TECH STACK
OVERVIEW
Ern combined two connected surfaces: a marketing site that explained the product thesis clearly, and a dashboard where users could connect wallets, deposit stablecoins, track returns, and withdraw while seeing live BTC and yield data.
I worked across both surfaces, building the landing experience, simulator, performance views, FAQ and support sections, plus the dashboard flows for deposits, withdrawals, balances, claim handling, and transaction history.
A major part of the work was making a technical yield strategy feel legible through interactive comparisons, live price and APY feeds, and a cleaner on-chain user flow instead of a vague DeFi pitch page.
WHAT I OWNED
- -Built the main product site across hero, APY stats, analytics, simulator, historical comparison, how-it-works, why-Ern, FAQ, and support surfaces.
- -Implemented the dashboard experience for wallet connection, token selection, approvals, deposits, withdrawals, claim handling, balances, earnings cards, and responsive chart modules.
- -Integrated live and historical data sources including Aave APY data, BTC price feeds via Alchemy-backed API routes, and yield-calculation logic used inside the simulator and comparison views.
- -Built on-chain transaction history flows by fetching and watching deposit, withdraw, yield, and approval events, then surfacing them with explorer links and near real-time updates.
KEY OUTCOMES
- -Delivered a clearer product journey from explanation to action by connecting the marketing site and dashboard into one coherent experience.
- -Made the yield strategy easier to understand through simulator-driven comparisons, live BTC pricing, APY surfaces, and historical performance views.
- -Shipped a usable on-chain dashboard around deposits, withdrawals, yield claims, and transaction history instead of stopping at a marketing-only frontend.
