Sebastián Castillo Zamudio

At AVIS, I developed and maintain automation solutions for operational processes using NestJS, JavaScript, and AWS services. I also developed a worker and APIs to manage jobs, check statuses, and record process results.

I participated in automating workflows with BlueZone, including script execution, reservation processing, and communication with backend services. I implemented status validation, retries, and event logging to support communication and monitoring between local processes and backend services.

At FALCON TOOLS, I automated accounting, costing, analysis, and inventory processes with Excel macros, reducing response times by up to 80%. I also developed a tool to generate quotes automatically and standardize the process.

My projects include DevTree, a responsive web app for managing and presenting links, and a portfolio website deployed on Vercel. I’ve also developed a Java and Spring Boot application integrating Spotify services through a REST API, and a Java client-server communication project.
