Front-end developer at Candidly delivering debt management solutions with React and TypeScript.

Argentina
Message

At Candidly, I delivered end-to-end solutions for a US-based debt management application. I used React and TypeScript across projects that included a React app, a Next.js app, and a WordPress site.

I implemented designs from Figma and worked closely with the design team to share a technical point of view. I also used AI tools for planning and development, developing skills and commands and integrating with MCPs.

At Distillery, I built an account dashboard for an insurance management web app and led its migration from JavaScript to TypeScript. I integrated a third-party insurance provider SDK and created an npm package to share business logic between web and mobile apps.

At Mercado Libre, I built web apps from scratch, developed custom React hooks, and worked on CSV upload and download flows. Before software development, I taught and performed music; I still compose and perform as a freelance session musician.
