Freelance Security Developers Available for Hire

Yuval Kogman, Security freelance coderHire Now
Freelance Security developer in Ashburn, United States

Polyglot developer with an obsession for modularity

There's a crack in everything, and pointing those out is a lifetime pursuit. I think I have a knack for making things break, and I believe the hacker/security mindset leads to much clearer thinking even for software that isn't security sensitive. Having a clear understanding of agency, of trust, and of intended vs. possible uses is vital to writing good code. I also think the fastest way to gain technical understanding of anything is to go straight for the facts, and nowhere in software is the distinction between ground truth and beliefs clearer than in the context of infosec.

Back in 2010, I hacked our inspectorate website, making some of the people angry–I got in trouble, but I learned that security is important and it's not fine to abuse other apps in the bad way. I discovered lots security issues as of XSS, Missing Function Level Access Control, Sensitive Data Exposure, most of them on sites I use everyday such as bitbucket.org, github.com etc. https://bounty.github.com/researchers/IonicaBizau.html

Friendly old school programmer ready to teach the basics to anyone who is interested

The year my networks were hit with both the Melissa and the AnnaKournikova VBS macro viruses was the year I became curious about security (for those playing at home that was the year 2001). Now I have a Masters in Cyber Security and know that security is so much more than boring checklists, virus definitions, and patches. Security is as exciting as hacking, just more legal!
