At Junglee Games India Pvt Ltd, I scaled the in-game currency and wallet platform to handle millions of concurrent requests with low latency and high availability. I redesigned Spring Boot microservices around Kafka event streaming and Redis caching.
I improved wallet transaction reliability by designing idempotent REST APIs and using Kafka retries, dead-letter handling, and Redis-based locks. I also wrote JUnit and Mockito tests for transaction and wallet flows.
On 1klik, an algo trading platform for the Indian stock market, I built a Spring Boot backend that integrates with broker APIs. I used Redis for fast access to live prices and MongoDB to preserve order, position, and strategy history.
