DevOps Engineer for carrier-grade telecom platforms and resilient backend infrastructure.

I work on production SMS Firewall systems for mobile network operators, combining Kubernetes migration, Linux administration, containerization, automation, incident response, and Erlang-based application support.

My backend work includes Spring Boot platforms with relational databases, Redis, reverse proxies, authentication, rate limiting, idempotency, and automated deployment pipelines.
