Frontend developer and QA tester creating responsive, SEO-ready experiences.

What I'm looking for

I’m looking for a role where I can build responsive frontend experiences, own user flows, and ship confidently with practical QA. I enjoy collaborating with stakeholders, improving performance, and strengthening SEO/GEO through clean, maintainable code.

I’m a Frontend Developer & QA Tester who builds clean, high-performing interfaces and pairs that work with hands-on testing. I combine strong UI/UX instincts with practical engineering to deliver reliable digital experiences.

At Isracard, I manage content upload and updates across the company’s website and app, including publishing articles and creating new pages. I configure and maintain end-to-end user flows for credit card issuance and loan applications, while coordinating with external partners on SEO and GEO strategies.

I’ve worked across multiple CMS and delivery systems, including Wix, Umbraco, EPiServer, and Inwise. I also collaborate with stakeholders and handle a heavy, diverse workload using effective time management.

Previously, I built scalable frontend UI components and backend features during my internship and earlier roles, integrating API services and client-side logic. I’m ISTQB-certified (Foundation Level), participate in code reviews and debugging, and work with agile (Agile / Scrum) best practices for maintainable code.
