Application Modernization

Overview

Older applications often hold years of valuable business logic, but become slow, insecure or impossible to change. SubinLabs modernises them incrementally: stabilising first, then refactoring, upgrading and redesigning in steps that keep the system running.

The result is a codebase your team can work with again, on supported technology, with security and performance brought up to current standards.

Problems this solves

• Applications on unsupported language or framework versions
• Security vulnerabilities and outdated dependencies
• Slow pages and growing infrastructure costs
• Fear of changing code that nobody fully understands

Capabilities

• Codebase and architecture assessment
• Framework, language and dependency upgrades
• Incremental refactoring with test coverage
• Performance and security remediation
• Interface redesign and responsive conversion
• Data and infrastructure migration

Typical use cases

• Upgrading a business-critical PHP application to a supported version
• Replacing a dated interface while keeping proven backend logic
• Breaking a monolith into clearer modules ahead of new features

Delivery approach

1. Assess

   Audit code, dependencies, security and performance to find the real risks.

2. Stabilise

   Add tests and monitoring around the most critical paths.

3. Modernise in steps

   Upgrade and refactor incrementally, releasing frequently.

4. Hand back control

   Document the new architecture and support your team.
