## About Me

I have over 20 years of professional programming experience as a frontend and backend developer. Since 2024, I've been relentlessly studying game math, CPUs, GPUs, rendering, and game engines on weekends and evenings. In November 2025, I decided to go full-time into game development to work on my own engine and games.

## Vector Game Engine (2024-2026)

The engine and vector renderer is written in Rust using winit, gilrs, wgpu, kira, kurbo, vello, velato and other utility crates.

Development started after a lot of research and experimentation with game engines written in rust late 2024 and from September 2025 I have been working full time on it.

It's closed source for now, but a lot of underlying the tech is open source.

## Vello & Vector Graphics

A GPU renderer for 2D vector graphics with CPU-side preprocessing.

Vello GPU uses the Sparse Strips architecture to divide work between CPU preprocessing and GPU rendering:

The CPU processes paths, tiles, and schedules sparse strips.
The GPU rasterizes those strips and performs compositing.
The compact strip representation limits data transfer between them.

Vello provides tools to render shapes, images, gradients, text, etc, using a PostScript-inspired API, the same that powers SVG files and the browser \<canvas\> element.
