About

As a Software Engineer with 5+ years of experience, I build scalable, high-performance web applications end-to-end using React.js, TypeScript, Node.js, Express.js, GraphQL, PostgreSQL, and AWS. I specialize in full-stack development for B2B products, combining strong front-end engineering with robust, reliable backend APIs. At Fictiv, I lead and ship performance-focused initiatives on large-scale React frontends, improving user experience and page performance by 30% and reducing latency by 25% through AWS OpenSearch integrations, GraphQL/API optimizations, and client-side rendering improvements. Previously, at Red Panda Innovation Labs, I delivered production-grade full-stack features and built a reusable React + Storybook component library adopted across 4+ B2B products, improving development velocity by ~30%. I enjoy owning features across the stack: designing reusable component systems and design-system-aligned UI, implementing REST and GraphQL APIs, integrating with cloud services (AWS), and deploying and monitoring services in production using CI/CD pipelines. My focus is on scalability, reliability, maintainability, and great user experience. I also contribute beyond code — mentoring junior developers, conducting technical interviews, and driving best practices in automated testing (Jest, React Testing Library), CI/CD (GitHub Actions, Docker), and code quality across teams.
