ARJUN JUNEJA

Software Developer — Reverse Engineer — Electronics Enthusiast

About

Hi, I'm Arjun, a 19 year-old self-taught developer and reverse-engineer.

I primarily do low-level programming, low-latency optimizations, reverse engineering, and systems work. I specialize in Windows internals and spending time on reverse-engineering software and security products. I also enjoy making high-performance applications applicable in graphics programming and finance.

I began in my childhood electronics lab, where I first started taking things apart and building projects [look at my electronics archive]. I now share my discoveries through my [blog] and writing technical reports and research papers.
