Hi all,
I’m looking for an experienced Bubble.io developer to build an MVP for a tool called BTS – Biglin Targeting System, a decision-support tool used in underground mining to rank drilling targets.
You do not need mining experience — just strong Bubble skills, good logic, and clean workflow design.
This is a lean MVP to keep cost/time low.
1. User Authentication
Email/password login
Admin + Standard user roles
2. Drill Target Form (CRUD)
Users should be able to create, edit, and delete drill programs.
Fields include:
Mine Name
Target Name
Lode / Area
Total Metres
Cost per Metre
Drilling Rate
Estimated Ounces
5 scoring inputs (each 1–5)
3. Multiplicative Scoring Engine
Each target is ranked using the formula:
Final Score = Geo × Strategic × Access × Efficiency × Risk
Admin should be able to:
Rename the 5 criteria
Toggle each criterion on/off
Adjust score ranges (e.g., 0–5, 1–5, 0–10)
No additive model.
No weightings system.
4. Results Page
A dashboard that shows:
All targets/programs
Their final multiplicative score
Priority label (P1, P2, P3 etc)
Cost-per-ounce calculation
Basic drilling time estimate (Metres / Rate)
Drill program schedule
Users should be able to:
Sort by score
Search/filter
View target details
5. Export Features
Export results to CSV or Excel
(Does NOT need PDF; optional later.)
6. Basic UI/UX
I do not have UI designs — I’m happy with simple, clean, functional layouts.
Bubble’s default components are fine for MVP.
What I Provide
Full scoring matrix
Excel version of BTS
Logic for multiplicative scoring
Clear rules for cost-per-oz and schedule
Ideal Developer
Strong Bubble experience
Comfortable with database structure + workflows
Can deliver a working MVP quickly
Good communication
Mining knowledge is not required.
Budget
$2,000–$6,000 AUD for this simplified MVP.
