Fare Alerts Application
Rearchitected event driven fare alert application handling 300 M+ events daily used across Ixigo,
PhonePe, ConfirmTkt
Optimized Cassandra with Leveled & Time-Windowed Compaction, Local Quorum, achieving 4K qps
and sub-5ms latency
Improved Kafka consumption by tuning partitioning strategy, fetch.min.bytes, concurrency, lag based
autoscaling
Created fare tracking engine with KStreams & ClickHouse, using mat views for airline, time-bucket,
and overall fares
Scaled daily fare alerts sent from 200K to 800K, improving engagement by 4.5x and 900 additional
