habits that helped you early in your journey? Looking forward to learning, improving, and growing with this amazing community here on LinkedIn. #DataEngineering #SQL #LearningInPublic #CareerGrowth #TechJourney #DataCommunity #Azure #it #DataAnalyst

🚀 From Raw Data to Real Insights — My End-to-End Customer Churn Analysis Project I recently built a complete data analytics project where I went beyond dashboards and focused on solving a real business problem: 👉 Why are customers leaving? Here’s how I approached it step by step 👇 🔹 SQL (PostgreSQL) — Data Foundation • Imported raw churn dataset into PostgreSQL • Cleaned messy data (handled NULLs, fixed data types like TotalCharges) • Created a structured churn_clean table • Performed feature engineering (tenure groups, charge categories) 🔹 Python — Data Processing & Machine Learning • Connected Python with PostgreSQL using psycopg2 • Loaded clean data into Pandas • Performed preprocessing (encoding categorical variables) • Built a Random Forest model to predict churn • Achieved ~80% accuracy in identifying high-risk customers 🔹 Power BI — Business Intelligence Dashboard • Designed an executive dashboard with: ✔ KPIs (Total Customers, Churn Rate %, Avg Charges) ✔ Churn analysis by tenure group ✔ Interactive filters (Gender, Contract, Payment Method) • Highlighted key insights: • New customers have higher churn • Month-to-month contracts drive churn • Electronic payment users show higher risk 💡 Key Learning: Data is not just about numbers — it’s about telling a story that drives decisions. This project helped me understand how to build a complete pipeline: ➡ Data Cleaning → Analysis → Prediction → Visualization 📊 Tools Used: SQL | Python | Power BI | Machine Learning #DataAnalytics #PowerBI #SQL #Python #MachineLearning #DataAnalyst

Most people think Data Analytics is about tools… it’s actually about thinking. This visual maps 64 essential Data Analyst concepts—and it reveals something important: It’s not just SQL, Excel, or Power BI. It’s a blend of skills across multiple domains. Here’s how it all connects:  🞄 Data Handling → SQL joins, ETL/ELT, data cleaning  🞄 Statistics & Experimentation → hypothesis testing, A/B testing, distributions  🞄 Business Thinking → KPIs, funnel analysis, segmentation  🞄 Technical Tools → Python (Pandas, NumPy), dashboards, visualization  🞄 Advanced Concepts → causal inference, feature engineering, forecasting 💡 Key Insight: Great analysts aren’t defined by the tools they use… they’re defined by how well they connect data to decisions. 🔧 Practical takeaway: If you’re learning or growing in this field, don’t try to master everything at once. Instead, focus on building in layers:  🞄 Start with SQL + Excel fundamentals  🞄 Add statistics & business understanding  🞄 Then move to Python, dashboards & advanced analytics 📊 Real-world truth: A simple analysis with the right business context beats a complex model with no clear impact. Strong analysts don’t just analyze data… they tell stories, drive decisions, and create impact. #DataAnalytics #DataScience #SQL #BusinessIntelligence #CareerGrowth #AnalyticsSkills #DataLearning

🚫 Stop acting like a data gatekeeper. Most teams are stuck in this loop: Business asks a question - Analyst spends hours cleaning + querying - Insight arrives too late - Decision already made I’ve worked in data operations - I’ve seen this firsthand. So I’m building SmartOps to break that cycle. Week 2 of 8 - Architecture "Top 5 cities by revenue last month" ↓ Gemini ↓ Google BigQuery (SQL generated) ↓ Answer in seconds ↓ Power BI 100,650 rows · 7 tables · Star schema Views are structured so the model follows predefined logic - not guesswork. The hard truth nobody talks about You can’t plug an LLM into raw tables and expect clean answers. If your data model is messy - your insights will be too. AI is the visible layer. Data modeling is the real work. What this is aiming to replace From: “Can you send that report by EOD?” To: “Top 5 cities by revenue last month” Answer in seconds Build progress ████████░░░░░░░░ Week 2 of 8 Week 2 of 8: Full code · SQL queries · PM artifacts (Project Charter · Stakeholder Map · Risk Register · UAT Test Cases) Because a system without governance is just a script. 🔗 https://lnkd.in/gU8MEBA6 #DataOps #BusinessIntelligence #SQL #BigQuery #PowerBI #AI #DataEngineering #BusinessAnalyst

✨ Feeling excited about how much clarity comes with consistent learning. And here’s something powerful I realized recently 👇 👉 The difference between an average Data Engineer and a high-paid one… is NOT tools. It’s problem-solving ability. 🚀 I’ve been going through real interview questions from top companies, and patterns are clear: They don’t ask: ❌ “What is SQL?” ❌ “What is PySpark?” They ask: 💥 “How will you calculate rolling metrics?” 💥 “How do you handle missing or dirty data?” 💥 “How do you optimize a slow pipeline?” 💥 “How do you design for scale?” 💡 That’s when it clicked: Learning syntax is easy. Thinking like an engineer is rare. 📌 If you’re preparing for Data Engineering roles, focus on: ✅ Window functions & analytical SQL ✅ Real-world scenarios (not textbook examples) ✅ Data cleaning & edge cases ✅ Performance & optimization mindset ✅ Explaining your approach clearly 🔥 Golden rule: Don’t just practice queries. Practice thinking behind the query. 🌱 To anyone learning silently: You’re not behind. You’re building depth — and that compounds. 🤝 Let’s connect and grow together #DataEngineering #SQL #PySpark #InterviewPreparation #CareerGrowth #LearningInPublic #BigData #TechCareers

If I were starting Data Analytics in 2026, this would be my roadmap. Not random tutorials. Not scattered YouTube videos. A clear, structured path that actually gets you job-ready. Here’s how I’d do it: ✅ Start with the foundation Understand what a Data Analyst really does: problem-solving, storytelling and decision-making, not just tools. ✅ Light intro to statistics (very early) Mean, median, distributions What “variance” actually means with basic idea of data types. ✅ Master Excel Build strong fundamentals: Formulas (VLOOKUP, XLOOKUP, INDEX-MATCH, PivotTables, Data validation, Power Query, Dashboards (This could land you your first role if done well) ✅ Learn SQL like your career depends on it (because it does) Select, Where, Group By, Joins, aggregations, and performance optimization. ✅ Pick a BI tool (Power BI or Tableau) Dashboards, DAX/calculations, Data Modelling and storytelling for stakeholders. ✅ Leverage AI tools Use AI for SQL queries, insights, and faster workflows. Not as a crutch, but as a multiplier. ✅ Add Python 🐍 to your toolkit Focus on Pandas, NumPy, and real data cleaning + analysis workflows. ✅ Master storytelling frameworks. Insights are useless if decision-makers don’t understand them. ✅ Build a strong portfolio 3–5 solid projects is better than 20 half-finished ones. ✅ Understand cloud basics BigQuery, Snowflake, or AWS learn how data lives at scale. ✅ Get familiar with ETL pipelines dbt, Airflow, or even no-code tools and know how data flows. ✅ Practice real-world problems Kaggle, Hackathon, case studies, SQL challenges — this is where you grow. 🎯 The truth? Data analytics is no longer just about tools. It’s about thinking, communicating and solving real business problems. If you're starting in 2026, don’t just learn. build like you're already on the job. Happy New Month of May 🎉🍾 #dataanalystroadmap #dataanalyts
