He runs marathons. He hunts bugs. Same mindset 🇻🇳
Meet Thien — a Diamond Level Tester from Vietnam 💎 who discovered Test IO in 2023 as an intern in Ho Chi Minh City, when a mentor pointed him in the right direction.
He passed the courses, started hunting bugs — and never stopped.
Two years later, he's completed multiple 42km full marathons across Vietnam, climbed mountains, and built a testing career that keeps growing. And according to Thien, all three pursuits are driven by the exact same spirit.
Here's what the road taught him about software testing:
↳ The start always feels overwhelming. Begin anyway.
↳ The hardest part is the middle — where no one's watching. Push anyway.
↳ The finish line hits different when you almost gave up. Keep going anyway.
Every mountain climbed. Every race finished. Every bug found after hours of searching — the same feeling. Worth every step.
