A. Iskandar G. Intan, who is often known as Mr. Arnold, completed his formal education majoring in architecture in 2003 at Petra Christian University, Surabaya. Several experiences handling freelance projects before graduation made him realize the essential competencies that an architect must master, particularly those related to construction management, which he studied from 2004 to 2006 at the same university.

In 2005, Mr. Arnold founded AIGI Architect + Associates with a vision that emphasizes values ​​related to project owners and building users. The firm started with handling residential projects and later expanded to commercial, institutional, hospitality, and master plan projects in various cities in Indonesia.

As a professional, Mr. Arnold actively participated in the Indonesian Architects Association (IAI) organization in 2009 and obtained professional certification in 2014, which he maintains to this day. Additionally, he began teaching at several universities in 2016 and participated in pioneering the Architectural Profession Program (PPAR) in 2018 at Petra Christian University, Surabaya. This participation confirmed AIGI Architect + Associates as an official internship place for architects seeking professional certification in Indonesia.
