At Bloop, I engineered the platform’s Member-Get-Member referral ecosystem, which directly drove a 200%+ increase in sales after deployment. I also built product flows connecting a .NET Core backend with Next.js web and React Native / Expo mobile frontends.

At Bloop, I developed social features including nested comment threads and a real-time user-mention system. I also built a product variant selector across platforms to streamline the purchasing funnel.

At Sellabroad, I built and deployed 40+ responsive web pages and reusable UI components for cross-border e-commerce. On my Explora project, I integrated Stripe for end-to-end payments and served as Scrum Master for a 10-member development team.
