About Rushitha K

I’m a Software Engineer with 4+ years of experience building scalable backend systems using Go and Java across fintech and insurance domains in the US and India. I specialize in designing microservices, RESTful APIs, gRPC services, and event-driven architectures that power high-throughput platforms with strict reliability, security, and performance requirements.As a Golang developer, I leverage Go’s concurrency model with goroutines and channels to build high-performance services capable of processing millions of transactions with sub-100ms latency. I have hands-on experience with Gin, Echo, Gorilla Mux, Protocol Buffers, Kafka Streams, and real-time data pipelines, enabling efficient service communication and resilient distributed workflows.At American Express and AIG, I contributed to mission-critical systems serving 10M+ users and 100K+ requests per second, including a large-scale migration of 500M+ records from Elasticsearch to Google Firestore with zero downtime, reducing cloud costs by 25% and query latency by 30%. I’ve built cloud-native solutions using AWS, GCP, Kubernetes, Docker, and CI/CD pipelines, and worked with data platforms such as Glue, Redshift, EMR, S3, and Athena.I’m passionate about writing clean, maintainable code, implementing automated tests, optimizing system performance, and improving observability with Prometheus, Grafana, and structured logging. I enjoy collaborating across teams, mentoring engineers, and delivering reliable, production-grade backend platforms that create measurable business impact. Open to Backend / Platform Engineering opportunities in the US.

Experience

1. Golang Developer

   American Express

   Sep 2024 — Present · AZ, US

   I engineered web applications using Golang and PostgreSQL, following Agile/SCRUM methodologies for continuous, iterative development. I developed microservices using Gorilla RPC, integrating with services like AWS SES and SendGrid for email handling, and utilized frameworks such as iBATIS with Spring for data persistence and transaction control. My backend services leveraged GORM, ADO, and multiple databases including MS SQL Server, Oracle, MS Access, and MongoDB, incorporating stored procedures, triggers, and advanced SQL techniques. I created and deployed Dockerized Golang applications on AWS and Confidential Linux, and later scaled deployments using Kubernetes and OpenShift. On Google Cloud Platform (GCP), I developed Cloud Functions and Compute Engine services in Go, processing both API and file-based events, and handled asynchronous messaging using Cloud Pub/Sub.I also worked on IoT microservices for capturing and printing meeting conversations, enhancing performance with concurrency tools like goroutines. My frontend contributions included building UIs with Angular and Redux, enriching interactivity using CSS3, DOM APIs, and AJAX. I strengthened application security with SQL, LDAP, and group-level access controls, and implemented JWT-based workflows and SSO/SAML authentication across services. I wrote and maintained unit and integration tests using Ginkgo, Selenium, and shell scripts on Linux. Additionally, I managed Elasticsearch, Redmine, and version control with Mercurial, while also integrating tools like Nginx, WebLogic, and GoCD to support infrastructure and CI/CD pipelines. My architectural work included optimizing UML designs using patterns such as DAO, Factory, and Service Locator.
