What I'm looking for

I seek senior frontend/full-stack roles building scalable, user-centric web applications with React/Next.js, Node, and AWS. I value collaborative Agile teams, strong CI/CD practices, performance optimization, and opportunities to mentor and drive technical improvements.

I am a Senior Frontend/Full Stack Developer with 9+ years of experience designing, developing, and deploying scalable, high-performance web applications across eCommerce, healthcare, and SaaS industries. I build user-centric, responsive interfaces and production-ready backend services using modern web technologies.

At Amazon I developed eCommerce features with Next.js, Node.js, and PostgreSQL, refactored backend services into modular microservices using GraphQL and REST, and automated CI/CD with GitHub Actions deployed on AWS Amplify. I also integrated Stripe for payment workflows and improved backend performance by 35%.

At UnitedHealth Group I helped build a SaaS platform using React and PHP with a MySQL backend, created unit and integration tests with React Testing Library and Jest, and designed role-based authentication using JWT and OAuth2. I reduced onboarding time by 60% through workflow redesign and automation, and set up Docker-based GitLab CI/CD pipelines that cut release errors by 25%.

I collaborate closely with designers, product managers, and DevOps teams, and I follow Agile/Scrum, TDD, and DDD methodologies. I am passionate about building maintainable component libraries, reliable APIs, and efficient cloud deployments that deliver measurable business impact.
