Hello Jose,
B.Tech in computer science is a better option as compared to B.Sc course. B.Tech is a technical professional degree (engineering) which has good career prospects and it gets completed in 4 years as against the B.Sc (graduation degree in Science) which is a 3 year course. After doing a B.Sc to build a successful career, you will need to pursue post graduate studies in a subject of your choice since the B.Sc alone is not job oriented, unlike B.Tech which is a job oriented course.

You can do MBA in finance or can prepare for competitive exams to get a job in the banking sector.
