Production backend engineer at Intuit. Outside of work, I build Rust systems projects focused on indexing, data pipelines, caching, benchmarking, and developer tooling. I care about measurable performance, operational correctness, and turning slow workflows into simpler, more reliable systems.

TTAPI source is private; public materials use synthetic or non-sensitive examples.
- Built and shipped backend changes behind feature flags to make financial feed behavior safer to roll out and easier to validate in production.
- Worked on Shopify fees ingestion and payout enrichment across environments and deployment stages.
- Contributed to transaction list aggregate/parity improvements in QuickBooks backend systems.
- Indexing, search, and data-intensive backend workflows
- Performance measurement, caching, and reproducible benchmarking
- Data pipelines, reliability work, and developer tooling
- Measure first: benchmark before and after changes
- Prefer clear APIs, strong tests, and predictable operational behavior
- Ship incrementally with feature flags, small PRs, and straightforward rollouts
