Experiences

Reformulary Group

Staff Engineer

- Present

  • Architected an in-memory diffing engine to reconcile historical state changes, using Serde deserialization and zero-copy parsing to deduplicate records with controlled memory usage and reduce cost by 72%.
  • Improved maintainability with domain-specific errors (thiserror), structured logging, trait-based automocking, SeaORM, and unit/E2E tests, reducing production defects to nearly zero.

Robust Thinkers Co.

Founder & Software Engineer

- Present
  • Independently architected a cross-platform React/Rust application for web, iOS, and Android, deploying to Google Cloud Run and using AI-assisted workflows to automate boilerplate and achieve 100% test coverage.
  • Deployed an Axum backend to Google Cloud Run and Cloud SQL, routed traffic through Cloudflare, and implemented secure authentication with Firebase JWTs and custom deserialization.
