I’m a fullstack developer with 2+ years of experience building web and mobile applications with React, Next.js, and Node.js—built for production from day one. I enjoy delivering reliable user experiences and well-structured backend services.

In my roles, I’ve built and maintained web interfaces and backend services, developed and consumed RESTful APIs, and automated business workflows with n8n (data pipelines and integrations). I’m comfortable working in fully remote, asynchronous environments.

I’ve also shipped platform features end-to-end: from Next.js API Routes using TypeScript (BFF pattern) to handling chunked audio uploads, pre-signed AWS S3 URLs, validation, and MongoDB persistence. I focus on practical architecture that gets projects launched and iterated quickly.

My toolkit spans frontend, backend, and cloud—React, Next.js, React Native, Node.js/Express, MongoDB, and AWS S3—so I can build complete solutions, not just parts. I bring a workflow-driven mindset and attention to real-world integration details.
