About Me

Frontend developer specialized in React and React Native (Expo / Expo Router / EAS), with experience in Next.js (App Router). Strong in UI architecture, state management (Zustand), async data (TanStack Query) and API consumption with Axios.

I have worked on complex projects from inception to production, including RBAC flows, Android devices and payment terminals. I contribute to technical decisions, performance optimization and continuous product improvement.

I integrate AI-assisted development tools (Cursor, MCP servers, OpenAI) into my daily workflow to ship faster and improve code quality. I also automate internal processes with n8n.

I am consistent, responsible and focused on code quality. I enjoy collaborating in agile teams, solving real problems and building solutions that add long-term value.

Currently open to remote or hybrid opportunities in product and technology environments.
