Freelancer profile translated to English.

Description

I support companies in the design, modernization, and integration of complex application systems.

My core expertise: application architecture, IT integration, ERP, MES/MOM, legacy, application security, CI/CD, Low-Code/No-Code, BPMN orchestration, and Best of Breed architectures.

I work with heterogeneous IT systems: legacy applications, ERP, PLM, MES/MOM, WMS, business tools, multiple APIs, poorly documented flows, traceability requirements, security, or industrialization difficulties.

I know how to support Best of Breed architectures: select the best solutions per functional area, clarify the role of each application, define master data, scope flows, APIs, interoperability, traceability, security, and operations.

I also work on orchestration via BPMN to formalize sequences, responsibilities between actors and systems, and make processes readable and auditable.

I use Low-Code/No-Code, particularly n8n, Zapier, or Make, to prototype workflows, connect SaaS applications, APIs, or internal systems, and automate business processes when a lightweight solution is preferable to full development.

Typical missions:

application architecture audit;
flow and dependency mapping;
target architecture design HLD/LLD;
API and application integration scoping;
Best of Breed architecture support;
BPMN modeling and orchestration;
Low-Code/No-Code automation;
legacy system modernization;
Java/Spring Boot design;
OIDC, Keycloak, OAuth2, API security hardening;
GitLab CI/CD, Docker, k3s support;
support for teams and technical decision-makers.

I do not position myself as a pure DevOps or an exclusive cybersecurity expert: my value is to connect application, business, integration, orchestration, automation, security, and operations to produce a realistic and maintainable architecture.
