Migration of a national critical address correction tool —

a solution that had been unstable for 5 years,processing millions of calls

API, consumed by 30 internal applications (all La Poste divisions)

and external (including government applications).

Context:technical instability, accumulated legacy debt, no

mapping of existing uses, +150 stakeholders to align, objective of modernization without service disruption.

→ Zero service disruption on a nationally critical tool

→ Zero major incidents during the entire migration (3 years)

→ Zero functional loss

→ 30 applications migrated

→ Legacy decommissioned

→ New uses activated post-migration

Environment: distributed agile team France & Morocco (4 devs,

1 Tech Lead, 1 Scrum Master), API/DevOps, CI/CD, progressive deployments.

Structuring the management of global financial data in a

multi-ERP environment with high heterogeneity (40 ERPs, 6 geographical areas

Context:financial data not reconciled since September 2021,

persistent discrepancies between global Oracle extracts and local tracking,

accounting provisions as compensation due to lack of reliable data,

approximate quarterly reporting for the board.

→ Financial delta since Sept. 2021 resolved in 6 months

→ Approximate quarterly reporting → reliable weekly tracking

for the board

→ Reconciliation between global and local data reliable

→ Autonomous teams with trusted data

→ End of compensatory accounting provisions

Circana – formerly IRI France

10 years of supporting major clients (Heineken, France Boissons,

Eckes Granini) on assignments combining data analysis, commercial strategy

and marketing performance (Grocery, Out-of-Home, Sales Force).

What I did:

In-depth analysis of market data, dashboard design, diagnostics and identification of growth levers

Development and retention of client portfolios over long cycles, expansion of multi-channel scopes

Turnaround of struggling accounts: rebuilding relationships, improving service quality, strategic repositioning

Complete redesign of the data process and industrialization of studies for the France Boissons Out-of-Home account: end-to-end data chain audit, automation of integration (FTP, quality check, anomaly alerts), convincing two board-adjacent management teams to industrialize ad hoc studies — based on ROI analysis (20% of typologies = 80% of ad hoc revenue). Initiative carried out in complete autonomy, without a top-down mandate.

Management and skills development of junior and remote teams (including employees in India)

Results:

→ Client portfolio increased to €1M in managed revenue

→ Average contract duration: 2 years → 3-5 years per account

→ Revenue growth +20% over 5 years

→ Ad hoc revenue generated from dormant accounts: ~€150k/year on Heineken GD and €50-100k/year on Eckes Granini (zero when these accounts were taken over)

→ 50 studies/year for France Boissons with €100k ad hoc revenue: setup 4-5 days → reduced to 30 minutes automated

→ Quarterly penalties eliminated on critical data sold to Coca-Cola, Bacardi, Pepsico, Nestlé Waters

→ Database delivery time: D+12 → D+10

→ Junior consultants: Junior → Senior in 2 years instead of 3
