AI-Assisted Development of a High-Performance Market Data Platform on the BEAM

EXANTE is a global fintech brokerage that provides access to thousands of financial instruments worldwide through a single, unified platform — including stocks, ETFs, bonds, futures, options, and currencies. This talk explores the practical use of AI-assisted code generation tools and analysis in the development of TickDB, a high-performance system for real-time storage and processing of market data, one of Exante services. TickDB ingests, aggregates, and serves tick-level data including quotes, trades, bonds, options, and fundamental indicators, with support for time-based aggregations from minutes to days. We will share how AI tools are applied to generate production-ready code, analyze complex Erlang codebases, and automatically create internal common test suites, improving development speed, code quality, and long-term maintainability in a distributed, data-intensive system built on RocksDB.
