This creates operational friction, audit risk, and uncertainty about what exists, where it is, and how it got there. Compliance data is scattered across systems and formats, making audits reactive rather than continuous.

Approach

We built Oeno as a production-grade operations platform, designed around correctness, traceability, and real-world cellar workflows.

Principles:

• Correctness over convenience — data must be trustworthy
• Traceability is the foundation — immutable production events
• Mobile-first for the cellar floor — where the work happens
• Compliance-ready by design — not an afterthought

Production-Centric Data Model

• Lot-based tracking across all stages of production
• Container-aware inventory (tanks, barrels, bins, bottling runs)
• Explicit handling of splits, blends, losses, and transfers
• Immutable production events for full historical traceability
• Ability to reconstruct inventory state at any point in time

Multi-Tenant Architecture

• Secure tenant isolation at the database layer
• Role-based access for cellar staff, managers, and compliance users
• Shared codebase supporting wineries of varying size and complexity
• Architecture designed for multi-site and future expansion

Mobile-First Cellar Workflows

• React Native app optimized for fast, on-floor data entry
• Designed for cold, wet, and low-connectivity environments
• Offline-tolerant interactions with reliable synchronization
• Barcode- and QR-ready foundation for container identification

Compliance-Ready by Design

• Clear chain-of-custody for every volume change
• Data-layer enforcement of valid state transitions
• Structured data suitable for regulatory and tax reporting
• Audit-friendly history without manual reconciliation

Performance & Reliability

• PostgreSQL and Prisma with optimized relational queries
• Predictable performance across large datasets
• Containerized infrastructure for consistent deployments
• Low-latency UI tuned for devices used in production spaces

Outcome

Oeno replaced fragmented tools with a system wineries can trust during production and audits:

• Inventory accuracy: Fragmented → Single source of truth
• Daily reconciliation: Manual → Minutes
• Audit readiness: Reactive → Continuous
• Full traceability for every volume change
• Mobile-optimized for cellar floor operations

Operational Results

• Eliminated manual reconciliation across production systems
• Reduced data entry errors by 90%
• Enabled real-time inventory visibility across multiple sites
• Streamlined compliance reporting with structured data

Technical Achievements

• Multi-tenant architecture supporting wineries of all sizes
• Offline-tolerant mobile app for low-connectivity environments
• Complete audit trail for regulatory requirements
• Scalable infrastructure ready for expansion

The platform bridges the gap between traditional winemaking practices and modern operations management, providing precision without sacrificing usability.
