01

One senior identity, three entry points

One foundation, three views depending on the challenge.

The site does not stack unrelated professions. It makes readable a profile connecting governance, business architecture, Product, business applications and quality.

Keeping decision-making, business rules, data and delivery aligned.

I step in when no single discipline can provide the answer: rules must be clarified, the model structured, the tool built, users supported and reliability demonstrated as the system changes.

03

In-depth case studies

Five transformations explained beyond the headline.

Each case sets out the context, challenge, contribution, deliverables and safeguards sought. Use the highly visible controls to expand or collapse the detail.

CASE 01Governance · Transformation · Data

Modernising portfolio steering without losing the governance logic

Evolving a repository and its reporting into a collaborative application while retaining the dependencies, indicators and traceability required for decision-making.

Portfolio
  • Multi-level repository
  • Filtered and global indicators
  • Campaigns & snapshots
Expand case study

Context

The system must consolidate heterogeneous project data, support several levels of reading and deliver reporting that remains consistent over time. A purely visual migration would risk reproducing screens without recovering the business behaviours that make them reliable.

Challenge

Connect reference data, campaigns, costs, milestones, risks, contacts, decisions and executive views while preserving the route from an aggregate indicator back to its source.

My contribution

  • Frame iso-functional behaviours and acceptable differences.
  • Analyse data structures, linking keys and reporting levels.
  • Design and test forms, filters, project views and portfolio views.
  • Test widgets and outputs, then document differences between test and production environments.
  • Prepare standalone publication and reporting that can be used outside the source database.

Deliverables

Relational modelPortfolio viewsReporting widgetsMulti-format outputsAcceptance scenarios

Safeguards sought

  • Traceability between synthesis and detail.
  • Consistent reading at project or portfolio level.
  • Known limits and differences made explicit before validation.

CASE 02Business architecture · Data · Product

Turning a complex assessment method into an actionable data architecture

Making a framework linking value, resources, costs, impacts, risks, assumptions and multi-year trajectories calculable and auditable.

Programme → Product → Assessment
  • Multi-entity model
  • 2019–2045 horizon
  • Controlled granularities
Expand case study

Context

Business objects have different granularities and time spans. A rule applied at assessment level instead of product level may produce a plausible but wrong result without triggering a technical error.

Challenge

Build a common foundation so that forms, calculations, workflows, visualisations and exports rely on the same entities, references and time boundaries.

My contribution

  • Identify Programme, Product and Assessment entities and detailed-data families.
  • Structure relationships, references, keys and metadata required by calculations and reporting.
  • Define time-boundary rules at the business level actually responsible for the data.
  • Connect T2 / HT2 costs, resources, FTEs, value, impacts, risks and assumptions.
  • Control aggregations, formulas and consistency between sources, screens and outputs.

Deliverables

Business architectureRelational modelTime rulesFormulas and selectorsWidgets and outputs

Safeguards sought

  • A business rule is calculated only at the correct level of granularity.
  • Multi-year trajectories remain consistent as periods change.
  • Reporting can be traced back to source data.

CASE 03Grist · Workflows · Industrialisation

Industrialising a Grist business application beyond a shared spreadsheet

Combining relational modelling, widgets, APIs and controls to secure sensitive operations on linked business objects.

Low-code + pro-code
  • HTML / JS widgets
  • Grist API
  • Multi-table lifecycles
Expand case study

Context

Grist provides a relational and collaborative foundation, but complex business uses require dedicated behaviours: duplication, history, campaigns, recoverable deletion, exports, logging and confirmations.

Challenge

Automate operations spanning several tables, references, formulas and permissions without hiding failures or creating false confidence in success.

My contribution

  • Design dedicated widgets where native functions do not cover the need.
  • Separate the operation, consistency control and final validation.
  • Preview effects, require explicit confirmations and log each step.
  • Compare before/after and control data by type.
  • Document components, reuse tested solutions and harmonise corrections.

