​$2000 in debt to $27,000 profit in 2 months. What do you think I should do next?

I’m a 21-year-old full-time college student who struggled to find a job in graphic design or web development. To make ends meet, I began using credit cards for their signup bonuses. Unexpected expenses like rent and car repairs pushed me into $2,000 of debt. I took a night job at Amazon and started a side hustle reselling warehouse technology, which required me to take on an additional $3,000 in debt for inventory.

Fortunately, I found reliable buyers and cleared all my debt within two months, earning a profit of about $27,000. Now, my scholarships fully cover my education and living expenses, and I have $27,000 saved up. I would continue what I do now, but the market is running dry ( I set up some scraping bots to find the items for me, so I quickly bought up everything I could ). I expect maybe another $20-30k over the next 10 months.

I am still learning web development on the side and I have a plan to start an agency this year. However, for now I want another business I can start with the capital that I have. Do you have any ideas on what I can look into or how to make the most of my situation?
