I’m a Software Development Engineer Intern who enjoys turning complex workflows into dependable backend services. At Razorpay, I worked on the Cross-Border Import platform, supporting international payment processing and merchant settlement workflows end to end.

I improved cross-border settlement reliability by implementing support for refund-credit transactions and handling edge cases in asynchronous bank reconciliation. I also investigated production transaction processing issues by tracing execution workflows, repository queries, and service interactions.

My work emphasized production-grade engineering: I built backend services using Go, Gin, GORM, gRPC, MySQL, and Redis, and strengthened quality with unit tests using GoMock and Testify. I collaborated across environments using Kubernetes and Helm/Helmfile, validated deployments in AWS dev and pre-production, and used Coralogix and Vajra for monitoring and debugging.

Beyond payments, I build practical systems through projects like HELIX, where I designed a Unix-like command-line shell in Python using low-level OS interfaces (os.fork, os.execvp, os.pipe, os.dup2) with pipelines, redirection, and signal-aware behavior. I also created an end-to-end ML Model Deployment API with FastAPI, scikit-learn, Docker, model versioning, health-check endpoints, and CI-backed stability, plus freelance React/Node.js web platforms with live deployment support.
