I’m a Backend Developer with 15+ years of experience building and maintaining web applications, primarily with PHP, MySQL, REST APIs, and frameworks such as Zend and Laravel. What makes me unique is my ability to combine problem-solving with a strong focus on performance, data integrity, and process automation. At Superlógica, I helped reduce credit operation processing time by 70%, and at OneTouch Health, I optimized a large PHP platform while working remotely with an international team. I’m looking for a remote Senior Backend Developer role where I can contribute to reliable, scalable systems, improve existing applications, and help solve challenging technical problems.

- Healthcare platform development and maintenance: Developed and maintained a monolithic PHP platform for healthcare management, covering scheduling, billing, HR, and service monitoring modules.
- Performance optimization: Refactored queries, removed redundant calls, and added indexes on critical tables, cutting page load times from up to 120 seconds to near-instant on many screens and 10 to 15 seconds on the heaviest ones.
- Legacy code refactoring: Fixed syntax issues and centralized the most duplicated functions of the PHP monolith into a shared file, removing duplication and preventing components that should behave the same, such as modals, from drifting apart.
