During his tenure, the regency built its first asphalt-sealed road in Ujoh Bilang which is the regency's administrative center in 2018. The road was planned to be constructed connecting the village of Long Bagun and also the town of Tering.

He plans to also upgrade the recently-built road connecting the villages of Ujoh Bilang and Mahamak Besar, expanding it to a two-lane road, the first of its kind in the region. He stated that road constructions are needed in the regency to remove the region's remoteness and make transportation easier than previously, which consistent mostly of using boats on the river. He also stated that the road construction would make the price of goods in the region cheaper. His plan, however, was criticized by environmentalists due to fear of destruction of Heart of Borneo's jungles.

He became a representative in the newly formed Mahakam Ulu Regency's parliament in 2014 and became vice speaker of the parliament.

Bonifasius soon became involved in a swiftlet nest business and rented a cave inside the jungle, from which he harvested bird's nests. After accumulating money from selling bird's nest, he founded a logging company in 1999. His company obtained a permit to manage around 13,000 hectares of jungle in Kutai Kartanegara Regency and he also expanded his business to heavy equipments. He later became in charge of a cooperative, and then pursued a law degree at "17th August University." He also became the director of a coal trading company based in Samarinda, PT Cahaya Belawan Sejahtera until 2013.

He then moved again to the city of Samarinda to pursue vocational education until graduating in 1986. Afterward, he enrolled in Mulawarman University and studied in the teaching faculty. However, due to his mother's illness, he came back to the village and worked on a plantation instead of pursuing higher education, dropping out from the college. He also collected swiftlet nest in the jungle for additional money to support his family.
