Message

At Nokia, I maintain server infrastructure and manage Kubernetes environments, while automating deployments with Ansible and improving CI/CD pipelines in Jenkins. Earlier, I developed Go web services and built a LangGraph agent that generated code from domain-specific knowledge, performing about 30% better than GitHub Copilot on internal code.

At Solvemed, I developed a data-preparation tool for machine learning and helped ensure training-data quality. I also developed a Slack bot at Xperi and migrated web services from RabbitMQ to Kafka; for UniQueue, I built React views and a Kotlin backend integrated with university authentication.
