Budget Triage
Enterprise Architecture Exploration
Overview
Personal finance management system built with enterprise-grade architecture patterns. Intentionally over-engineered to explore modern governance frameworks, observability patterns, and deterministic ML extraction pipelines.
Achieved F1=1.000 extraction quality on ground-truth datasets through agent-assisted annotation and deterministic synthetic document generation.
Technical Stack
Runtime & Core
- Bun (modern TypeScript runtime)
- Express + Hono (dual API framework exploration)
- PostgreSQL with type-safe schema generation (Kanel)
- ts-rest for end-to-end type contracts
Infrastructure & Security
- Infisical (self-hosted secrets management)
- Machine identity patterns for automated access
- Docker containerization
- OpenTelemetry instrumentation throughout
Governance Framework
- ADR-020 (Architecture Decision Records)
- Runtime/config/toolchain compliance verification
- Script governance rules
- Cross-surface validation
- Evidence-based logging
Key Patterns Explored
Architecture Decision Records (ADR-020)
Formal governance framework ensuring runtime, configuration, and toolchain compliance. 18/19 CI Quality Gates passing.
Intelligent Document Processing
Architecting resilient VLM/OCR pipelines with strict quality baselines (F1=1.000), agent-assisted annotation, and synthetic ground truth.
High-Volume Test Engineering
Over 7,700+ tests (7,082 backend, 703 frontend, 664 integration) ensuring deterministic performance across complex extraction operations.
Why This Matters
Governance at Scale
ADR frameworks and policy-based development are crucial for large teams. Learning the patterns in a controlled environment.
Security Best Practices
Secrets management, machine identity, audit logging—production security patterns in practice.
Modern TypeScript Ecosystem
Bun, modern frameworks, type-safe patterns. Staying current with evolving JavaScript/TypeScript landscape.
Observability Mindset
Building systems that are observable from day one. OpenTelemetry, structured logging, traces.
Development Philosophy
This project is intentionally over-engineered for its scope. The goal isn't to ship the perfect budgeting app—it's to deeply understand enterprise patterns that become essential at scale.
Would you use ADR governance for a personal project in production? Probably not. But understanding ADR frameworks by implementing them teaches patterns applicable to large codebases, distributed teams, and regulated environments.
Projects as learning experiences—using practical applications to explore theoretical and architectural concepts.
