Building for the web.

Fullstack development with React, Next.js, Node.js, and TypeScript. From intuitive frontends to robust serverless APIs.

About

A bit about me

I'm a fullstack software engineer with over three years of experience building scalable, user-friendly web applications. I specialize in React, Next.js, Node, and TypeScript, and enjoy working across the entire stack.

Before software, I pursued a deep passion for music as a classical guitarist. I hold both a Bachelor's and a Master's degree in Classical Guitar Performance.

My background in music fuels my attention to detail and creativity, which I bring into every project. Over the years, I've honed my skills with technologies like React/Redux, Express, Flask, Sequelize, and SQLAlchemy, always eager to learn and solve challenging problems.

I've worked in fast-paced startup environments where I led architecture discussions, developed modular UI components, and built secure, scalable backend services.
