Work Experience

Senior Full Stack Python Developer at AT&T

November 1, 2024 - Present

I worked on async-first backend services using FastAPI with async/await to remove I/O bottlenecks in integration-heavy workflows. I delivered enterprise Django platforms with ORM, authentication, middleware, and admin features to accelerate complex workflows while maintaining stable releases. I standardized Python coding practices (3.12+, type hints, clean OOP) across services to reduce complexity and improve maintainability. I designed clean API contracts with REST versioning, pagination, and idempotency, and introduced GraphQL for data-heavy screens to improve UI responsiveness. I implemented JWT/OAuth2 with RBAC for least-privilege access, built responsive frontends with React/TypeScript, and established caching with Redis to reduce load. I automated deployments via Docker/Kubernetes on AWS/Azure/GCP and implemented observability and testing to improve reliability.
