David K.
Agile Product Owner & Technical PM | SaaS & Healthcare | LQA Expert
Twelve years in, and I still test what I ship myself before it goes anywhere near a client's users. That's basically the whole pitch. I own product delivery, backlog, acceptance criteria, the works, across healthcare SaaS, iGaming, public media and fintech. Then I check my own output the way an outside QA team would. Some numbers, since job titles don't say much on their own. The OTP SimplePay integration I drove added around 3% to annual revenue. A mobile relaunch I led at a national broadcaster kept a 15% jump in video starts well after launch week wore off. A redesign I owned made pages and videos load three times faster, and time on site went up by about 25%. At New Wave Media Group I ran product strategy for an 8-site portfolio and managed a 5-person product and engineering team, reviews and development plans included. The QA part isn't a side gig I tacked on. I run manual and automated testing, mostly Playwright and Selenium, on web and mobile products. What I'm actually hunting for is what a script won't catch: a payment flow that technically passes but feels off, a chatbot reply that's correct but tone-deaf. I currently lead QA for an automotive-software testing practice, running a small team of vetted testers against a Swiss quality bar. One more thing. I'm a native Hungarian speaker. Need Hungarian-market localization or LQA on top of the PM or QA work? That's covered too.
