One planning surface
Odds, equipment, AFK time, recommendations, progression, and journals no longer require disconnected calculations.

Running product
Planning, not guesswork.
The live product combines guided setup, target search, probability estimates, recommendations, AFK planning, journals, and shareable community workflows in one responsive interface.

Choice / time
The problem
Raw odds do not answer the practical question.
Players need to know more than a nominal drop rate. Equipment, progression stage, boosts, cast speed, target rarity, and available time all change whether a setup is useful. The product turns those variables into comparable scenarios while keeping uncertainty visible.
My contribution
Product system and decision experience.
I shaped the product around guided decisions rather than a single calculator: target-fit recommendations, current-versus-optimized comparisons, AFK estimates, progression guidance, and shareable state.
The work spans TypeScript product logic, Next.js interfaces, bilingual content, responsive interaction, structured metadata, security communication, and production operation.

Decision flow
Context before recommendation.
- 01 · GoalSelect a target, progression stage, or planning task.
- 02 · SetupDescribe equipment, boosts, speed, and relevant modifiers.
- 03 · ModelCalculate effective probability, expected casts, and time.
- 04 · ComparePlace current, reduced-cost, and optimized scenarios side by side.
- 05 · DecideAct on an estimate that names its assumptions and uncertainty.
Product outcomes
Guided complexity
Beginners can start with a guided setup while experienced players retain access to advanced modifiers and comparisons.
Portable decisions
Shareable state and community builds let a useful configuration travel without requiring a game account.
Result
A probability tool that supports a decision.
The production suite now spans 16 routes and 62 TypeScript source files across calculation, onboarding, recommendations, progression, route planning, journals, community workflows, and supporting content. English and Indonesian interfaces serve the same product model.

LiveProduction deployment
Honest boundary: results are probability estimates, not guaranteed game outcomes. Game data and mechanics can change, so assumptions and update dates remain part of responsible guidance.
