- Bulid from scratch all or parts of the data warehouse to improve the KPIs.
- Ensure the SLAs and SLOs of data warehouse, which will require assuming ownership and being oncall for the same.
- Gain deep understanding into Linux and understand concepts that drive performance characteristics like IO scheduling, paging, processing scheduling, CPU instruction pipelining etc.
- Adopt/build tooling and tune the systems to extract maximum performance out of the underlying hardware.
- Build wrappers/microservices for improving visibility, control, adoption and ease of use for the data warehouse.
- Build tooling and automation for monitoring, debugging and deployment of the warehouse.
- Contribute to open source database technologies that are used at or are potential candidates for use.
