As a seasoned engineer, I have a strong background in data infrastructure, data science, and backend development. I bring hands-on experience in DevOps practices, including CI/CD pipeline design, infrastructure as code, and system monitoring.
I have extensive experience working with public cloud platforms (GCP and AWS), as well as deploying and scaling pipelines in on-premises environments. I excel at optimizing system performance, ensuring reliability, and continuously improving deployment workflows.
