Description

Tech Lead DevOps & Development & Observability, specializing in the implementation, modernization, and industrialization of Cloud and Kubernetes platforms.

I primarily focus on designing Cloud-native architectures, automating infrastructure and deployments (CI/CD, Jenkins, Infrastructure as Code – Terraform, Ansible), as well as the reliability, availability, and scalability of distributed systems.

I then developed strong expertise in the observability and operation of critical platforms: monitoring, logs, metrics, alerting, supervision of application and business services, with a focus on resilience, performance, and service continuity in production.

With a solid background in application development (PHP, C/C++, Java, JavaScript), I maintain a very close approach to the product and its uses.

I design and develop business applications (CRM, dialer, IVR, statistical interfaces) and ensure their integration within Cloud platforms.

My experience also covers the implementation of complete platforms:

Web (public / private), VOIP / telephony (SIP, Asterisk, Kamailio), SMS, messaging, VPN, streaming, with mastery of Linux, Docker, and Kubernetes environments.

I am involved from architectural study to production deployment, including technological choices, cost and performance optimization, team management, coordination with partners, and writing technical documentation, with a global vision oriented towards service quality and maintainability.
