Maximilien S.

Job Summary: Focused on automating, ensuring the reliability, and modernizing a strategic middleware platform. I built CI/CD pipelines, managed infrastructure as code, and facilitated team collaboration in a large-scale Agile environment.

Infrastructure as Code & Automation: Managed infrastructure using Terraform and automated system and application configurations with Ansible. Developed Bash automation scripts for the Linux environment.

CI/CD Pipeline Engineering: Designed and implemented robust CI/CD pipelines with Jenkins to enable frequent, reliable, and regression-free platform deployments.

Cloud Migration and High Availability: Led the migration of the platform and its databases to a more resilient and scalable cloud architecture, ensuring high availability.

DevSecOps and Observability: Integrated security requirements into DevOps processes (DevSecOps) and configured monitoring with SIEM integration for incident detection and compliance.

Agile Collaboration (SAFe) and Documentation: Served as the technical interface between Dev, Sec, and Ops teams within the SAFe Agile framework. Authored technical documentation, operational procedures, and runbooks.

Job Summary: Designed, secured, and integrated APIs on an API management platform (Apigee). I extensively used Python for automation and scripting while implementing enterprise-grade security standards.

API Development and Architecture: Designed and developed API proxies (REST/SOAP) on Apigee, acting as a security and abstraction middleware for a portfolio of backend services.

API Security and Identity Management: Implemented authentication/authorization flows (OAuth 2.0, SAML) and integrated with identity providers (Keycloak, LDAP). Configured security policies (quotas, spike arrest, SSL/TLS certificate validation).

Automation and Scripting (Python/DevOps): Created Python and Bash scripts to automate the lifecycle of Apigee configurations, certificate management, and testing. Utilized Docker and GitLab CI/CD for deployment industrialization.

Documentation and Quality: Authored technical interface specifications using OpenAPI/Swagger and developed integration test suites via Postman to ensure API reliability and documentation.

Job Summary: Responsible for the maintenance, evolution, and deployment of a critical web application. Notably, I led technical stack modernization projects and developed complex business features in Python (Flask).

Migration and Modernization: Led the application upgrade to Python 3.7 and migrated the database from SQLite to PostgreSQL, significantly improving the platform's performance, stability, and security.

Backend Development (Python/Flask): Designed and developed critical backend modules, including a logging system, a custom admin panel, and RESTful APIs for internal needs.

Automation and Data Processing: Developed a Python automation script for comparing and validating data between systems, and created a dynamic report generation engine (Excel extraction, calculations, PDF export).

Frontend and UX Redesign: Completely redesigned the application's user interface using Bootstrap and custom CSS, aligning with client requests for a better user experience.

Deployment and Methodology: Managed deployments across the environment chain (development, pre-production, production). Authored technical and user documentation to ensure project maintainability.
