🚀 Flagship Engineering (Production & Architecture)

These projects represent end-to-end system design, from memory management to cloud deployment.

Project Architecture & Tech Stack Engineering Impact
Thirty
Distributed Geospatial Framework		 Flutter Firebase CMake Engineered a location-bound attendance protocol using dynamic QR tokenization and geofencing. Implemented cryptographic verification for immutable audit logs.
C V-Table Demo
Polymorphic Runtime Engine		 C Memory Low Level A manual implementation of C++ Virtual Tables in pure C. Demonstrates deep understanding of ABI layout, function pointers, and dynamic dispatch mechanisms at the compiler level.
IMS
Enterprise Resource Planning		 Python Flask MySQL Full-stack Insurance Management System. Features rigorous ACID compliance, Role-Based Access Control (RBAC), and optimized CRUD operations for high-volume transaction handling.

🧠 Computational Logic & Optimization (DSA)

A structured approach to solving NP-Hard problems and optimizing Space-Time complexity.

Repository Focus Area Key Concepts Applied
leetcode-patterns Algorithm Design 150+ Solutions focusing on Sliding Window, DP, and Graph Topology. Includes $T(n)$ analysis and memory optimization notes.
data-structures-fundamentals ADT Implementation Raw C implementations of Hash Tables, Binary Trees, and Graphs. Includes Dijkstra's Algorithm and Stack-based expression parsing.
searching-sorting Performance Tuning Comparative analysis of $O(N^2)$ vs $O(N \log N)$ sorting algorithms (Quick/Merge) and Binary Search space reduction techniques.
