Ruiz's documented life is centered in Caracas, the capital of Venezuela, where his legal education and professional career took place. Caracas was the setting for both the university that conferred his law degree and the legal practice in which he later worked.
The Venezuelan capital also hosts the Universidad Central de Venezuela, the country's oldest university, which placed Ruiz within one of the principal centers of legal education in the country.
Ruiz completed a Juris Doctor at the Universidad Central de Venezuela, with the degree recorded as 1960. The university was founded by royal decree on 22 December 1721 as the Royal and Pontifical University of Caracas, and during the colonial period it was the only university in the Venezuelan province. Its early curriculum included theology, law, and medicine, reflecting the Catholic and royal character of the colonial institution.
After Venezuelan independence, Simón Bolívar promoted an academic renewal of the institution, which later took the name Central University of Caracas. The reform aimed to turn the university into a self-supporting scientific and academic center, adding new courses and introducing teaching in Castilian rather than Latin. Ruiz's law degree was therefore earned within this long university tradition in the Venezuelan capital.
Ruiz was admitted to the bar in Venezuela in 1960, the same year his Juris Doctor from the Universidad Central de Venezuela was recorded. Admission to the bar marked the beginning of his professional life as a lawyer in Caracas.
Ruiz later worked as a partner of International Law Practice Escritorio Juridico Economico, a law practice based in Caracas. The firm's name identifies it as an international law practice, and its office was located in the Las Mercedes district of the capital.
The Caracas setting connected Ruiz's legal training with his professional practice, since both his university education and his work as a partner took place in the same city.
