01 / IN PRODUCTION
Modernizing telecom operations.
Software Engineer · TechNarts
Sep 2025 – Present
STAR Suite, the telecom operations support platform used by Turkcell.
-
Platform modernization
Moved from the existing STAR Suite team to a three-engineer modernization team in February 2026, contributing to the rebuild of a large legacy codebase with Django, PostgreSQL, Redis, Kafka, and React.
-
Data at scale
Migrated telecom datasets ranging from hundreds of thousands to millions of records from MariaDB to redesigned PostgreSQL schemas.
-
Production performance
Reduced critical page response times from 20–30 seconds to 200–400 ms through query optimization, snapshot-based read models, and Redis caching.
-
Algorithms in practice
Developing graph-based fiber routing and network impact analysis to trace how faults affect connected infrastructure.
