Balaji Kumar

I’m a Senior Software Engineer focused on building and scaling backend systems with .NET microservices, event-driven workflows, and strong engineering standards. Most recently, I led the migration of a legacy monolith into 16+ domain-driven microservices, defining service boundaries and data ownership.

I design for reliability and observability: I implemented gRPC-based inter-service communication and message-driven workflows, and I built end-to-end structured logging and distributed request tracing using correlation IDs and Azure Application Insights. I also engineered a GraphQL aggregation layer to reduce REST endpoint dependency and improve flexible internal data retrieval.

I’m equally hands-on with platform efficiency and performance—driving processing of 250M+ operations per year and cutting p95 latency by 35%. I’ve delivered zero-downtime, two-phase data migrations (snapshot backfill plus event-driven write replication) and created a standardized .NET microservice starter framework with built-in resilience, Redis caching, containerized scaffolding, and consistent API standards, while mentoring teams through code reviews and architecture discussions.
