Bhawna Gosain

Senior Backend Engineer with 8+ years of experience building and scaling high-throughput, data-intensive systems using Java, Scala, and Python. Over the course of my career, I have worked extensively with distributed microservices, event-driven architectures, and cloud-native deployments, mainly across domains like marketplaces, enterprise platforms, and media/communication products.

I’ve led critical initiatives such as migrating 30+ core microservices from legacy Thrift to gRPC with zero downtime, designing robust protobuf contracts, and creating shared client SDKs to standardize inter-service communication. I enjoy solving complex distributed systems problems, from handling edge cases in production to optimizing p95 latency and eliminating performance bottlenecks in PostgreSQL and Oracle through careful query tuning and data modeling.

Beyond core backend development, I am comfortable owning the full SDLC: gathering and refining requirements, designing system components, implementing features, writing comprehensive test suites, setting up CI/CD pipelines, and monitoring systems in production using tools like Jenkins, Azure DevOps, Datadog, and SonarQube. I’ve also worked with messaging systems such as Kafka and RabbitMQ to build reliable, fault-tolerant integrations.

I’m particularly interested in high-scale systems, performance optimization, and clean, well-tested code. Recently, I’ve been expanding my expertise into Apache Spark and big data processing to complement my backend and database experience. Outside of day-to-day development, I enjoy learning new technologies, mentoring teammates, and contributing to engineering practices that raise the overall quality and reliability of software delivery.
