Making some interesting projects in different languages.

About

I am a Computer Science and Engineering student dedicated to developing practical, performance-driven solutions. My core interests are rooted in software development and the creation of tools that enhance productivity, including expense tracking systems and interactive web applications. I am deeply engaged in leveraging modern technologies, with a strong emphasis on clean, intuitive, and effective UI/UX design, while consistently honing my problem-solving skills through mathematics and programming. My goal is to design and deliver efficient, user-focused software that streamlines and optimizes everyday tasks.

Projects

01

Expense Tracker Application

A productivity-focused application designed to help users efficiently manage and monitor their daily expenses.

UI/UXProductivityPerformance
  • Developed a system to record, categorize, and analyze financial transactions
  • Implemented user-friendly interfaces for seamless data entry and tracking
  • Focused on performance optimization and clean UI/UX for better usability
  • Designed to improve financial awareness and decision-making
02

Random Graph Generation & Handshaking Theorem Verification

A computational project that generates random undirected graphs and verifies a fundamental principle of graph theory, the Handshaking Theorem.

CGraph TheoryAlgorithmMemory Management
  • Developed a C-based program to construct random undirected graphs using an adjacency matrix representation
  • Implemented dynamic memory allocation to efficiently handle large graph sizes (e.g., 1000+ vertices)
  • Generated edges probabilistically to simulate random graph structures
  • Calculated vertex degrees and total edge count to validate the theorem (sum of degrees = 2 x number of edges)
  • Integrated execution time measurement using system clock functions to analyze computational performance
  • Ensured proper memory management through allocation and deallocation of dynamic data structures
03

Ceremony Seat Management System

A structured console-based application developed to manage seating arrangements efficiently for events and ceremonies through systematic booking and data handling.

CData StructuresFile HandlingSystem Simulation
  • Designed and implemented a seat management system using structured programming in C with a 2D array-based layout
  • Developed functionalities for seat booking, cancellation, and updating guest information (name and phone number)
  • Implemented dynamic seat allocation with validation to prevent duplicate bookings and invalid inputs
  • Integrated file handling mechanisms to persist and retrieve seating data using binary file operations
  • Created a real-time visual representation of seating arrangements for improved usability and clarity
  • Applied modular logic and input validation techniques to ensure system reliability and data integrity