Deliverables

Lifecycle widgetsSupervised duplicationHistory managementRecoverable deletionConsistency reports

Safeguards sought

  • Preserve references, history and formulas.
  • Make operations recoverable and explainable.
  • Expose residual limits rather than hide them.

CASE 04Authorisation · Diagnosis · Functional security

Making dynamic permissions understandable and testable

Connecting identity, role, business object, scope and period without confusing the authorisation model with its application mechanism.

Identity + role + context
  • Grist ACLs
  • RBAC / ABAC
  • Federated-identity context
Expand case study

Context

A hidden screen does not explain an access decision. In a multi-user application, permissions may depend on identity, role, ministry, product, project, year or status.

Challenge

Avoid permissions that are too broad, inconsistent redaction and fragile dependencies on poorly normalised identities, while keeping rules readable and diagnosable.

My contribution

  • Formalise the roles and contextual attributes used in the decision.
  • Diagnose Grist ACL rules and their functional dependencies.
  • Normalise and consolidate identity attributes used as matching keys.
  • Test read, write and visibility behaviours by profile and period.
  • Use RBAC and ABAC to explain the policy without confusing them with ACLs that apply it.

Deliverables

ACL rulesSharing mechanismsConsolidated attributesDiagnostic logsEducational simulator

Safeguards sought

  • An access decision can be explained.
  • Rules remain close to the business context.
  • Formal security claims are not overstated.

CASE 05Quality · Auditability · AI-assisted

Establishing a discipline of evidence and regression control

Returning to source data, comparing expected and observed behaviour, and refusing a local fix that merely moves the problem elsewhere.

Expected ↔ Observed
  • Log analysis
  • Before / after comparison
  • Human validation
Expand case study

Context

In an interdependent model, a result may look correct even when the wrong source, aggregation, period or rounding rule is being used. A plausible answer is therefore not enough.

Challenge

Identify the real cause of a behaviour, correct it at the right level, then verify that the change has not damaged other formulas, widgets, outputs or access rules.

My contribution

  • Analyse data, formulas, code, logs and dependencies together.
  • Reconstruct the chain source → transformation → aggregation → display.
  • Compare anonymised before/after exports and systematically search for side effects.
  • Separate calculation precision from display rounding.
  • Use AI to accelerate exploration and prototyping, with criticism, tests and human validation.

Deliverables

Structured diagnosticsComparison datasetsRegression controlsDocumented codeDecision notes

Safeguards sought

  • Correct the cause rather than the symptom.
  • Protect overall system consistency.
  • Retain a trace of assumptions, limits and validations.

Interactive demonstration

Explaining an authorisation decision, not merely hiding a screen.

This educational demonstrator was created for the portfolio. It illustrates the concepts and does not reproduce any internal access rule.

What the demo shows

Three concepts, three functions.

Select a role, product and year. The system then exposes the reasoning leading to read, write or export access.

  1. RBAC sets the baseline associated with the role.
  2. ABAC refines the decision based on context.
  3. ACL applies the rules in the application.

Method

A plausible answer is not yet evidence.

I move an idea towards a solution whose choices can be explained, behaviour observed and limits verified.

01

Understand

Clarify the expected outcome, collect rules, data, code and logs, then model dependencies and the criteria that must remain true.

02

Build

Prototype the minimum useful solution, compare options and progressively integrate it into the real system.

03

Prove

Compare expected with observed behaviour, test edge cases, verify permissions, calculations and regression before handover.

AI as a problem-solving partner

An exacting, tool-assisted dialogue — not delegation.

I use AI to accelerate exploration, prototyping, code and log analysis, anonymised-data analysis and documentation. I provide context, challenge assumptions, compare proposals with the real system and remain responsible for validation.

A complex problem to understand, transform or strengthen?

I focus on senior roles connecting decision-making, business needs, data and delivery across business architecture, digital transformation and Portfolio / PMO. Depending on the context, these responsibilities may take the form of a permanent role, an independent consulting engagement or a transformation assignment, across France and internationally.
