Personal Projects

Real-Time Task Orchestration & Execution Dashboard (Flask + SocketIO)

Developed a Flask and Socket.IO-based system for executing and monitoring automated backend tasks in real time. The platform supports background job execution, live log streaming, task state tracking, and step-level execution visibility, alongside remote file inspection and editing tools.

Scalable Web Phishing Detection System

Built a scalable system to automatically scan and analyse large volumes of websites to identify potential phishing activity. The solution applied automated pattern detection and rule-based validation to flag suspicious domains and content, helping surface potential security threats efficiently across high-volume datasets. Automatic reporting of confirmed phishing sites has reduced the number of sites from hunderds to single digits.

Field media ingestion server

Built an end-to-end media management system combining a GoPro ingestion pipeline with a web-based archive for ski footage and resort data. The ingestion tool processes and organises raw video content into a structured format, which is then surfaced through a web application that allows users to browse footage alongside contextual ski resort information.
