Software Developer Intern @ Rimo (Dec 2025 – Present)
- Built an automated prompt-optimization system that reduced manual iteration cycles by 90% and improved pass rates by 25%, backed by regression validation.
- Shipped an evaluation workflow with multi-dimensional scoring and clean train/validation/test splits across multiple meeting types, plus a simple “/add-scenario” flow so non-technical users could configure scenarios in minutes.
- Built and shipped a Slack translation product supporting 25+ languages with runtime provider switching; deployed to the Slack Marketplace.
- Reduced translation latency by 50% and cut API costs by ~70% using structured outputs, retry deduplication, and skipping non-translatable content.
- Delivered a tiered subscription monetization system with usage tracking, quota enforcement, and an in-product dashboard.
- Fixed production edge cases (long messages, Unicode counting, formatting restoration, Slack subtype handling) while maintaining zero-downtime stability.
