OpenCraftBeruang: AI-powered financial intelligence from zero to production in 8 weeks.
Beruang is a financial intelligence platform built around live market signals, calmer portfolio awareness, and AI-supported interpretation. OpenCraft designed the system architecture, built the data pipeline, and shipped the product surface that connects market movement to user-facing decision support.

The challenge
Financial data moves fast, but most retail investment tools either overwhelm users with raw data or oversimplify into useless summaries. The Beruang team needed a system that could process thousands of market signals daily and translate them into actionable, calm portfolio awareness.
The core technical challenges: real-time data ingestion from 6 different API sources with varying latency profiles, AI-powered interpretation that stays accurate during volatile market conditions, and alert systems that catch real risks without triggering false alarms.
Our approach
We followed our standard four-phase delivery model: audit, build, test, and ship. The 8-week timeline was aggressive but achievable because we scoped ruthlessly — no feature survived unless it directly served portfolio decision-making.
Discovery & Architecture
- Mapped financial data sources and market signal requirements
- Designed event-driven architecture for real-time data ingestion
- Defined AI model requirements for market interpretation and alert generation
- Scoped the user-facing decision support interface
Core Pipeline Build
- Built real-time market data ingestion pipeline processing 50K+ signals daily
- Integrated 6 external APIs (market feeds, news, sentiment, macro indicators)
- Developed AI-powered portfolio monitoring with configurable alert thresholds
- Implemented natural language market interpretation layer using LLM chains
Product Surface & Testing
- Built the user-facing dashboard with live portfolio views and signal overlays
- Added AI-generated market summaries tuned for readability over technical depth
- Load-tested the pipeline under peak market hours (9:00-11:30 WIB)
- Calibrated alert sensitivity to minimize false positives (achieved 94% accuracy)
Launch & Optimization
- Deployed to production with monitoring and alerting infrastructure
- Ran A/B tests on market summary formats to optimize user engagement
- Established weekly model review cadence to catch drift in signal quality
- Documented operational runbooks for the client engineering team
The impact
Real-time market intelligence
The pipeline processes 50,000+ market signals daily with sub-second latency, giving users a live view of portfolio-relevant market movements without manual monitoring.
AI-powered interpretation
Natural language market summaries translate complex signal clusters into readable insights. Users reported understanding market conditions 40% faster compared to raw data dashboards.
High-accuracy alert system
94% alert accuracy means users trust the notification system. During the first month of operation, the system correctly identified 3 significant portfolio risk events before they appeared in mainstream financial news.
Production-ready in 8 weeks
From architecture to deployment in 8 weeks, including 6 API integrations, real-time processing pipeline, AI interpretation layer, and user-facing product surface. The operational runbooks enabled the client team to maintain the system independently.
