IT Specialist

About

Nearly 4 years in QA across web and desktop apps, REST APIs, embedded systems, and hardware validation - enough variety to understand that quality isn't a testing phase, it's a project-wide mindset.I work to make that visible early: catching misaligned requirements before they become bugs, asking the uncomfortable questions during refinement, and using my cross-domain experience to help teams ship coherent, consistently reliable software.
