Back to original languageAbout Ayola Franck Oscar
Cloud DevOps Engineer and Full-Stack Developer (Back-End, Front-End & Mobile) with over 5 years of experience, I work with companies to effectively link code excellence (web and mobile) with the power of cloud operations. My dual profile allows me to design applications end-to-end while ensuring smooth, automated, and highly secure deployments.
My expertise is built around 4 pillars:
- FRONT-END, MOBILE & DESIGN: Design of dynamic, fluid, and responsive web and mobile interfaces (React JS, Angular, HTML5/CSS, JavaScript) and development of mobile applications (React Native). I pay particular attention to design, UI/UX, and prototyping (Figma) to offer the best possible user experience.
- BACK-END DEVELOPMENT & SECURITY: Architecture and development of robust applications, REST APIs, and PHP (Laravel) or Java (Spring Boot). Database management and administration (PostgreSQL, MySQL) and access security (Keycloak, OpenLDAP).
- CI/CD & RELEASES: Creation and optimization of automated pipelines (GitLab CI, Jenkins, Bitbucket) and advanced orchestration of complex releases (XL Deploy / XL Release) to streamline Time-to-Market.
- CLOUD, ROUTING & AUTOMATION: Complete infrastructure automation (Terraform, Ansible), management/orchestration of containers in production (Docker, Kubernetes), and secure traffic routing (Nginx as Reverse Proxy).
Rigorous, autonomous, and an advocate of Agile methodologies, I am used to working in demanding environments (telecoms, e-commerce, fintech). I am proactive in supporting your teams from the initial idea to production.
Available immediately to discuss your full-stack development, application creation, or Cloud automation projects!
