What I'm looking for

I want to build scalable backend microservices and low-latency distributed systems—owning performance, reliability, and observability. I’m excited to work on event-driven architectures, messaging, and production-grade APIs with real-time constraints.

I’m a Backend Software Developer with 1.5+ years of experience building scalable microservices and low-latency distributed systems for high-frequency trading platforms. I focus on reliability and performance—scaling KYC, Re-KYC, and registration microservices to handle thousands of concurrent requests while keeping processing dependable through idempotent workflows.

I also engineer event-driven services and fast recovery paths using messaging and core state management, including a low-latency Symbol Search Service with in-memory caching and crash recovery through holdings state modules. In internships, I built low-latency HFT backend services with Golang, WebSockets, ZeroMQ, and NATS, integrated Keycloak for OAuth2/OIDC role-based access, and created backend APIs and pipelines with strong observability and production-minded deployments.
