I am a Senior Computer Graphics Programmer and 3D Generalist operating at the intersection of high-performance coding, Generative AI, and artistic visualization. Not relying solely on abstractions, I have deep low-level expertise, having built my own WebGL rendering engine from the ground up. This foundational knowledge makes me exceptionally effective with frameworks like Three.js. I know what's happening under the hood, but I am equally comfortable building custom, lightweight solutions when performance is paramount. My skillset covers the entire pipeline, from server-side logic to raw shader programming: Graphics Programming: Expert in raw GLSL, vanilla WebGL, and Three.js. Whether you need a standard framework for rapid development or a custom lightweight engine for speed, I can adapt to the tech stack that best fits the project. Full Stack Development: I provide end-to-end web solutions, ranging from backend architectures using Node.js or PHP, to robust frontends built with React, or vanilla Typescript/JavaScript. AI & Hybrid Workflows: I build advanced pipelines that blend 3D precision with Generative AI. This includes developing custom Python nodes for ComfyUI to optimize product rendering and create flexible generation workflows. 3D Generalist: Extensive background in architectural and product visualization/modeling, allowing me to bridge the gap between technical constraints and visual fidelity. I prefer building clean, modular, and efficient solutions to solve complex visual problems.
