What I'm looking for

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

As a Senior Software Engineer with 8 years of experience in modern web development, I am known for spearheading key technical projects and crafting high-impact user experiences. My enthusiasm for technology is matched by a focus on measurable results, ensuring that every project I undertake delivers value to users and stakeholders alike.

Throughout my career, I have successfully led initiatives that have transformed customer-facing features and improved overall user engagement. At Box, I played a pivotal role in transitioning our frontend from JavaScript to TypeScript, which not only enhanced code quality but also streamlined our development process. My collaborative approach with UI/UX and product teams has resulted in significant increases in user satisfaction and engagement metrics.

I am passionate about leveraging my technical expertise to drive innovation and efficiency within teams. I thrive in environments that challenge me to think critically and creatively, and I am always eager to embrace new technologies that can enhance my work and the experiences of the users I serve.
