I will build a responsive web app or dashboard with react and node js
Hanna Salinas
About this gig
Need a fast, reliable web app but not sure where to start?
I'm a full stack developer specialized in React, Node.js and SQL/MongoDB databases. I build clean, functional, production-ready applications, from landing pages to dashboards with real-time data.
Why trust my work: my portfolio includes real projects, not just practice exercises. Terrall is an interactive 3D map of Colombia with an advanced frontend and geospatial data visualization. I also built an HR data warehouse with SQL Server, Docker and full ETL pipelines, plus a management system with a MongoDB backend, authentication and CRUD operations.
What's included: clean, well-commented and maintainable code; responsive design; database integration with SQL or MongoDB depending on your project; and clear communication throughout the process.
Message me before ordering so we can define the exact scope of your project.
