Summary
🤩
Rockstar🎓
Top SchoolSelcuk Aya is a Principal Software Engineer based in Redmond with eight years focused on storage and database kernel internals and a long history of shipping high-performance data systems. He has driven major features at Snowflake—file formats with compression blocks, Parquet/iceberg integration, pushdown filter optimizations and dictionary-encoding improvements—that reduced IO, storage costs and directly influenced company results. Prior roles at Google and Oracle saw him work on large-scale SQL engines, Gmail backend storage, Exadata flashcache and buffer cache internals, giving him deep C/C++ and low-level systems expertise (assembly-literate) alongside Java. He excels at understanding and evolving large, legacy codebases, often owning core scan/insert execution paths and leading technical efforts across teams. Colleagues rely on him to translate kernel-level performance work into production features that scale for cloud data platforms.
