What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my frontend expertise to create impactful user experiences while contributing to a dynamic team.

With over 12 years of experience in web application development, I have honed my skills as a Senior Frontend Engineer, currently at FoxyAI. My journey began as the first frontend engineer at a seed-stage AI-powered real estate analytics startup, where I played a pivotal role in driving a 2× increase in annual revenue. I excel in building modern frontend architectures using Next.js, React, and TypeScript, focusing on performance and reliability.

Throughout my career, I have developed innovative solutions, such as a canvas-based overlay system for property damage detection and integrated AI-powered features that enhance user experience. My collaborative approach has allowed me to work closely with backend and product teams to align on data strategies and feature insights, ensuring that our products meet user needs effectively.

Prior to my current role, I contributed to various projects across health tech, fintech, and B2B SaaS industries, developing responsive web applications and modular component libraries that improved design consistency and development efficiency. My technical expertise spans a wide range of frontend technologies, and I am passionate about creating intuitive user interfaces that drive engagement and satisfaction.
