Projects
Attribute Inference in Social Networks using Sorensen–Dice Similarity & RwR
- Designed and implemented a graph-based attribute inference engine using Sorensen–Dice Similarity and Random Walk with Restart (RwR) to predict hidden user attributes in social networks.
- Validated on a real-world Facebook dataset (4,000+ users, 88,000+ connections), achieving up to 40% improvement in prediction precision over baseline methods.
- Published findings at IEEE SMARTGENCON 2025 — demonstrating research-grade software design and experimental rigor.
Pet-Store Management System — CRUD E-commerce Backend
- Developed a modular, service-oriented e-commerce backend supporting full CRUD operations for product listings, orders, and user management.
- Designed normalised relational schemas and optimised complex SQL queries, reducing query execution time by ~30% through indexing strategies.
- Implemented concurrency-safe DB transactions and applied OOP principles for clean, reusable code modules.
