What I'm looking for

I’m looking for a frontend-focused role where I can ship high-performance React/Next.js products, improve reliability with strong testing, and use AI-assisted workflows to deliver features faster while collaborating in a Scrum team.

I’m a frontend developer with 3+ years of experience delivering dashboards, CRMs, and web applications for clinics, e-commerce, and content platforms. I reduced load times by 90% through React/Next.js optimization (SSR/SSG) and accelerated feature delivery by 75% by integrating AI-assisted development workflows.

I specialize in React, Next.js, TypeScript, testing (Jest/RTL), and CI/CD with GitHub Actions and continuous deployment on Vercel. I’ve also built a patient management panel used by 200+ healthcare professionals, integrating Dialogflow and interactive visualizations with Chart.js, and I bring a collaborative Scrum approach from my web development experience.
