Project details
You will get a production-ready Python FastAPI backend built with the same engineering standards I’ve applied on enterprise platforms for Disney, Booking.com, and Move.com, helping you launch faster, scale confidently, and avoid fragile backend architecture.
I build well-structured REST APIs with proper project architecture, PostgreSQL/MySQL integration, JWT authentication, Swagger/OpenAPI documentation, Docker setup, and AWS-ready deployment support. Your backend will be designed so your team can extend features, connect a frontend, integrate third-party services, and scale as your product grows.
This is ideal for MVP backends, SaaS platforms, admin dashboards, internal tools, AI applications, API-first products, and microservices.
Every package includes production-ready API endpoints, database models, JWT authentication, validation, and error handling. Higher tiers add background jobs, CI/CD setup, CloudWatch logging, and full deployment guidance.
You will receive documented source code and post-delivery support to help you test, deploy, and go live smoothly.

AI Email Dashboard — Gmail/Outlook Integration
I’m genuinely impressed with the work delivered on the AI Email Dashboard project. The integration with both Gmail and Outlook using OAuth was implemented seamlessly, making the sign-in experience smooth and secure without any need for installations. Your strong grasp of Google and Microsoft APIs was clearly reflected in how reliably the email data was fetched and processed.
The backend, built with FastAPI, is clean, efficient, and well-structured — ensuring fast responses and secure handling of user data. On the frontend, the React/Next.js implementation provides a modern, intuitive dashboard that’s easy to navigate, with a professional look and feel.
I particularly appreciate how you managed to deliver the MVP within the tight 7-day timeline without compromising on quality. The smart email digests and summary features are functioning exactly as envisioned, setting a solid foundation for future enhancements.
Your attention to detail, clear communication, and ability to translate requirements into a polished product made the entire development process smooth. Excellent job — this was a challenging build, and you delivered beyond expectations.
