Ruberwa was born on August 20, 1964, in the village of Rugezi, located in the highland region of the Fizi territory in the South Kivu province.

[3] Ruberwa spent his early years in Minembwe, South Kivu before moving on to Katanga Province to finish high school and college.

Among other things, he led a delegation to Rome during his tenure to represent the Democratic Republic of Congo in the negotiations leading up to the Treaty of Rome-which was responsible for creating the International Criminal Court.

Ruberwa was eventually appointed RCD Secretary General in October 2000, which effectively made him the de facto political leader of the organization.

[10] In this capacity, Ruberwa took on the chief negotiator role for the movement at both the Lusaka Ceasefire Agreement in Zambia and the Sun City Accords in Pretoria, South Africa.

Under the Sun City Peace Deal, a power-sharing transitional government was formed and Ruberwa was named Vice President of the Democratic Republic of the Congo, along with Jean-Pierre Bemba, Arthur Z'ahidi Ngoma, and Abdoulaye Yerodia Ndombasi.

[18] After meeting with the South African delegation, Ruberwa and members of the RCD party decided to end the suspension once they secured additional guarantees for a new road map for peace.

[19] After running in the 2006 presidential elections and losing in a crowded field to incumbent President Joseph Kabila, Ruberwa decided to step away from politics and to reopen his law practice in Lubumbashi along with two additional offices in Kinshasa and Goma.

He continues to serve on several other boards such as The International Leadership Foundation, Congo Family Restoration, The Congolese National Prayer Breakfast Group, and a few other organizations.

[26] Ruberwa has been lauded for adopting a strong interdependence approach that favors empowering provincial and local officials in each province and helping them become less dependent on the national government.

Ruberwa further served as the Acting Prime Minister for several weeks between June and July 2019, while Bruno Tshibala took a medical leave of absence.

[3] In preparation for his 2006 presidential campaign, Ruberwa wrote a book titled "Our Vision for the Democratic Republic of Congo: Assessment of an Action, Outline of a Project."
