Project Narrative & Background
Rumah Ringkas brings corporate-grade financial discipline to family budgets. Designed around the classic 'Envelope Budgeting' methodology, family members can quickly type natural-language notes (e.g. 'Makan siang 25rb pakai GoPay'), which the system automatically parses into category, amount, and account balances. The platform aggregates Cash, BCA, GoPay, Jago, Bareksa, and Debts into a live Net Worth indicator.
Architectural Context: Household wealth management platform linking multi-member financial records into a single family dashboard.
The Operational Challenge
Multiple family members (Danu, Sari, Ibu Tuti) needed a frictionless way to record daily transactions instantly without complicated accounting forms.
The Engineering Solution
Built a mobile-first PWA featuring a 'Catat Cepat' natural language parser, visual envelope budget caps, multi-account Net Worth calculator, and granular family data privacy controls.
Key Architectural & Design Decisions
- 01Built a custom Regex parser for Indonesian financial shorthand ('25rb', '12jt', 'Gaji masuk')
- 02Implemented client-side reactive state sync across household member records.
- 03Added CSV export and instant data-reset controls for family data sovereignty.
Key Deliverables & System Capabilities
- Natural language 'Catat Cepat' transaction parser with automatic category & account mapping
- Visual Envelope Budgeting Engine with dynamic weekly/monthly cap calculations
- Multi-Account Net Worth Aggregator (Cash, Bank, E-Wallets, Investments, Utang & Piutang)
- Interactive 6-Month Cashflow & Expense Breakdown analytics using Recharts
Project Outcome & Operational Impact
Adopted for daily family financial orchestration, reducing monthly unbudgeted expenses by 22%.
