Hi! My mission is to build technology that advances our civilization.

Currently, I’m an engineering manager at Brex, focused on Rewards & Community. Before that, I also supported the Card Growth and Card Fraud teams, led the development of some APIs and integrations, and was the point person for receipts capture.

You can find out more about my time at Brex on The Muse and Built In NYC.

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

I love building things. My projects have received funding from Pioneer, a remote accelerator for projects and startups built by ambitious outsiders around the world.

I have a strong curiosity for the intersection of computer science and financial systems, because the creation and exchange of value is at the core of human activity. Technology has the ability (and responsibility!) to make that more efficient and accessible. I’ve enjoyed writing about these subjects for publications like Hacker Noon.

I was the first in my family to attend college. I graduated from Brown University in Computer Science & Economics, where I was also a teaching assistant, hackathon prizewinner, and founder/president of 3 student organizations.

I speak Portuguese, Mandarin, and English daily. I love to read.

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



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.


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.


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.

Built during the MarketMake hackathon. Winner of prizes from The Graph and Aavegotchi.

DeFi Terminal

Real-time data, metrics, and news for decentralized finance. Aggregating data from The Graph, DeFi Pulse, and others.



A wallet for USD stablecoins that earns interest. Starting with South America, the goal is to help people in countries like Brazil to protect the value of their savings against currency depreciation.
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). Saw ~25% WoW increase in signups on landing page since August 2020. Participated in IDEO’s Product Validation Day, among 32 selected teams from 120+ that applied for the program at the world’s most renowned design firm.
Prototyped in Brazilian Portuguese & English. Stack: Node/Express, Web3.js, Infura, Compound smart contracts & API, non-custodial wallets such as Portis/Fortmatic/Torus.


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).


Inspired by CryptoKitties, non-fungible tokens representing elements of clean energy.
Also a winner on Pioneer! 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.


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


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

Red Crypto Envelope

Conditional spending on Ethereum.

Ethereum Goals Tracker

A full-stack dApp for accountability. View on Github

Blockchain Whitepapers Written by Neural Networks

Trained an RNN on 160 whitepapers to generate some crypto-jargon from scratch.


Writer for the Brex Engineering Blog, Hacker Noon (tech blog with with over 4M monthly readers) and BecomingHuman.ai (artificial intelligence publication).
