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
Led the launch of a new feature on Amazon's global retail platform, driving
$500M in annual revenue. Key insight: Learned how to build at massive
scale with zero-latency requirements. Realized I wanted to build my own products
rather than work on someone else's vision.
- Aug 2023 - Mar 2025 | Flag4jobs - Co-Founder & Software Engineer
Built and launched a cybersecurity challenge platform, growing to 450+ users
and 20+ interactive challenges. Generated revenue through corporate sponsors.

decision.
- Jun 2023 - Feb 2024 | iGEM - Software Engineer
Developed an event app supporting 10,000+ users, revamped CI/CD to cut deployment
time by 80%, and integrated Stripe payments. Impact: Boosted profit
margins significantly through automation.
- Jun 2022 - Sep 2022 | Château du Hallay - Software Engineer

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.
