About
A junior developer with a builder's mindset.
I'm Firzus, an Agentic / AI Developer with a full-stack foundation and a game-dev practice.
I learned to ship by building — from full-stack web apps to game prototypes in Unity and Unreal. Today I focus on agentic AI: tooling, workflows and products where LLMs do real work, not demos.
I care about rigor as much as speed: typed code, server-side rendering, internationalization and content-as-code. This portfolio is itself a case study of that approach.
