Engineering at CoinTracker
Engineering team and processes

We're a small team with minimal process. We have continuous integration, unit tests with >80% coverage and multiple daily automated deployments to production. To stay organized we do weekly goals and async daily stand-ups. Engineers take end-to-end ownership on projects.

Technical Challenges

Our technical challenges include big data, advanced algorithms, scalability, performance, and more.

We integrate with dozens of exchanges (e.g. Coinbase, Binance, etc.) and blockchains (e.g. Bitcoin, Ethereum, etc.). Some integrations require thorough understanding of blockchains. Once users connect their wallets and exchanges we continuously keep connected accounts synchronized. Some of our users' accounts (like algorithmic traders) contain hundreds of thousands of transactions, so designing for performance and scalability throughout the system is critical.

To accurately compute investment performance and capital gains we have to auto-classify transactions amongst different wallets as transfers between them. We track cost basis across a given user's transaction history, supporting different cost basis methods, base currencies (both fiat and crypto) and countries. For our paid tax product, we algorithmically implement tax rules to automatically calculate users' capital gains on their transactions. Correctly calculating cost basis also requires us to store and process the entire price history for every cryptocurrency that exists — a multi-billion data-point problem.

Projects you might work on
  • Implement real-time transaction synchronization with blockchains and exchanges.

  • Develop a smart order routing platform to enable cryptocurrency trading across exchanges, taking into account full transaction history, tax lots, fee detection, arbitrage, slippage, and more.

  • Implement tax loss harvesting to reduce capital gains taxes for cryptocurrency users.
