About the client

BMLL Technologies Ltd is a scale-up Financial Technology firm, based in London. BMLL was incorporated back in 2014 and is a spin-off from the signal processing labs at Cambridge University. BMLL has rapidly expanded its staff and client reach since then. BMLL looks to combine software, hardware, and analytics on a single, scalable platform. Our client provides a powerful platform for analyzing Limit Order Book and Complementary Datasets in the cloud. However, building up this bedrock of data for the analytics to run on was the challenge.


Generating insights from the data in the financial markets is challenging: over 150 different trading venues, over 10,000 liquid tickers, different exchange feeds, protocols, data structures, and trading rules which change over time.


Creating multiple parsers to analyze and normalize each of the datasets to build up a solid history of data for the platform.


The work of our team boosted the number of parallel developed parsers. The product was launched on-time with an impressive amount of data available from day one. Research scientists can quickly and efficiently investigate the problems their organization faces.
