What I'm looking for

I seek roles where I can lead IoT and cloud initiatives, drive DevOps automation, and build secure, scalable edge-to-cloud systems in collaborative teams.

I am an engineer specialized in IoT with more than 7 years of experience designing, deploying, and automating IoT devices, backends, and infrastructure in cloud and containerized environments. I focus on Linux, CI/CD pipelines, Infrastructure as Code, container orchestration, and observability to deliver secure, scalable systems on AWS and Azure.

I have led technical projects and teams for Smart Cities, implemented MQTT brokers and LoRa networks, built dashboards and microservices for real-time monitoring, and driven automation with Ansible, Terraform, Docker, and Jenkins. I bring strong Python and Shell scripting skills, embedded systems experience, and a collaborative DevOps mindset to accelerate reliable product delivery.
