What I'm looking for

I’m looking for a role where I can build reliable software end-to-end—payments, automation, and web apps—using Java/Spring Boot and Python, with strong teamwork, ownership, and a focus on testing, performance, and user experience.

I’m a junior software developer focused on delivering dependable features end-to-end—from implementation to release. I’ve developed and deployed two Colombian payment methods into a company’s payment gateway, expanding market coverage and improving the platform’s competitive position in Colombia.

At GoBravo, I used Python, Django, and Selenium WebDriver to build automation bots that reduced processing time and eliminated the need for manual work performed by 3 full-time employees. I also created Python scripts for data analytics to automate data processing and reporting, and optimized SQL queries to significantly reduce execution time and improve database performance.

I collaborate across the stack, contributing to web applications built with Java Spring Boot (backend) and Angular (frontend). I support product reliability with automated unit tests (over 75% code coverage), coordinate thorough pre-release testing, and provide timely technical support by addressing 100% of assigned requests to ensure customer satisfaction.
