Pangu Terminal

Resource-optimization platform for Wuthering Waves

Full-stack Rails application that reconciles game progression requirements against player inventory, calculating exact material deficits and detecting synthesis opportunities across 50+ items.

• –Game upgrade paths pull from 10+ overlapping cost tables with no single source of truth, so I built a service layer that queries each table in isolation and keeps the planning logic independently testable
• –The REST API returns a material deficit and its farming source from a single endpoint pair, so clients have everything needed to render a farming view without a second request
• –Inventory edits trigger real-time re-renders of entire synthesis families via Hotwire Turbo Streams; plan output is JSONB-cached so the page reads from cache rather than recomputing on load
• –96%+ service layer test coverage across three planning services — several cost calculation edge cases only turned up once formal tests replaced manual spot-checking
• –Surplus lower-tier materials can be synthesized 3-to-1 into higher tiers, but only if the math accounts for cross-rarity EXP equivalence — the planner reconciles both before marking a plan complete
