Paul Anthony Manguiat

I’m a computer engineering graduate with hands-on experience testing, debugging, and validating software across backend systems and APIs. I’m trained in structured QA methodologies using Postman and JMeter, and I focus on identifying bugs, edge cases, and configuration issues before release.

In my IT Intern role, I diagnosed and resolved defects across authentication, database, and configuration layers—like JWT validation errors and database connection conflicts—then verified fixes through repeated testing. I performed structured API and system testing using Postman (functional/API testing) and JMeter (load/performance testing), documenting test cases, defects, and resolutions for clear QA tracking.

I’m comfortable reading, running, and reviewing code across multiple languages (Golang, Dart, PostgreSQL) and I take pride in making backend logic easier to maintain through readability, consistency, and structure improvements. I work logically and methodically, especially when tracing root causes and confirming expected outcomes.

My project experience includes an Internship Management System where I built and debugged backend services in Golang, tested authentication flows with JWT Auth, and validated Flutter Web front-end behavior against backend logic. I’m self-motivated and reliable working independently on structured, task-based assignments.
