What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

As a Senior Frontend Engineer with 9 years of hands-on experience, I specialize in building high-performance, scalable, and user-focused web applications. My expertise lies in modern JavaScript frameworks such as React, Next.js, Angular, and Vue, where I have successfully led frontend initiatives across fintech, healthcare, and SaaS platforms. My proven track record includes optimizing website performance, enhancing user experiences, and ensuring compliance with industry standards.

Throughout my career, I have played a key role in developing and maintaining complex applications, including a multi-asset trading platform and a HIPAA-compliant healthcare solution. I am adept at collaborating with cross-functional teams, mentoring junior developers, and advocating for best practices in fast-paced, agile environments. My commitment to delivering impactful solutions is reflected in my ability to integrate advanced technologies and implement SEO best practices that significantly improve organic traffic.
