Early projects and experiments from my student years
Hyperledger Fabric Research
Research project exploring Hyperledger Fabric for secure, interoperable healthcare record sharing. Built a proof-of-concept that puts patients at the center of the system, enabling trustable EHR data exchange across providers.
Used by 1000+ university students
A visual simulator for CPU scheduling algorithms (FCFS, SJF, Round Robin, Priority) that enables students to understand process scheduling, resource utilization, and real-time performance characteristics. Adopted by professors for coursework.
Smartphone sensor-based detection
A fall detection system using smartphone accelerometer and gyroscope sensors for human activity recognition, achieving 0.77 sensitivity and specificity. Designed for elderly care applications.
IoT + Arduino safety system
Detects vehicle accidents using Arduino sensors and automatically contacts the nearest ambulance via GSM module. Includes a Django web application for emergency dispatch coordination.
Multi-node IaaS infrastructure
Documented and deployed a multi-node OpenStack private cloud infrastructure using MicroStack, with detailed guides on networking, compute, and storage configuration.
Systems programming challenge
Custom implementations of common UNIX commands (ls, cat, grep, wc, etc.) in C — a deep dive into systems programming, file I/O, and process management.
