Current Projects

One of my main current projects is Solid Comics, where I manage the operational and financial side of the business. I oversaw the full legal setup—forming the LLC, securing vendor licenses, and completing required state and tax filings. I also build pricing models, structure our sales strategy, and work on improving revenue across online listings and live auctions. My business partner focuses on inventory acquisition and day-to-day product management, while I handle the financial systems, compliance, and growth strategy that keep the operation running smoothly.

Coolax business work

Past Projects

One of my key past projects was Coolax, a business I owned and operated from 2017 to 2022. I ran every part of the operation—finances, budgeting, sales, fulfillment, and day-to-day management. Becoming the owner of it in middle school and growing it through high school gave me early experience in real business operations and financial discipline. I closed the business in 2022 to focus on college and larger projects, but the hands-on skills I built continue to shape how I approach work today.
