PROJECTS

Motion Detection Viewport Tracking System (output on GitHub) o Collaborated with other developers to develop a motion detection tracking system which follows the main action in a sports video

Trip Itinerary Web App (easyexplore.vercel.app)

o Collaborated with other developers to develop a trip itinerary web application using Next.js

(Part time)

IoT Security Monitoring and Threat Detection Pipeline o Built an end-to-end IoT security monitoring pipeline using a Raspberry Pi generating simulated MQTT sensor data, an AWS-hosted Mosquitto broker, and a Dockerized Suricata + ELK stack. Developed and validated custom Suricata IDS rules through live attack simulations and pcap replay, detecting MQTT floods, malformed JSON, and buffer-overflow probes. Created Kibana dashboards to visualize alerts, message flows, and overall system health across the pipeline. FAMILIAR WITH
