Profile: https://flows.cv/brayan

I'm a Software Engineer with 6+ years of experience designing and building scalable full stack applications using JavaScript, Scala, and Python.

My background includes work on backend services, APIs, ETL pipelines, and modern frontend interfaces with frameworks like React and Angular. I specialize in distributed systems and microservices running in cloud environments, especially AWS.

I thrive in cross-functional teams where I can combine clean code, system design, and product thinking to build real-world solutions that scale.

I'm currently open to remote software engineering roles with U.S.-based teams. I’m based in Australia and able to align with U.S. time zones.
