I am looking for a backend developer in Python (Fast API / Django) for a small project to create a web service for building astrological charts (only 1 specific type with a Regiomontanus field system). I need a person with experience in scientific computing who can integrate the Swiss ephemeris library, set up a database of countries/cities and time zones. The priority is the accuracy of calculations, the visual concept can be quite simple. The site should include user registration/login, the ability to save built charts. I can provide more detailed information and an example of the site during the discussion.

Hello. Here is how I see the project.

I will do the backend using FastAPI. I will separate the calculation logic into a separate module, connect Swiss Ephemeris, and set up the construction of charts specifically according to the Regiomontanus system, without universal libraries that introduce errors.

For the date and location, I will use a database of cities with coordinates + IANA timezones, correctly handling UTC, daylight/summer time, and historical shifts. The input will be date, time, and location, and the output will be precise astronomical data that matches reference calculations.

Next, I will implement user registration and login, saving the constructed charts in a database (PostgreSQL), so that each chart can be restored or recalculated based on saved parameters. I will make the architecture simple and understandable so that the service can be easily scaled.

Before starting, I will compare the results with your example website, after which I will deliver the finished service and documentation.

We can discuss the details and example, after which I will provide specific timelines and scope of work.

Hello. I am interested in the project, I have experience in backend development in Python and working on tasks where accuracy of calculations is critically important (time zones, coordinates, mathematical logic).

I have worked with integrating third-party libraries, saving results for users, implementing registration and authorization. I am ready to carefully implement the logic of map construction with a focus on correctness and stability.

I am ready to discuss the details and an example of the site.
