Hello! My mission is to build technology that generates economic value and helps advance our civilization.

I am currently an Entrepreneur-In-Residence with Human Capital and Bain Capital Crypto, exploring new ideas in web3.

Since becoming intrigued by Ethereum in 2017, I started building independent projects in my spare time. Some of my favorites include: A no-code token minter on Polygon (#1 on Product Hunt), bridge search tool (winner at Jump Crypto hackathon), payments with stablecoins (winner at HackMoney), and a climate NFT game (winner on Pioneer in 2018). After attending 10 crypto hackathons (and using prize money to boost my morale through crypto bear markets), I turned my nights and weekends into my full-time endeavor in 2022.

Previously at Brex, I was responsible for the Card Fraud, Card Growth, and Rewards teams as an engineering manager. I joined as an early engineer focused on receipts, ERP integrations and helped build our first-ever external API. You can find out more about my time at Brex on Built In NYC.

Prior to that, I was a backend engineer at Apple Siri working on TV & Flights search, and at Microsoft building cloud infrastructure & developer tools.

My parents rode the “Made in China” wave to sell Chinese-manufactured goods in Brazil. I grew up speaking Chinese and Portuguese natively, so English is my third language. I also saw the Brazilian Real depreciate by 50% against the US dollar, and the anxieties it caused my family’s importing business.

I was the first in my family to attend university. I graduated from Brown, where I was also a CS teaching assistant, hackathon addict, and founder/president of 3 student organizations.

I have a strong curiosity for the intersection of computer science, financial systems, and liberal arts. I’ve enjoyed writing about these subjects for publications like Hacker Noon.

I love to read, engage with builders (especially from underrepresented groups), and frequently practice HIIT and martial arts.

Say hello at julia@juliawu.me! Thank you for stopping by.

Projects

Began during HackMoney, a month-long hackathon for decentralized finance. Highlighted by the Compound Protocol as one of their favorite projects at the hackathon.
It became a top 20 project on Pioneer (out of ~1k). Participated in IDEO’s Product Validation Day.
Prototyped in Brazilian Portuguese & English. Stack: Node/Express, Web3.js, Infura, Compound smart contracts & API, non-custodial wallets such as Portis/Fortmatic/Torus.

Trophy Case

Demo | Github | Showcase

Created at NFT Hack 2022: A dead simple way for developers to let users mint NFTs from in-app achievements, and a wallet for users to view all their achievements & discover others with similar interests.

Winner of “Best Use of Polygon” and IPFS prizes. Built with Grace Wang and Melanie Tam.

Yield-generating Gift Cards on Terra

Demo | Github
UST gift cards that earn yield on idle funds. Built during Miami Hack Week (Jan 2022) at the Spacecamp / Terra house.

Voltaire

Demo | Description

A wallet earning yield from money markets on Polygon (Ethereum scalability solution). Integrated with Aave, Zapper’s data API, and the Torus wallet for seamless/passwordless login using social accounts.

Built during the Scaling Ethereum hackathon. Winner of the Torus sponsor prize.

Poolside

Demo | Description

Poolside is the source for new listings and trending assets in decentralized finance. Find and search through real-time data aggregated from The Graph, Uniswap, 1inch, Aavegotchi, Coinmarketcap and more.

Temaki

Demo | App
I got curious about the Zapper (DeFi) API and wanted to experiment with reading wallet and other on-chain data and try “zapping” into liquidity pools. Prototyped a simple web app that reads wallet holdings on Ethereum, Polygon, and Binance Smart Chain. Also implemented UX for opening Sushiswap positions on Polygon.

Superset

Product Search for peer-to-peer marketplaces. Product Hunt | Demo
Winner on Pioneer. Presented in online demo day to audience of 400, including Laura Deming (Longevity Fund), Tyler Cowen (economist), Zach Sims (Codecademy) and Patrick McKenzie (Stripe).

CryptoRenewables

Inspired by CryptoKitties, non-fungible tokens representing elements of clean energy. Winner during the first Pioneer tournament. Blog

Brex Insights Dashboard

Self-driven project while interviewing at Brex. I read every article I could find about Brex, dug into the company’s customer support pages and “reverse-engineered” the Brex Dashboard while incorporating some ideas for new features.

Compound Inspector

Used Compound.js to build a simple UI for querying account, cToken and market history data from Compound.

SnapMed

Real-time, remote “office hours” with verified medical experts. During COVID-19, we hear a lot of advice/news, but don’t always know what’s accurate. So SnapMed is here to democratize instant access to reliable information. Built with 3 teammates during a COVID-19 hackathon. Devpost

ShopNet

Classifying products with using fast.ai’s deep learning libraries.

Red Crypto Envelope
