Modernize your legacy system. Without starting over.

Grown over years, touched by dozens of developers, documented by no one. Jardis gives your PHP monolith the DDD architecture it should have had from day one. Step by step, without a rewrite.

Grown without a plan. Now you pay the price.

Legacy systems don't die suddenly. They get slower, riskier, and more expensive until every change becomes a gamble.

Every change can break everything

No clear boundaries, no layers, no contracts. A fix in checkout breaks invoicing because both modules share the same classes and tables. Regressions are the norm, not the exception.

Business logic is everywhere

Validations in controllers, calculations in views, business rules in SQL queries. Nobody knows where the truth lives anymore. Duplicated logic, contradictory results, and no safe place to start refactoring.

New developers need months to ramp up

No onboarding document can explain what grew organically over 10 years. Every new developer needs months before they can work productively without breaking things.

How Jardis Solves Legacy Modernization.

Jardis doesn't replace your code. It gives your system the structure it never had.

DOMAIN EXTRACTION

Identify and isolate domains

Jardis generates standalone Bounded Contexts from your domain analysis. Orders, customers, billing: each domain becomes a clearly separated package with its own entities, aggregates, and events. The new structure lives alongside your legacy code.

INCREMENTAL MIGRATION

No big-bang rewrite, controlled restructuring

You migrate one domain at a time. Jardis generates the target state for each Bounded Context. Your team moves business logic from the monolith into the new architecture step by step. No downtime, no risk.

ARCHITECTURE STANDARD

Consistent structure for every new domain

Every generated Bounded Context follows the same hexagonal architecture. Entities, commands, queries, events, API contracts, and the repository pipeline. Consistent patterns instead of individual interpretation per developer.

Why Teams with Legacy Systems Choose Jardis.

From an overgrown monolith to maintainable architecture. Without throwing everything away.

> Clear Boundaries

Domains Instead of Spaghetti

Each business domain becomes a standalone package. Orders can no longer reach into customer tables. Dependencies become explicit instead of implicit.

> Velocity

New Features in Hours Instead of Weeks

New Bounded Context for an additional domain? Define the schema, start the builder, production-ready structure in minutes. No manual infrastructure setup needed.

> Risk Reduction

Changes Without Fear

Clear domain boundaries mean: a change in billing cannot break checkout. Contracts between Bounded Contexts make dependencies visible and manageable.

Frequently Asked Questions

Answers to the most important questions about Jardis for legacy modernization.

No. Jardis is built for incremental migration. You identify a domain, generate the Bounded Context, and migrate the business logic. The rest of the system keeps running as before.
