Social collaborations

Yago Hansen has been part of and has collaborated from a very young age with associations and non-profit organizations, NGOs, and collaborating entities.

Ngoc Quy Orphanage Vietnam

Visit galleryVisit YouTube


2019 - 2019

During the year 2019 I undertook a trip to Vietnam with the idea of starting a 45-day period of volunteering in that beautiful country. After a couple of weeks of volunteering as an English teacher for a local organization I discovered the Ngoc Quy orphanage in a depressed area in the Saigon region of southern Vietnam. I offered the Vietnamese couple who run this Buddhist orphanage to volunteer for the children, acting as an English teacher and helping as necessary. I spent almost a month in the orphanage, something that filled me with happiness and inner peace. Thanks Ngoc Quy! If anyone wishes to contribute to the orphanage, I will send their donation to this beautiful community.

Comunidad Ética hacker


2019 - Present

The objective of Hacker Ethics is to educate and protect to prevent cybercrime, serve as a channel of help to affected users and make the hacker community known with its ethical values. My function in this community is to help in the project management.

ASION (oncological children association)


2017 - 2017

Volunteer activities have always filled my soul, but especially those related to children with special needs. After my experience with APANOCA in Tenerife I always wanted to repeat a volunteer with sick children. Volunteer work in this type of association encompasses different functions: the main one is to go to hospitals to play with the children or simply to distract them from their routine, but also to help in fundraising activities, help in administration, etc. The whole experience is worth it.

APANOCA (association of parents of oncological sick children)


22-24 years old

The experience in this association meant a lot to me. APANOCA is an association that helps families with children with cancer to make their child’s illness more bearable. My job was to give support class to Sergio, a wonderful and strong seven-year-old boy with leukemia, coming to his house every week to review the school subjects, since he couldn’t attend class. Sergio beat his cancer!

Marine Red Cross

Marine lifeguard, mariner

13-14 years old

From a very young age I discovered volunteering. At the age of 13 I entered the Red Cross of the sea with the intention of meeting people, learning first aid and obtaining the title of seaman and skipper of inflatable boats. It was a great experience and I learned a lot from it.

International Boy Scouts Group


10-12 years old

From a very young age I joined the Boy Scouts International group in Las Palmas de Gran Canaria, doing a lot of activities such as hiking, camping, group activities, volunteering, etc.
