Ivan Korotkov

Lead Go Developer at Aviasales · Belgrade, Serbia

I build high-load backend systems in Go: storage, data ingestion and APIs that stay fast under heavy traffic.

Now

• Leading the team behind Aviasales' flight ticket price cache: point and wide queries, near-real-time data, millisecond latency
• Maintaining iskorotkov/avro, the continuation of the most popular Go library for Apache Avro
  • faster encoding/decoding of complex structures
  • 3 high-severity DoS fixes (CVE-2026-46384, CVE-2026-46385, GHSA-mx64-mj3q-7prj) and fuzz testing
  • migrating from github.com/hamba/avro? Switch the import to github.com/iskorotkov/avro/v2
• Writing about Go performance and concurrency on Habr
