Software Modernization & Technical Consulting

Improve existing software without unnecessarily rebuilding everything.

Long-lived applications contain valuable domain knowledge — and often technical debt that slows down every change. We analyze your codebase, identify the most effective levers and modernize step by step: without big-bang risk and without disrupting day-to-day operations.

Free initial consultation

Typical starting points

  • Every change takes longer than it should and introduces unexpected bugs.
  • The application runs on outdated frameworks or untyped JavaScript.
  • There are hardly any automated tests, so every release is a risk.
  • Several teams work on one frontend monolith and keep blocking each other.

What we deliver

  • Architecture reviews & code audits

    A thorough analysis of structure, dependencies, quality and risk — with prioritized, actionable recommendations.

  • Frontend & mobile modernization

    Incremental migration of legacy frontends to React, moving from JavaScript to TypeScript and modernizing existing React Native apps.

  • Performance optimization

    Analyzing and improving load times, rendering performance and bundle sizes.

  • Modularization & microfrontends

    Restructuring frontend monoliths, monorepos with Nx or Turborepo, and a level-headed evaluation of whether microfrontends make sense.

  • Testing strategy & quality standards

    A sensible test pyramid with Jest, Playwright, Cypress and MSW, plus clear standards for your team.

  • Development workflow & API architecture

    Improving CI/CD, code review culture and development workflows, plus advice on API design and interfaces.

Our approach

  1. 1

    Assessment

    We build a solid understanding of your codebase, architecture, processes and the biggest pain points.

  2. 2

    Prioritized roadmap

    Instead of a long list of flaws, you get concrete measures ranked by impact and effort.

  3. 3

    Incremental delivery

    Modernization while the system stays in use — module by module, backed by tests and with verifiable milestones.

Questions about this service

Rebuild or modernize?

In most cases, incremental modernization is more economical and less risky than a complete rebuild. A review shows which path makes sense in your situation.

How does a code audit work?

After a short introduction from your team, we analyze the codebase, architecture, tests and build process. You receive a written report with prioritized recommendations, which we walk through together.
