Hi, I'm Offerrall
Self-taught developer since 2020. I enjoy building tools to solve my own problems and sharing them here in case they help others.
I write mostly in Python, dipping into C or CUDA only when I really need the extra speed.
Currently building a personalized products business. I open-source the general tools I create along the way.

GPU-accelerated image compositing for Python.
- Zero Dependencies: Works with standard NVIDIA drivers (No CUDA Toolkit/Visual Studio required).
- Studio Quality: 32-bit float precision throughout the pipeline.
- Massive Speedups: 10-200x faster than CPU for blur, blends, and transforms.
- Smart Memory: Buffer reuse for zero-allocation video/batch processing.
- Rich Features - +40 operations (gradients, blend modes, effects...)
