Work & experience

Complex systems. Tangible results.

Since 1991, I have designed architectures, recovered troubled programmes and built products. European institutions, telecommunications, Flutter applications and now AI: these are the engagements behind that experience.

Institutions & telecommunications

Architecture tested in the real world.

Connecting systems, coordinating teams, unblocking delivery and restoring service: four programmes illustrate the breadth of my responsibilities.

European Commission · DG OLAF

Three generations of anti-fraud systems.

Senior architect · Project manager · Business analyst · Auditor

Several engagements between 1994 and 2021

15+critical applications

3 billion+documents in the system

AFIS enables European administrations to exchange and use information to fight fraud. I contributed to three generations of the system, from its foundations to applications and large-scale data processing.

My contribution

Designed the shared service-oriented architecture and framework: state management, authorisations and application integration, working with the Commission and project leads.
Architected real-time processing across more than 3 billion documents using MongoDB and Elasticsearch, with anonymisation aligned with European Data Protection Supervisor criteria.
Analysed requirements with OLAF owners and Member State representatives; managed budgets, teams, development and testing; audited the system and reorganised testing practices.

Outcome & scope

Work connecting architecture, data protection and delivery: the SOA generation encompasses more than 15 critical applications and over 10,000 users.

Commission engagements through ATOS, CSB and Unisys. Figures describe the AFIS scope, delivered with the programme teams.

Belgacom / Proximus · OMS / NPS

Connect ordering to service activation.

Technical & functional architect · Test manager

2000–2006

~20applications in end-to-end testing

A major transformation of ordering, provisioning and billing systems. As architect of the NPS layer, I connected business applications, middleware and existing core systems, reporting directly to the CIO.

My contribution

Designed the NPS layer from ordering to technical service activation, across Java, C/C++, Tuxedo and mainframe systems.
Conducted J2EE architecture reviews and code audits; coordinated technical work with Infosys, including on-site engagements in India.
Defined integration and acceptance methods, environments and test plans; organised end-to-end load and stress testing across around twenty applications.

Outcome & scope

The NPS layer went into production meeting performance, load, scalability and robustness requirements. End-to-end testing enabled substantial corrections before go-live.

Architecture responsibility for the NPS layer within the OMS / NPS programme.

European Commission · DG TAXUD · Transit / NCTS

Get a stalled programme moving again.

Auditor · Technical centre manager

1999–2000

7 / 7supported Member States certified

The customs transit programme had stalled. I was brought in to diagnose the situation, rebuild its functional and logical architecture, and reorganise technical delivery.

My contribution

Audited the situation, reorganised teams and workflows, and clarified the architecture and validation practices.
Coordinated certification testing between national administrations and the European Commission.
Specified and delivered a web tool for real-time test monitoring and information sharing.

Outcome & scope

All seven supported Member States achieved certification: a concrete result within a programme whose scope covered 59 countries.

Engagement through Siemens for DG TAXUD.

European Commission · DG TAXUD · ITSM

Restore service commitments.

Service level manager · PMO lead

2008–2013

3companies in the managed consortium

I was appointed when the prime contractor was breaching service commitments and facing significant penalties. The task was to restore service quality and make contract management dependable.

My contribution

Restored service levels, reviewed subcontractor agreements and introduced a continuous service improvement policy.
Led the project management office for a three-company consortium across Europe: priorities, activity forecasts, costs, metrics and reporting.
Automated information exchange and complex reporting; reviewed the design of the new service management tool.

Outcome & scope

Service levels were restored and pending penalties removed, supported by structured operational and financial management across the consortium.

Engagement through Unisys for DG TAXUD.

Series in preparation

From a concrete case to a governance engagement.

Each article will start with an i-Discover situation to explain the work involved, the decisions to make and the deliverables an organisation can use.
