>Building at the frontier of AI + Web.

Building end-to-end products — from APIs to polished interfaces — and exploring how AI reshapes what software can do. From computer vision to chat interfaces, I operate at the edge of intelligent software engineering.

Who I am & what I build

Software engineer with full-stack experience across React, Node.js, Python, and SQL. Currently building products at Zapier and studying Applied AI at UFPR. From YOLOv8 object detection to chat interfaces powered by LLMs, I'm obsessed with the intersection of clean engineering and intelligent systems.

Vancouver, Canada

Applied AI Focus

Postgraduate specialization at UFPR. From theory to production — PyTorch, computer vision, and LLM integrations.

Frontend Engineering

Building user-facing products at scale at Zapier. React, TypeScript, design systems, and performance.

Always Learning

Active researcher at the intersection of AI and web. Writing, experimenting, shipping — every week.
