IDRXY
AI-assisted build (vibe coded) using Codex and Cursor. Built through iterative prompting and refinement; AI tools contributed to the implementation.
The problem
Rupiah strength is often judged only against the US dollar. A basket-based view, similar in approach to DXY, helps show how the Rupiah moves against multiple currencies.
How I solved it
Implemented a weighted geometric index and a Supabase-backed dashboard. Added paginated snapshot reads, timestamp-tolerant comparisons and distinct rendering for synthetic chart segments.
- Weighted geometric currency index
- Timestamped snapshots and explicit synthetic data
The results
- index + reference currencies
- 9 + 12
- snapshot cache duration
- 60 sec
Delivered a nine-currency weighted index and 12 additional FX references, with Supabase snapshot retrieval, 1,000-row pagination and a 60-second data cache.
Evaluation context. A portfolio index implementation, not an externally validated official index. Interpolated chart points are synthetic; feed completeness and live deployment were not verified.
