DeFi vault product — private vault access, TVL and allocation dashboards, deposits and redemption states.

Overview

A DeFi vault product where users deposit into managed vaults and follow TVL, allocations and their own positions. My work focused on the private vault and dashboard experiences — the surfaces where trust is won or lost.

Much of the job was reliability: protocol APIs are not always available or consistent, and financial numbers on screen have to be right, formatted correctly, and honest about their loading and error states.

My role

Full-stack engineer on vault and dashboard experiences.

What I shipped
  • 2FA-gated private vault access
  • TVL and allocation presentation across vaults
  • Fallback handling for protocol API failures
  • Consistent financial formatting across the dashboard
  • Deposit and redemption state flows
  • Reliability-sensitive user feedback — loading, pending and failure states that don't lie
Engineering notes

Protocol APIs fail or lag; the dashboard needed graceful fallbacks so a flaky upstream never rendered wrong numbers as if they were fresh.

Redemption is a multi-step, time-dependent state, not a button — presenting it truthfully mattered more than making it look instant.
