> Security Researcher/Developer with a knack for reversing antibots scripts and helping the good guys win the cat-and-mouse game.

Location: San Francisco, California, United States
Profile: https://flows.cv/erikdominguez

My professional life revolves around the fine line of being a professional TOS breaker and a Security Researcher with a strong focus on anti-bot technology.

My primary programming languages are NodeJS and Python, even though most of my time is spent in NodeJS reversing numerous types of antibot Javascript scripts.

I reverse antibots scripts to learn all about the myriad ways they implement fingerprints mechanisms inside their Javascript scripts. Some of my interesting work can be found at my blog https://www.botting.rocks.

Experience reverser in all types Javascript ranging from simple obfuscated Javascript scripts all the way to complex obfuscated Javascript Virtual Machines.

Currently learning MLIR and LLVM and looking for any opportunities that revolve around bot mitagation, fingerprints research and collector, reverse engineering web apps.

## Work Experience
### Senior JavaScript Reverse Engineer @ Unknown
Jan 2019 – Present
As an independent JavaScript Reverse Engineer, I have specialized in countering advanced anti-bot technologies for a diverse set of clients, primarily in the retail and pricing intelligence industry. My work has directly addressed solving questionable security measures implemented by leading anti-bot providers such as ShapeSecurity, ThreatMetrix, Incapsula, Nudata, and Cloudflare. Key achievements include:

- Anti-Bot Reversal: Successfully reversed sophisticated anti-bot mechanisms, enabling the development of a request-based fingerprint generator that bypasses security measures efficiently.

- Retail Bot Support: Provided critical support for retail automation products by reversing anti-bot protections on target sites.
