CV
I’m an experienced and detail-oriented Full-Stack Developer with a strong technical mindset and a passion for building robust, scalable applications. My background spans frontend and backend development, modern JavaScript frameworks, and a deep understanding of architecture, performance, and developer experience.
I’m confident working across the full stack — from crafting responsive, accessible user interfaces with React or Vue.js, to designing reliable backend systems using Node.js and SQL. I place a strong focus on maintainable code, thoughtful abstractions, and clean architecture patterns.
In my workflow, I apply modern build systems, automated development pipelines, and advanced version control strategies to ensure code quality, consistency, and fast iteration. I’m experienced in automated testing, component-driven development, and continuous delivery practices that support sustainable, long-term growth.
Beyond web development, I enjoy building cross-platform mobile apps using Flutter and Dart, and have a growing passion for game development — particularly working with Blender, Unreal Engine, and C++. I’m fascinated by the intersection of art, design, and engineering in interactive 3D environments.
I thrive in collaborative teams, and constantly seek to push the boundaries of what I can create — whether in web, mobile, or real-time 3D.
