Freelancer profile translated to English.
Back to original languageAbout Nicolas
Do you have a critical Java/Web application that has become difficult to evolve (technical debt, incidents, slowness, production risks)? I help SMEs regain control: stabilize the existing, secure deployments, and modernize progressively, without business disruption.
I am a Java Architect & Tech Lead (30 years of experience). My approach is pragmatic: we clarify priorities, reduce risk, and deliver value in stages. I don't come to "write code": I build a sustainable trajectory, with a high level of demand for quality, maintainability, and delivery.
What I offer (services):
IT Audit & Application Diagnosis
Architecture analysis, quality, performance, maintainability, risks. Deliverables: summary, prioritized recommendations, realistic action plan.
Architecture & Modernization Roadmap
Target architecture, reasoned decisions, POC if needed, strategy for coexistence of old/new IT systems.
Critical Application Development (Java/Spring/Web/API)
Design, implementation, integration, documentation, controlled deployment.
Delivery & Stabilization
Testing, CI/CD, observability, standards, continuous improvement: fewer incidents, more control, more reliable deliveries.
EVOLYA — progressive modernization of legacy Java IT systems
Step-by-step modernization, risk reduction, transfer of autonomy to teams. Objective: transform a legacy system into a sustainable asset.
Terms: full-time, remote or on-site (France).
If you want a clear roadmap rather than a risky project, I propose a scoping call to understand your context and define the initial priorities.
