About Me
From Bug Catcher to Quality Advocate

Who Am I?
Hi, I’m Natsiree. With over 18 years of experience in the tech industry – from global organizations to fast-paced startups – I’ve seen it all. I’ve spent my career mastering everything from Cypress and Selenium to CI/CD pipelines and distributed load testing.
But through all the code and automation, I discovered a vital truth: Quality starts with how you think.
The “With Natsiree” Philosophy
I founded With Natsiree to help shift the tech industry from “Bug Catchers” to “Quality Advocates”. In the old world, QA was the “Gatekeeper” – the person standing at the end of the line, waiting to say “No”.
I believe in a different way:
- Prevention over Detection: We should build quality in from the start (Shift-Left), not just find mistakes when it’s too late.
- QA as a Navigator: My goal is to help you stop being the “Braking System” and start being the “Navigator” that helps your team go fast and safe.
- Information for Risk: QA isn’t about perfection; it’s about providing the right data to manage business risk effectively
Verified Global Expertise
My technical skills are independently verified at the highest level. I am a member of the Toptal Talent Network, an elite community that accepts only the Top 3% of freelance talent globally after a rigorous screening process.
Whether I am leading a distributed team across countries (Bangkok, UK, Singapore, India, Vietnam, etc.) or building scalable automation frameworks, I bring a “Quality Advocate” mindset that transforms how products are built.
Join the Movement
I’m here to help QAs (whether Junior/Senior, Manual/Automation) and career switchers reach their “Golden Form”. My approach is focused on real-world scenarios that force you to analyze risk and business impact.
Let’s build quality the right way.
