David Calalang Email & Phone Number

As a dedicated and results-driven Quality Assurance professional with almost 2 years of experience, I specialize in ensuring the highest levels of product quality and user satisfaction through meticulous testing, process improvement, and collaboration. With a strong background in software testing methodologies (Agile, Waterfall, and DevOps), automated testing tools (Postman), and continuous integration, I’m committed to delivering robust, error-free software that meets the needs of both businesses and end-users.Over the course of my career, I’ve significantly contributed to the enhancement of product quality, most recently achieving a 40% reduction in software defects and 20% faster time-to-market by streamlining testing processes. My ability to identify and resolve complex issues whether related to functionality, performance, or security has consistently driven operational efficiency and improved user experience.My approach to QA is both analytical and collaborative. I work closely with cross-functional teams including developers, product managers, and stakeholders to prevent defects early and drive quality through all stages of the product development process. By performing rigorous functional, regression, performance, and security testing, I help ensure that products meet the highest standards of reliability and performance.
