What I'm looking for

I’m looking to build reliable, production-ready backend systems—FastAPI/Django REST APIs with strong authentication, clean code, and Azure deployments—while optimizing performance and owning API integrations and notifications.

I’m a Backend Python Developer with 2+ years of experience designing, developing, and maintaining scalable RESTful APIs using Python and FastAPI. I focus on production-ready systems, clean coding standards, and backend architecture that holds up under real-world demand.

I build secure APIs with structured request/response validation using Pydantic models and JWT-based authentication and authorization. I also work on SQL-based data handling, relational database design, and SQL query optimization to improve reliability and performance.

I’ve integrated third-party REST APIs by handling authentication, error scenarios, and data mapping. I’ve also developed custom email notification systems for OTP and transactional alerts, and integrated the Gupshup WhatsApp Business API with webhook handlers for delivery-status callbacks.

I deploy and manage backend services on Microsoft Azure (Azure App Services and Azure Functions) using CI/CD pipelines and Docker (basic). I enjoy performance optimization, debugging with strong problem-solving, and collaborating in Agile environments to deliver features end-to-end.
