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.

Open to: Backend, platform, and performance-oriented infrastructure roles • Location: Remote or hybrid (SF Bay Area)

• UFFS — Ultra Fast File Search (Rust, public code)
  Benchmark-driven NTFS search engine with direct MFT parsing, persisted cache, and daemon-backed query flow.
  • Repo → https://github.com/skyllc-ai/UltraFastFileSearch

• TTAPI (private code, public-safe materials)
  Architecture notes, one-pager, and demo for a Rust data/analytics workspace.
  • One-pager → https://githubrobbi.github.io/rust-systems-portfolio/ttapi-one-pager.html
  • Demo → https://githubrobbi.github.io/rust-systems-portfolio/demo/ttapi-demo-script.html

• Portfolio / write-ups
  • Portfolio → https://githubrobbi.github.io/rust-systems-portfolio/
  • Panic-Free Rust APIs → https://githubrobbi.github.io/rust-systems-portfolio/posts/panic-free-rust-apis.html
  • Bench-First Rust Development → https://githubrobbi.github.io/rust-systems-portfolio/posts/bench-first-rust-development.html

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
