You will get Stripe API integration and I will build reliable payment workflow
Project details
I will design and develop a scalable FastAPI backend using clean architecture and modern Python best practices.
This service is ideal for startups and SaaS platforms that need a reliable API capable of handling real users and business logic. I focus on writing maintainable, high-performance async code using FastAPI, Pydantic, and proper dependency structure.
I can help with:
• REST API development with FastAPI
• Microservices architecture
• Database integration (PostgreSQL, DynamoDB)
• AWS deployment (EC2, Lambda, API Gateway, S3)
• Secure and well-structured backend logic
• API documentation and testing
Even though I am new on Upwork, I have practical experience building backend systems and integrations. I follow industry standards to ensure your project is scalable, maintainable, and ready for production.
Clear communication and clean code are my priorities. I aim to build long-term relationships and deliver real value.
