What I'm looking for

I'm looking to build scalable, user-centric web applications with cross-functional teams, where I can create reusable interfaces, improve performance, and contribute to reliable frontend architecture.

At Palette, I build internal applications and custom features for an international team using React, Next.js, TypeScript, and Vite. I create reusable UI components and design systems that keep products consistent and scalable.

Previously at ESTOCA, I developed Shopify app features for complex logistics and e-commerce workflows. I built merchant controls for shipping rules and cart pricing, optimized frontend performance, and contributed Python, FastAPI, and PostgreSQL features.

At VEXPRO Business IT and Clina.care, I modernized legacy interfaces, built component libraries, supported payment integrations, and worked on responsive healthcare booking experiences. I've also collaborated on GraphQL APIs and microfrontend architecture.

I care about clean, reusable code, automated testing, and user experiences that stay reliable under change. My background also includes Python/Django chatbot development and web application vulnerability analysis.
