Career
Technical lead/architect, Rio AI
2021 - present
- Migrated the data platform from Snowflake to Redshift, trading raw compute for the precision of AWS-managed zero-ETL integration — a shift that cut data-related bugs reported that year by 75% compared with the year before
- Built an AI- and Sentry-driven error-remediation system that automatically diagnoses and resolves runtime errors, cutting response time to production bugs to 15 minutes
- Planned and led the rollout of a new design system for a full product redesign spanning more than 1,000 React components, sequenced for a smooth, incremental migration
- Drove adoption of AI workflows via an internal Slack app that sped up routine work: ticket refinement, database lookups, quick analytics, and development estimation
- Replaced QuickSight with in-house AG Charts dashboards, taking full control of every visual component to ensure a consistent look and feel across the product
- Developed an AI-powered data-analysis assistant using AWS Bedrock AgentCore and real-time HTTP streaming
- Migrated 50+ repositories from Bitbucket to GitHub and consolidated core services into a monorepo to streamline CI/CD and code sharing.
