Legacy Systems Risk Advisor

Your most critical system is also your biggest blind spot.

If your company runs on software built more than 10 years ago — ERP, production management, logistics, finance — you have a risk that's invisible until it isn't.

I help CTOs and IT Directors in mid-market companies understand exactly where that risk lives, what it costs if it materializes, and how to reduce it without a full rewrite.

For more than 30 years, I have built, maintained, and modernized business-critical systems. Today I focus that experience on legacy platforms that are hard to replace, hard to staff, and too important to ignore.

The Problem

Legacy systems don't fail gradually. They fail all at once.

Most companies know their core systems are aging. Few know exactly how fragile they are. The person who built the system left years ago. The documentation is incomplete. The vendor is end-of-life. And the board is asking about AI.

I work with companies that recognize these signals:

Critical business systems built before 2010, still running in production
Key-person dependency — one engineer who "knows how it works"
Vendor end-of-life approaching with no migration plan
Pressure to add AI capabilities without replacing core infrastructure
Maintenance costs growing faster than the system's business value

Services

Three ways to reduce legacy system risk.

Legacy Risk Assessment

A 20–30 page technical report that maps your critical dependencies, scores risk by component, and gives you a prioritized modernization roadmap. The document your CTO needs to present to the board.

From €3,500 · 2–3 weeks

Modernization Sprint

Take the most critical module — billing, order management, ERP integration — and modernize it without stopping production. API layer, refactoring, data migration, handover to your team.

From €15,000 · 4–10 weeks

AI Integration Layer

Add AI capabilities — document classification, demand forecasting, internal assistant — on top of your existing systems. No replacement needed. Proof of concept in 2 weeks.

From €8,000 · 6–8 weeks

Background

Senior technical judgment for systems that cannot afford mistakes.

I am not approaching legacy environments as a generic modernization consultant. My background comes from decades spent inside the realities these companies still operate every day: long-lived codebases, undocumented dependencies, operational constraints, and systems that keep revenue moving.

That matters because legacy risk is rarely just a code problem. It is a continuity problem, an ownership problem, and eventually a board-level cost problem. The job is not to propose a fashionable rewrite. The job is to identify what is truly fragile, what must be stabilized first, and what can be modernized without disrupting the business.

How it works

From risk assessment to resolution.

45-minute technical call We map your current system landscape, identify the critical components, and determine if there's a real risk worth addressing. No cost, no commitment.
Risk Assessment report I deliver a detailed analysis of your system dependencies, failure scenarios, and a prioritized action plan. This becomes the foundation for any future work.
Implementation (if needed) Based on the assessment, we can proceed with targeted modernization or AI integration — in phased sprints with measurable results at each stage.
