Why “Solark”?

Solution Architect

The name says what the job is. A solution architect starts from the real need, designs a coherent answer — infrastructure, cloud, data, operations, security — and makes sure it remains viable once delivered.

01 — Services

Three audiences, one craft

Whether you need to choose a solution, procure it by the rules or sell it, the question is the same: which answer will hold up over time, technically and economically?

Businesses and organisations

An outside architect's view to make informed decisions before committing budget.

  • Target architecture: private, hybrid or sovereign cloud
  • Legacy environment modernisation — or exit — programmes
  • Scoping AI projects, on-premises or in a trusted cloud
  • Roadmap, budget estimate, vendor selection
Modernising existing systems

Public bodies

Municipalities, public social welfare centres, inter-municipal bodies and public agencies: support for contracting authorities on IT, telecoms, cloud and AI projects.

  • Needs and current-state assessment
  • Tender specifications: technical section or the full document
  • Running the procurement procedure through to contract award
  • Monitoring contractors during implementation
How I work

IT integrators and software vendors

Turning a technology into an offering you can sell, deliver and defend in front of the client.

  • Offering and managed-service design: scope, roles and responsibilities, cost model
  • Business plans for new offerings and innovation processes
  • Presales, tender responses, go / no-go decisions
  • Vendor partnerships and business development
Structuring innovation

02 — Legacy & modernity

From critical existing systems to agentic AI

More than twenty years running, integrating and selling critical systems, from long-established platforms to hybrid clouds. Since 2024, agentic AI has changed the game: what seemed frozen can be documented, rewritten, connected and automated — as long as a human remains accountable at every step.

A

Understand what exists

AI-assisted reverse documentation of applications and infrastructure: RPG or COBOL code, scripts, configurations, business rules.

B

Modernise step by step

Rewrite, migrate or wrap: keep what works, replace what holds you back, without a big bang.

C

Orchestrate and automate

Agent chains to deploy, operate and report: speed, restart capability and traceability, from infrastructure to applications.

D

Steer without waiting for migration

Connect data from existing systems (ERP, CRM, mailboxes) to make decisions before everything is merged: merger, consolidation or transition.

Run a programme, not a project

Compared scenarios, business plan, skills and hiring plan, governance and milestones: I initiated and led a modernisation programme for critical legacy environments within an IT integrator, through to executive approval.

03 — Public sector

Supporting public bodies, from assessment to contract award

A public IT project is often won or lost in the tender specifications. Solark helps contracting authorities express the right need, choose the appropriate procedure under Belgian public procurement rules and compare bids on solid grounds — then stays at their side during implementation. Step by step or end to end.

  1. 01

    Assess

    Analysis of the current situation, departmental needs and budget or grant constraints.

  2. 02

    Draft

    Tender specifications: technical requirements, selection and award criteria, bill of quantities.

  3. 03

    Award

    Choice of procedure, bidder questions, negotiation, bid evaluation and award recommendation.

  4. 04

    Support

    Coordination and monitoring of contractors during installation, through to acceptance.

Example assignment

Digital transformation of a Walloon municipality

Project supported by the Walloon Region (“Tax on Pylons” call for projects): fibre-optic links between municipal sites, replacement of physical servers with a cloud solution and a move to IP telephony.

Assessment Tender specifications Procedures and operator selection Installation follow-up

Both sides of the table

Since 2010, I have helped draft or respond to dozens of public tender specifications: hospitals, municipalities, public agencies.

I know what makes bids comparable and what derails a tender. I put this bidder's experience at the service of contracting authorities.

04 — Innovation

Structuring innovation, from idea to market

As co-founder of an Innovation & Technology Office within a Belgian-Luxembourg IT group, I designed the governance model that guides every new solution from idea to market launch. It is a method I can put in place for you.

  • Stage-gate process, with exit criteria and standard deliverables at each gate
  • Decision bodies and a steering rhythm with executive management
  • Steering non-billable R&D time towards strategic projects
  • Business plans and investment cases for new offerings
  • Organisation and skills for the agentic era: which profiles to hire, train and develop

AI: from talk to practice

Having helped launch the first AI initiatives of an IT group, I work with executives and IT decision-makers, from SMEs to the public sector, to turn AI into concrete, deployable use cases.

Public procurement for ICT

Needs before technology

The solution follows usage, constraints and budget — never a preference for a product.

Security and operations by design

Backup, continuity, security and running costs are part of the architecture, not an add-on at the end of the project.

Reusable deliverables

Every step produces a document you can review, challenge and reuse without me.

AI automates, a human stays accountable

Guardrails designed upfront and accountable decisions: automation can go far, responsibility stays human.

06 — Career

At the interface, from the start

Systems engineer, presales, manager, business developer, then solution architect and innovation programme lead: my career has been built at the junction between vendors, integrators and clients, between sales and technical teams, between Belgium and Luxembourg.

More than ten years of managing presales and back-office teams taught me that a good solution also depends on the people who carry it.
