Pausing Shopify and Starting Bug Bounty

The Shopify project is currently paused because of shipping costs rather than a technical problem. A single test package from China to the US cost around USD 28. My friend is considering using a 3PL service—renting local storage and shipping products in batches—to reduce the cost per order. I raised the risk of additional storage and operating expenses, so for now I’m waiting for his decision before we continue.

Meanwhile, learning web security and bug bounty has been rewarding. After completing more CTF challenges and revisiting the fundamentals, I’m moving from theoretical warm-up into real-world practice. I have selected a bug-bounty platform, started attempting real authorized targets, submitted my first vulnerability report, and found useful Reddit communities where I can learn from other researchers’ experiences.
