I improve mobile product quality, support workflows, and client SLAs through practical QA.
SpainWhat I'm looking for
I've improved quality for mobile advertising products at Chartboost, Unity, and ironSource, testing HTML playable ads, mobile platforms, APIs, and related products.
At Unity, I led three QA and Support Engineers across countries, transitioned QA workflows from Jira to Salesforce, and reduced client SLA by more than 50%. I also improved testware to uncover more failures while cutting test-run time by 10–30%.
My earlier support work at AllStars-IT and Ajax Systems strengthened my client communication, issue investigation, re-testing, and infrastructure support skills. I enjoy investigating day-to-day operational challenges and finding data-driven ways to improve quality, processes, and customer care.
