The Narrative

CRAFTING DIGITAL
ECOSYSTEMS.

I don't just write code; I engineer solutions. With a background in Computer Science and a passion for Visual Arts, I bridge the gap between robust backend logic and fluid frontend interactivity.

My philosophy is simple: User Experience is King, Performance is Queen. Whether it's a high-frequency trading dashboard or a cross-platform mobile app, I ensure every pixel serves a purpose and every byte is optimized.

Currently, I'm obsessed with Realtime WebSockets and 3D WebGL interactions.
