Human Design API.

Accurate astrological and Human Design calculations are computationally expensive and usually hidden behind proprietary, opaque systems. Developers lacked a high-performance, developer-first API for granular data access.

I developed a scalable FastAPI engine that performs complex ephemeris calculations in real-time using C-based extensions. To handle deeply nested data structures, we implemented 'Recursive Masking' logic, allowing consumer apps to surgically request only the required data points, reducing total payload size by 70%.
