Need some guidance

Hello people,

A brief intro of mine- I am working as an Application Developer at IBM and about to complete 1 yoe.

I want guidance regarding how I can switch to companies like Goldman Sachs or similar from here.

These Fintech MNCs are my dream companies.

My major skill set- Core Java, Spring (beginner level), SQL, Reactjs.

I am actually willing to switch within this year. I am ready to give my best in preparation, just I need a proper roadmap regarding what to do and what not to do.
