Welcome to Bug Tales - a collection of debugging stories, mysterious bugs, and the journey to solve them.

Every developer has war stories about bugs that took days to find, edge cases that broke everything,  and those "impossible" issues that turned out to have the simplest solutions.

Here I share some of the most interesting bugs I've encountered, the investigation process,  and the lessons learned along the way.

### Featured Bug Tales
- **The Case of the Disappearing Data**: A race condition that only occurred on Tuesdays - **Memory Leak Mystery**: How a single forgotten event listener brought down production - **The Unicode Nightmare**: When emoji broke our entire search functionality - **Async Await Confusion**: The Promise that never resolved (and why)

*Coming soon: Interactive debugging challenges and more tales from the trenches!*

ANIMATED DYNAMIC QUOTE FOR GITHUB PROFILE README

Designed a Smark Mask - Corona, for the Hackathon event, which consisted of a Smart Mask that beeped whenever two people violated social distancing, which was connected using Bluetooth Technology, also stored the data in who came in contact with the person on the server-side. A Mobile application was designed, to view this data and general stats regarding Corona.



Stack: Arduino, C++, Bluetooth Technology, Spring Boot, React Native, MySQL

Smart Corona Mask

This project aimed at designing a Garbage Collection System using a Robot in the Indoors based on Indoor Positioning System using Internet of Things. A smart bin was deployed which would notify the Collector Robot to collect the garbage as and when it was filled.

A system consisting of a smart bin and an Autonomous Garbage Collecting Robot collects the garbage from the bin when the garbage threshold level is reached.
