What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth opportunities in a dynamic team environment.

I am a Senior React/Next.js Developer with 10 years of experience in building performant and scalable user interfaces. My expertise lies in utilizing modern frameworks like React and Next.js, along with TypeScript, to create seamless user experiences. I have a proven track record of success in implementing server-side rendering (SSR) and incremental static regeneration (ISR) architectures, which have significantly improved application performance and SEO.

Throughout my career, I have collaborated on innovative projects, including AI-driven interfaces and integrated systems that leverage GenAI capabilities. My role at Upbound involved developing the core frontend for the Upbound Cloud dashboard, where I successfully reduced average page load times by 42% and improved infrastructure observability. I am passionate about mentoring junior developers and fostering a collaborative environment that emphasizes developer experience (DX) and modular design systems.
