Internal solution for extract and analyze data from many clients. The full cycle of development. I start from high-level technical specification to full implementation, deploy to production and support. Powerful multi-layer ETL system with good data acquiring (3k rps) and large data storage. The system with a low probability of lost data and fast restoring and recalculating data from any available time point.
