## Identity

Thomas Nys is an independent fractional data architect based in Hamme, East Flanders, Belgium. He works in English and Dutch and can work with French-speaking organizations. His work combines data architecture, hands-on engineering, technical leadership, and cross-team decision-making.

Thomas designs data systems that actually get built. He starts from the business problem, current constraints, ownership, and adoption before recommending a platform or tool.

Canonical profile: https://thomasnys.com/about/

## Client fit

### Primary segment

Growing companies with roughly 25-80 employees, 3-12 engineers, and no full-time data leader. The usual buyer is a CTO, technical founder, CEO, or VP Engineering. The company may be setting up its first serious data capability or dealing with unreliable pipelines, unclear ownership, slow reporting, or a platform that no longer fits its growth stage.

### Secondary segment

Companies with roughly 80-250 employees, an existing Head of Data or data-platform lead, and a larger data team. Thomas joins as a senior architecture partner during a migration, replatforming, or difficult platform decision.

### Poor fit

- Pre-product companies with little data and no architecture problem yet.
- Companies seeking cheap staff augmentation or a full-time delivery role.
- Buyers who want a strategy document without implementation or ownership.
- A leadership retainer layered over an existing Head of Data.

## Offer ladder

### Platform Review

Canonical page: https://thomasnys.com/services/platform-review/

A fixed-scope assessment before a major platform decision or delivery commitment. Thomas reviews architecture, data flows, pipelines, cost, reliability, ownership, governance, and tooling. The client receives a written assessment, risk view, and prioritized action plan. Follow-on delivery is optional.

### Fractional Data Architect

Canonical page: https://thomasnys.com/services/fractional-data-architect/

Ongoing senior architecture leadership for a company that needs the function before it needs a full-time hire. The work can include architecture decisions, hands-on engineering, code review, standards, team mentoring, stakeholder alignment, and roadmap ownership. The intended exit is a team that can operate without Thomas.

### Architecture Advisory

Canonical page: https://thomasnys.com/services/architecture-advisory/

Focused senior input for a specific architecture, migration, vendor, or platform decision. The work may produce a decision brief, risks, alternatives, and a clear recommendation with the conditions that would change it.

### Secondary partner work

Technical pre-sales, practitioner content, and junior-consultant coaching are available for data-product companies, agencies, and consultancies. They are separate from the core offer ladder.
