I’m Sharath Gundlapally, a senior full-stack engineer with 6+ years of experience building backend and full-stack applications using Python, Go, Django/Django REST Framework, FastAPI, React, and TypeScript. I focus on designing reliable REST APIs, asynchronous services, and secure authentication/authorization with OAuth2/JWT, while validating inputs, applying rate limiting, and improving API standards and performance. In my recent roles, I’ve optimized PostgreSQL and Redis-backed systems to improve response times (including a reported 40% improvement), supported high-volume concurrency, and raised automated test coverage to 85%+. I also deploy containerized services on AWS and Azure using Docker, Kubernetes, Helm, and Terraform, and I maintain CI/CD pipelines for repeatable releases across cloud infrastructure.…I’m Sharath Gundlapally, a senior full-stack engineer with 6+ years of experience building backend and full-stack applications using Python, Go, Django/Django REST Framework, FastAPI, React, and TypeScript.
