Rescue & Scale
Code Refactoring & Modernization
Clean up technical debt, modernize legacy code, and improve maintainability. We restructure messy codebases, establish best practices, and make your codebase a joy to work with. Refactoring with change control: tests first, safe rollouts, and maintainability gains (EU overlap (CET/CEST-friendly)).

Features
What we deliver
Legacy Migration
Migrate from outdated frameworks (AngularJS, jQuery, Rails) to modern stacks (React, Next.js, Node.js).
TypeScript Migration
Add type safety to JavaScript codebases. Catch bugs at compile time and improve developer experience.
Architecture Improvements
Break monoliths into microservices or modular architecture. Improve code organization and maintainability.
Test Coverage
Add comprehensive test suites with unit, integration, and end-to-end tests for confidence in changes.
Error Handling
Implement proper error handling, logging, and monitoring for production-ready applications.
Documentation
Code documentation, architecture diagrams, and developer guides for team knowledge sharing.

FAQ
Frequently asked questions
We write tests before refactoring, refactor incrementally, and test after each change. We maintain feature parity and use staging environments.
Yes. We refactor incrementally while building new features, improving code structure as we work to reduce risk and allow continuous delivery.
We write tests for critical paths first, use characterization tests to understand existing behavior, then improve code safely and incrementally.
Standards for code style (ESLint, Prettier), architecture patterns, testing practices, documentation, and Git workflows tailored to your team.

Delivery considerations for your region
Data and risk discovery (Germany)
Privacy, security, residency, and regulatory requirements differ by workflow. We document the applicable data flows, roles, retention needs, and control owners before recommending an architecture.
The resulting proposal lists the controls and evidence that are actually in scope. It is not a generic compliance, certification, or legal-assurance promise.
- Map data sources, destinations, roles, and sensitive fields
- Record access, retention, logging, and deletion requirements
- Identify required security or procurement evidence before contracting
- Use an NDA or DPA only when the parties mutually execute it
Working model (Germany)
Exact live-overlap hours, response expectations, meeting windows, and escalation contacts are confirmed in the proposal for each engagement.
Written decisions, scoped milestones, and asynchronous updates reduce unnecessary meetings without implying an unagreed service level.
- Proposal-specific overlap and meeting windows
- Named owners for decisions and blockers
- Written scope, assumptions, and change decisions
- Milestone cadence agreed before kickoff
Commercial setup (Germany)
The contracting entity, proposal currency, invoicing cadence, payment terms, intellectual-property terms, and required vendor documents are agreed before work begins.
The Opportunity Sprint can establish the evidence needed to scope a production pilot; it does not pre-commit either party to a rollout.
- Contracting entity and currency confirmed in writing
- Milestones and acceptance criteria defined in the proposal
- Vendor-document requirements identified before signature
- Scope changes require an explicit written decision
Delivery controls (Germany)
Testing, observability, release, security, and handover controls are selected for the actual system risk rather than promised as a generic bundle.
Acceptance measures and production responsibilities are recorded before implementation so both teams know what evidence will support release.
- Risk-based testing and acceptance measures
- Release, rollback, and observability responsibilities
- Security controls tied to the agreed threat model
- Handover artifacts defined in the signed scope
