What I'm looking for

I'm looking for a remote role where I can contribute to product quality through hands-on QA work and collaborate with a team that values clear communication, user experience, and continuous improvement. Opportunities to grow my automation and development skills alongside testing are a big plus.

I'm a QA Specialist and Web Developer with hands-on experience in manual testing, API testing (Postman, JMeter), UAT coordination, and bug reporting using tools like Jira. I’ve worked on both fintech and client-facing platforms, handling test documentation, reproducing bugs, and collaborating with dev teams to ensure smooth, high-quality releases.
My background is in Applied Computer Science, and I co-authored a published IEEE paper on machine learning for carbon emissions mitigation. I’ve also developed live websites (including New KPCU), participated in innovation-focused hackathons, and volunteered in climate change initiatives.
I enjoy solving real-world problems through tech, and I'm constantly exploring better ways to test, document, and communicate within agile product teams. My interests lie in tech-for-good, clean code, and delivering great user experiences.
