Production-ready Java backends, generated from a SQL schema.
Hexagonal architecture for global structure. Vertical slicing so every entity is a self-contained unit, not chaos across packages. A production-ready, 95–100% tested backend delivered in days, not months. Deploy as a vertical-sliced monolith or vertical-sliced microservices from the same schema. No lock-in.
- Java 25
- Spring Boot 4.1
- Hexagonal
- Vertical slicing
- OpenAPI
- 95–100% tests
Build it by hand
Two mid-level developers, from a blank page.
- 6–9 months before the structural layer is shippable
- Weeks on scaffolding & test plumbing, before one business rule
- 20–40% coverage under deadline; rarely measured systematically
- “Hexagonal” on paper: no vertical slices, layers shared across entities
- Dev + AI: different architecture every sprint
Generate it with AlveoForge
Guided end-to-end: same SQL, same output, every time.
- Days, not months: live Swagger preview before payment
- Hexagonal + vertical slicing: ports & adapters inside each entity slice
- Team on domain logic from day one, not scaffolding
- 95–100% test coverage: methods, lines & branches
- Large generated test suite, all green at handoff
Industrial patterns, from your DDL, not from prompts
Data model
- PostgreSQL DDL: schemas, FK, composite PK, UUID, ENUM
- Table inheritance (INHERITS / JOINED)
- Relations 1-n · n-n · 1-1 · join tables
- Multi-schema tables · identical names across schemas resolved
- Paginated lists · relation expansion (?expand) · single & bulk
Architecture & stores
- Hexagonal: domain isolated from database & HTTP
- Vertical slicing: one self-contained slice per entity (domain · application · infrastructure)
- Vertical-sliced monolith or microservices, same schema
- SQL + optional Mongo · Redis cache · transactional outbox
- Flyway or Liquibase (parity) · adopts your existing DB · DDL = source of truth
Quality assurance
- Unit & component tests per entity
- Database integration tests (SQL & Mongo)
- Full HTTP contract: success & failure (400 · 401 · 404 · 415)
- End-to-end tests with Docker (PostgreSQL + Mongo)
- Email flows verified in tests · HTML reports included
What you receive
Commercial
- Try before you buy: live Swagger; every endpoint testable pre-payment
- Private repo, code 100% yours · no vendor lock-in
- 30-day author support after handoff
- Regenerate when your SQL changes: deterministic output
Technical delivery
- 95–100% coverage report + HTML test reports with the delivery
- Runnable hexagonal, vertical-sliced monolith or microservices: same schema, your choice
- JWT auth · refresh tokens · email verification
- Setup & security documentation included
- Validated at 300+ tables scale · up to 1,000 → microservices
What stays with you
A production-ready backend, not a starter kit or Spring Initializr: hexagonal structure with a vertical slice per entity, runnable and deployable. Business rules and third-party integrations are yours. Row-level authorization stays with your team: authenticated CRUD by default, not per-row policy unless you extend it.
Guided delivery: schema review together → align modules & stores → live preview → private repo when you’re satisfied.
Your schema is confidential, used only to build your backend. NDA on request.
