Baju’s professional journey as an architect started in 1994 after he graduated from Delft University of Technology, The Netherlands. In 2001, Baju founded PT Imago Karya Persada, an architecture and interior firm with 2 other partners. Prior to founding PT Imago Karya Persada, he worked among others at Ronald Knappers Architecten Bureau as a junior architect in Leiden, The Netherlands, at PT Grahawita Santika as an in-house architect in Jakarta, and at PT Arthamulia, a furniture factory as a principal of design development. Through the years, Baju has designed a number of residences, office buildings, hospitals, hotels, and laboratories. In some projects, Baju had the opportunities to design and build his own design into reality. These opportunities have sharpened his capability and sensibility in design and his managerial skills in building construction. In 2015, Baju joined PT Dex Solusi Transit which challenged his experiences contributing in designing and planning urban transit areas. This long journey has brought him to experience architectural and interior design, and understanding overall urban design concepts, objectives and critical issues and applying knowledge to tasks and assignments.
