Tan Arin
Frontend Engineering Leader

I build conversion-driven product experiences for AI, fintech, and Web3 teams.

I partner with founders and product orgs to ship UI architecture, design systems, and growth experiments that stand up to scale. My products have supported hundreds of thousands of users and more in transactions across marketplaces, SaaS platforms, and DeFi protocols.

  • Cut DeepVest's load times by 70% while doubling conversions for its investment AI platform.
  • Led handle.me's frontend at Kora Labs, supporting 200K+ NFT owners with secure serverless integrations.
  • Bootstrapped NotesBot into a revenue-generating SaaS serving 200+ communities with AI meeting summaries.
