Puzzle Games: Logic & Word Puzzles

Built a game using pygame library. Designed and implemented game characters and mechanics from scratch. Implemented some extra features like pause page, gradually increasing difficulty level.

Alien Attack

Detection of anomalies (port scan or denial of service attacks) using SpotLight algorithm. It
focuses on detecting anomalies in dynamic graphs in the stream. It uses K-random induced sub-graphs to calculate anomaly score. Around 20
sub-graphs suffice for thousands of nodes. 

Detecting Anomalies in Streaming Graphs

Developed a computer vision system that can automatically detect driver drowsiness in a real-time video
stream and then play an alarm if the driver appears to be drowsy.
- Detected facial marks using convex hull trick and checked Eye Aspect Ratio, yawning, head angle to determine the drowsiness.
- Also developed an ML model for the same.

Driver Drowsiness Detection

Implemented the research paper "Efficient Processing of Range Queries over Distributed Relational
Databases". Used Python and Postgres DB to setup distributed database. Optimized the suggested method using range based partitioning.

Efficient Processing of Range Queries

 Wrote a Python script to automate Facebook messaging using Selenium WebDriver.

FB-Message Bot

Web app to demonstrate process scheduling in OS. 
Algorithms implemented are - First Come First Serve (FCFS), Shortest Job First (SJF), Round Robin Scheduling (RR), Shortest Remaining Time First (SRTF), Priority Scheduling - Preemptive & Non-Preemptive.
All algorithms are implemented in JavaScript.

Process Scheduler

Developed a web application to solve the problem of mini-projects involved in academic courses. Project submission, review and evaluation can be done through the platform. Used Django for back-end and MySQL for database.
