I'm a QA & Data Science enthusiast with 9+ years of experience delivering products that are smarter, faster, and future-ready. From functional testing to AI-powered insights, my mission is simple — turn complexity into clarity and precision.

I've cut testing cycles by up to 45% through scalable automation in Selenium, BDD, API, and performance frameworks. I transform raw data into actionable insights using Power BI, AWS, and advanced analytics while helping teams ship with more confidence.

I've also worked on elevating product accessibility and improving user experience for diverse global audiences — because quality should work for everyone, not just for the happy path.

Great products aren't just tested — they're engineered for excellence from the first line of code.

Exploring the intersection of AI, QA, and Cloud to create testing ecosystems that predict issues before they happen, accelerate delivery, and set new industry benchmarks.

If you're building something innovative or want to see how quality and data can drive real business results, let's connect.

My Thoughts

Unfiltered. Honest. Mine.

Lately I've been thinking a lot.
Nothing in my life is random. Most of it comes down to the choices I made… or avoided.
I don't really care about comfort anymore. I just want to reach a point where I'm in control — of my time, my money, my life.
Yeah, sometimes it feels like I'm behind. Like things should have been better by now. But at the same time, I know I'm not the same person I was before… and that counts.
I've stopped expecting things to magically work out. If it's going to happen, I'll have to make it happen.
I don't need everything to be perfect. I just need to keep moving and not lose focus.
Somehow, I trust that I'll figure it out.
