Senior Software Engineer at Forkast building AI trading infrastructure and a Kafka-backed matching engine with crash recovery.

Message

At Forkast, I built the backend orchestration layer and LLM gateway for autonomous trading agents, including session-key delegation and a signing server that protects users’ private keys.

I also re-architected the Kafka-backed trade matching engine with staged consumer groups, a transactional outbox, and crash-recovery support. Across backend APIs and performance work, I reduced data delivery latency by 35% and API response times by up to 60%.

Before Forkast, I developed tournament and rewards systems, event-driven microservices, and GraphQL APIs. At Precize and Utkal Labs, I worked on payment and web3 integrations, client projects, and a client analytics dashboard.
