At Zoho Sheets, I architect a cross-platform pivot computation engine in Rust, C++, and DuckDB for Linux, Windows, macOS, Wasm, Android, and iOS.
I've cut pivot query time by 50% and peak memory use by 30% on 10M+ row datasets, while delivering sub-10ms p99 million-row pivot computations in internal benchmarks.
Previously at ADP's Payroll Platform team, I optimized SQL workloads over 5M+ employee records, improving average response time by 30%, and built recovery pipelines that reduced RTO to under 10 minutes.
I also build systems projects such as FastLog, a Rust, Kafka, and ClickHouse pipeline supporting 100K+ log events per second and sub-second OLAP queries over 500M+ rows.
