📅 Day 27 – #Backend #DSA.🔧 Backend: Built NodeJS APIs, file ops, logging, modules, access control. 🔢 DSA: Practiced C++ OOPs—inher., polymorphism, exceptions, file handling, linked lists. Mixing both sides, learning daily. #100DaysOfCode #WebDev #Coding #JavaScript #CPlusPlus

📅 Day 50 on #LeetCode – got the badge!. It’s just showing up daily, solving problems bit by bit. No magic, no big leaps—just small steps, retries, and stubbornness. Still learning. Still messy. Still here. #100DaysOfCode #KeepGrinding #CodingJourney
