Technical analysis for a monolith-to-microservices migration, connecting business, development and testing.
Since May 2026, I have worked as a Senior Technical Analyst for a Belgian federal administration in Brussels. The assignment covers analysis for a monolith-to-microservices migration across multiple teams.
I translate existing business rules into implementable requirements, write specifications and design interface contracts with development and testing teams.

Specifications and OpenAPI
Decomposing the monolith requires explicit target workflows, exchanged data and responsibilities for each service.
Analysis connects existing behaviours to target needs to produce actionable functional and technical specifications.
OpenAPI contracts specify schemas, failure cases, response codes and responsibilities for each endpoint. They are validated with development teams.
Coordination across business, development and testing maintains a link between original rules, requirements and validation.
The assignment remains ongoing in September 2026. This reference concerns technical analysis and interface design; it is not an AI assignment.
Let's talk about your product, platform, or operational workflow and see how I can help shape and build it.
