§ MODULES

What I work on in existing systems

Each building block can be commissioned on its own. After every step you decide whether to continue.
Common starting point
Code auditArchitecture, security, dependencies, and test coverage, with a prioritised backlog and cost range.
Common starting point
Test automationUnit to end-to-end tests with Playwright, Selenium, or Ranorex, so changes stop being scary.
Common starting point
Build and deploymentReproducible builds, automated tests, and deployments instead of manual steps on Friday evening.
After the audit
StabilisationFix critical bugs, set up monitoring, and eliminate the most frequent outages.
After the audit
Stepwise replatformingMove old Java EE or PHP parts module by module to Spring Boot or Node.js, without a big bang.
After the audit
Internal toolsReplace Excel and siloed solutions with one web application connected to your databases.
After the audit
Handover to the teamDocumentation, pair programming, and architecture decisions so your team can carry on independently.
After the audit
Online paymentsConnect Stripe, PayPal, or Mollie to existing systems, with clean webhooks.
§ PROCESS

How we work together

Four phases, each commissioned separately.
  1. 01

    Audit and roadmap

    Codebase analysis, risks, and priorities. Result: a report with backlog and fixed-price range.
  2. 02

    Stabilisation

    Add tests, fix critical bugs, secure deployment. Small, but noticeable.
  3. 03

    Modernisation

    Renew modules where the benefit justifies the effort. The system keeps running.
  4. 04

    Handover

    Your team takes over with documentation and joint sessions, or I keep looking after it.
