At NetCracker, I support a large enterprise telecom application and its Oracle Database, PostgreSQL, and REST-based integrations. I investigate production and customer-reported issues across system components, and contributed to a 30% application performance improvement.
In earlier NetCracker roles, I supported telecom data migration and integration workflows, using SQL and PL/SQL to investigate failures and validate data integrity. I also used Kafka-based flows, Prometheus metrics, and database records to investigate system behavior.
At NetCracker and AutoVAZ, I worked with customers and business users to clarify issues, analyze logs and database data, and coordinate resolutions with technical teams. I created technical documentation for integration behavior, solutions, and troubleshooting.
