I am a Senior Backend Engineer with 6+ years of experience architecting and engineering high-throughput, distributed microservices and cloud-native systems. My primary technical depth centers on Go (Golang), Distributed Systems, AWS, and gRPC / Protobuf.

Currently at Kairos Technologies, I author HLD/LLD specifications, build high-performance Go microservices for mobile backends, optimize recurring data-processing pipelines from ~6h to ~3h alongside ~20m partial workflows, and instrument observability dashboards via Prometheus & Grafana. Over the course of my career across Kairos Technologies, Ascendion Engineering, Coforge, and NIIT Technologies, I have engineered core transactional ledger engines, automated ETL and schema-mapping workflows for 200K+ healthcare records on AWS, and built scalable Go and Spring Boot microservices with asynchronous task queues.
