Challenges

  • Large part of our backend flow is not simply data retrieval, but aggregation, calculation, and processing to be able to provide users with complete information. If this is not enough, it has to be done quickly and reliably
  • We brought down the computation of a valuation from a few weeks to some tens of a second. We need to continue the process as the amount of data grows, together with its complexity, and large part of it needs to be processed in runtime

Technologies and experience

  • PostgreSQL, Cassandra
  • RESTful API design and patterns
  • Backend and database architectures
  • OO PHP, Python, (C++ as a plus)
