Built Smart Contact Manager ๐ป from a real-life problem!
During exams in Amritsar, I forgot my friendโs number ๐ โ so I made a web app to store & manage contacts safely, anytime, anywhere.
๐ก Auto-save feature coming soon!

Spring Security Integration Done โ
Faced issues with authentication flow, 405 errors & logout setup โ but finally got everything working!
Each bug made me understand Spring Security much better

40% done with Smart Contact Manager! Late-night coding, countless tiny bugs, and some validation nightmares, but every fix teaches me something new and keeps me motivated ๐๐ป

Every project starts with an idea โ today mine takes shape: an AI-Based Fitness Tracker ๐ ๏ธ
Sketched the system design:
๐น API Gateway
๐น Kafka (async comms)
๐น Keycloak (auth)
๐น Eureka + Config Server
๐น DBs for persistence
๐น AI via Gemini API

๐ Attended a hands-on Machine Learning workshop today!
๐น Trained a Teachable Machine model to detect face orientation (front, left, right) โ useful for tracking student attentiveness! ๐ฏ
๐น Explored AI in image processing โ facial expressions, sign gestures, object detection & quality inspection.
๐น Built a hand gesture recognition model using Landing AI โ dataset labeling, training & deployment
๐น Ran real-time AI inference on Google Colab with Landing AIโs API.
๐ Just started my Cloud Computing journey with AWS!
Today, I learned:
โ๏ธ What cloud computing is
๐น Types of cloud models (Public, Private, Hybrid, Multi-Cloud)
โ Why cloud is the future (scalability, cost-saving, security)
๐ Cloud service models (IaaS, PaaS, SaaS)

Sorting also works, but it's O(n log n) time complexity. Then, I found a much simpler and faster way: Boyer-Moore Voting Algorithm. It works in O(n) time and O(1) space, making it the best approach for this problem.
Today, I faced an issue while solving a LeetCode problem... ๐ค
The problem was simple: Find the majority elementโthe number that appears more than n/2 times in an array.
At first, I thought of using a hashmap to count occurrences, but that takes extra space (O(n)).
