Didn't get to code as much as I wanted, but still squeezed in some solid learning: ✅ Express.js: Writing to MongoDB ✅ ML: XGBoost pipelines & hyperparameter tuning ✅ Java: String methods (still fighting local vs instance variables tbh 😅)

Finished the streak by optimizing a 2D Matrix Binary Search on LeetCode. Learned a genius math trick (mid // cols, mid % cols) to logically treat a 2D grid like a flat 1D array for a single, ultra-fast O(log N) search! 🧠 Massive overview dropping tomorrow. Stay tuned! 🔥

Day 90 of #90DaysOfCode 🚀 We officially hit Day 90! 🎉 But the grand reflection post is coming tomorrow because today was packed with heavy uni classes and I'm running on fumes.

Day 89 of #90DaysOfCode 🚀 Non-stop lectures, terrible power supply, and completely dead devices. Squeezed out enough battery to solve LeetCode "Divide Two Integers" (Medium). Since *, /, and % are forbidden, I used bitwise shifts (<<) to perform exponential subtraction.

After hours of debugging, I had to completely downgrade to Prisma 6 just to get my DB seed files to work properly. Dependency management is the real final boss of backend development! 😅 Tomorrow: fixing the rest of the DB access points. Only 2 days left! 🔥 #NodeJS #Prisma

Day 88 of #90DaysOfCode 🚀 Spent the entire day fighting database demons! 👿 Tried to run tests on our backend project, and everything went completely haywire.

Day 86 of #90DaysOfCode 🚀 Dove into the heart of Java today: Object-Oriented Programming! ☕ Mastered the core building blocks: 🏗️ Classes, Objects, Fields, & Methods 🔒 Access Modifiers (public, private, protected) ⚡ The static keyword

Day 85 of #90DaysOfCode 🚀 Completed the "Regression with XGBoost" module on DataCamp today! 🏡📈 Dived deep into the mechanics: 🧠 Decision Tree vs. Linear Base Learners 📉 Applying Regularization to prevent overfitting
