Stealth Startup
Software engineer & co-founder
Context
A platform presenting blockchain wallet, contract and transaction data alongside market and news context. Public explorers were slow and expensive to query at the granularity we needed, so we built the data layer ourselves rather than consuming someone else's.
Responsibilities
- Implemented a version of the Ethereum runtime as a Go library, removing the database Ethereum normally depends on so it could be consumed directly from microservices.
- Designed an aggregate-oriented data model around wallets, contracts and transactions, using an address-based representation of transaction data.
- Built a service integrating centralised exchanges for real-time market data.
- Built a news ingestion service running four times daily, presented alongside the chain data.
- Shared technical direction and scope planning with my co-founder under real time and budget constraints.
Achievements
- Reduced time complexity and compute cost relative to querying public infrastructure.
- Produced data representations that were frequently more accurate than standard explorers such as Etherscan.
- Practical experience in time and resource management, cooperation, and open communication in a small team.
