# Projects — Harshit Katheria

## double-fault-demo

**Role:** Solo project
**Year:** 2026
**Tags:** c, linux, obfuscation, anti-reverse-engineering, security, android

A signal handler that re-faults on entry, so the kernel's crash reporter tears itself apart before it can write a usable tombstone or logcat line. A reverser chasing the top frame looks in the wrong place.

**Tags:** python, pytorch, machine-learning, healthcare, explainable-ai

## Pinterest Video Downloader

**Role:** Solo project
**Year:** 2023
**Tags:** python, scraper, cli, pinterest-api

A Python CLI that pulls videos out of Pinterest without the official API. Handles the auth dance, rate limits, and the constant format-churn that breaks most Pinterest scrapers every few months.
