OVERVIEW
Hera Finance is a Solana trading product built around fast token swaps, route transparency, and better visibility into wallet activity. The product needed more than a swap form. It also needed charting, route inspection, portfolio visibility, and reliable transaction flows.
I worked across both frontend and backend layers, building the main swap experience, send flow, dashboard, and portfolio surfaces while wiring them into Jupiter, Helius, wallet adapters, and internal API routes.
A core part of the work was turning technically dense routing and execution data into product interfaces that felt usable: route trees, Sankey-style diagrams, activity views, quote refresh logic, execution safeguards, and chart-driven reporting all inside a cohesive product surface.
WHAT I OWNED
- -Built the main trade experience across swap, send, and supporting route panels, including quote refresh logic, slippage controls, routing depth selection, and confirmation states.
- -Implemented wallet-connected execution flows for both swaps and token transfers, including simulation, fee handling, balance validation, account creation checks, signing, sending, and confirmation.
- -Developed backend and integration layers around Jupiter, Helius, and Hera endpoints for quotes, holdings, transaction history, announcements, and AMM source configuration.
- -Built supporting product surfaces such as the portfolio view, holdings and activity tables, dashboard charts, and route visualizations in default, tree, and Sankey modes.
KEY OUTCOMES
- -Delivered a broader trading product that combined execution, route transparency, and wallet visibility instead of limiting the experience to a basic swap screen.
- -Made complex routing and transaction data easier to understand through charting, route diagrams, and clearer state handling across the trade flow.
- -Shipped a full-stack Solana product surface spanning trading, portfolio, and analytics views with reusable data and state-management patterns.
