About

My work in telemetry team is focused around creating ETL/ELT jobs with the help of Apache Airflow to build data models inside our data warehouse in SQL server where we use them for reporting purposes. Main delivery from our team that I'm a huge part of is providing a Unified Data Platform to integrate data from Bitbucket, Jenkins, CS vendors, Kubernetes, LDAP, Copilot and other tools for mapping lineage and ownership at domain, application, and developer levels. Besides writing data pipelines I act as a db admin and I'm also maintaining micro services related to data models that I host on k8s which I deploy with simple Jenkins jobs.
