Mission — Technical architecture reinforcement & global DevSecOps transformation

➜ Objective
↳ Strengthen the technical architecture team on existing systems and lead a global IT modernization initiative: security, resilience, scalability, and DevSecOps industrialization.

➜ Key Achievements
◉Comprehensive IT System Audit(datacenter, virtualization, storage, network, applications, middleware) to identify SPOFs and define a scalable target architecture (x25).

◉ **Refactoring of Critical Components**: new SPOF-free ActiveMQ architecture, storage rationalization (NetApp, SAN), and network hardening (FortiGate, VPN, PRA/PCA).

◉Implementation of CDN/WAF Solutionsand strengthening of application security (DDoS protection, OWASP Top 10, secure APIs).

◉ **Kubernetes Design and Deployment**: cost analysis, application migration, complete CI/CD (Jenkins, Helm, Harbor).

◉Automation with Ansibleand writing architecture documents (DAT, DEX).

◉Deployment of a Global Observability Platform(monitoring, logs, alerting) covering 200 VMs, 2 Kubernetes clusters, and 7 international sites.

◉ Involvement across the entire cycle: POC → target architecture → industrialization → production.

➜ Results / Added Value
✔︎ More resilient, secure, and scalable IT system, capable of handling 25x increased load.
✔︎ Industrialized CI/CD pipeline and application deployments.
✔︎ Unified visibility and supervision across an international multi-datacenter environment.

➜ Technical Environment
VMware, Kubernetes, Jenkins, AWX/Ansible, Helm, Harbor, ActiveMQ, PostgreSQL, MySQL, Cassandra, MongoDB, Redis, SAP, NetApp, FortiGate, VPN, CDN/WAF, PRA/PCA, CI/CD, Observability (ELK, Prometheus/Grafana).

Mission — Functional & Technical Architecture for New Software Integration

➜ Objective
↳ Translate strategic client needs into a clear target architecture, integrated with the existing environment (Cloud + Hyper-V on-prem) and framed by comprehensive specifications.

➜ Key Achievements
◉ Business needs analysis and formalization → domain models, use cases, and prioritization.
◉ Mapping of the existing environment (software, APIs, hosting) and definition of the target integration.
◉ Writing of **comprehensive technical specifications**: diagrams (UML/BPMN), data model, deployment diagram.
◉ Definition of **interface contracts**: REST APIs (OpenAPI/Swagger), JSON schemas, error/versioning rules.
◉ Framework validation with2 development teamsand elaboration of theproject plan(milestones, risks, deliverables).
◉ Leading theKick-offalongside the client: stakeholder alignment, governance, and collaboration methods.
