Ambitious builder who shipped a feature driving $500M in revenue at Amazon, then left to pursue bold ideas in AI. I thrive on hard problems, learn fast, and have the stamina to grind for years. Currently building Dynbox, an AI-powered file explorer—early traction was tough and we made plenty of mistakes, but each setback has helped us learn and improve the product.

Work Experience

• Feb 2025 - Present | Dynbox - Founder & CEO
  Building an AI-powered file explorer that replaces your default file system. After launching cloud version and getting 6,000 visitors from Product Hunt, we learned users struggle with local files daily. Pivoted from cloud to desktop app based on 88% weekly churn data and user feedback. Current status: 300+ users, 60k files processed, building the future of file management.
• Mar 2024 - Aug 2024 | Amazon - Software Development Engineer Intern

Philosophy & Approach

• Ship fast, learn faster: MVPs in weeks, not months. Real user feedback over speculation.
• Focus on big markets: Now target $5B+ TAM and daily pain points.
• Build for impact: Success = user problems solved and revenue, not just features.
• Data-driven pivots: Listened to high churn, pivoted quickly. Ego doesn't build great products.
