Description

Functional architecture and API design consultant, with 7 years of experience in complex IT environments (insurance, banking, software publishers).

I support end clients in analyzing business needs, IT impact assessments, and designing application solutions, in close collaboration with business teams, Product Owners, solution architects, and technical teams.

My expertise focuses particularly on REST API design (OpenAPI / Swagger), IT integration, and micro-services oriented architectures, with a strong emphasis on API governance and interface contract quality.

I have worked in large enterprise contexts, within scaled agile frameworks, ensuring the production and maintenance of design documentation (technical maps, flow diagrams, specifications, Swagger).

Thanks to a background in development and QA, I propose realistic solutions, aligned with the technical and operational constraints of the teams.

Types of missions sought: IT solution scoping and design, business analyst / functional / application architecture, API design and governance, IT integration.
