Ignore this looser first, now let's come to your question about gaining experience in real estate sector in thailand so first of all you can't work on tourist visa even if it's not paid, and if company wants to hire resources from other country why would they do visa and work permit for a person who doesn't have any work experience. My advice would be find a cyber security related job in Thailand and then there itself you can work as a free agent by associating with real estate companies and then can find work in reas estate
