Backend-focused developer building production-style systems with TypeScript, PostgreSQL, and clean architecture.
I focus on systems that need clear data models, transactional integrity, tenant isolation, and predictable behavior.
- PostgreSQL schema design, constraints, indexing, and transactions
- TypeScript backend development
- Clean / hexagonal architecture
- Multi-tenant application design
- Idempotent API workflows
- Deterministic business logic
- Security-first system design
A private tool for capturing client discovery calls, manual notes, transcript segments, requirements, and structured call history.
Focus areas:
- Tenant-scoped call records
- Manual and transcript-based note capture
- Deterministic sequence numbering
- Structured requirement extraction
- Production-style frontend/backend separation
A reusable lead capture and estimate engine for service businesses.
Focus areas:
- Tenant-specific configuration
- PostgreSQL-backed pricing rules
- Embeddable widget flow
- Lead persistence
- API-driven estimate generation
A transactional income and expense tracking system focused on correctness.
Focus areas:
- Schema-first design
- Database constraints
- Reporting logic
- Balance calculation
- Data integrity
- Schema first
- Explicit domain modeling
- Database constraints over application assumptions
- Transactions where correctness matters
- Idempotent operations where applicable
- Clear separation between domain, application, infrastructure, and presentation layers
- Explicit behavior over hidden magic
Building slowly. Building correctly.
