I will build and deploy a full stack web application with the mern stack


About this gig
Do you need a complete web application built from scratch frontend and backend, fully connected and working together? I'm a full-stack developer who builds practical, user-focused web apps using React.js, Node.js, Express, and MongoDB (MERN stack), with growing expertise in Next.js and TypeScript.
I can help you with:
- Custom web application development (frontend + backend)
- React.js user interfaces with responsive design
- Node.js/Express backend with REST APIs
- Database design and integration (MongoDB, PostgreSQL)
- User authentication and account systems
- Deployment to a live, working site
I'm the founder of Journex Technologies and built Journex, a full-stack journaling and community platform, from idea to live deployment you can see the kind of finished product I deliver. I value clear communication, discipline, and integrity in how I work, and I'll keep you updated at every stage of the build.
Message me before ordering so we can scope your project properly!

FAQ
: Do I need to provide the design, or can you design it too?
I can work from your design (Figma, screenshots, or a reference site), or build a clean, functional design myself if you don't have one. Just let me know your preference when we discuss the project.
What if I need more pages or features than the package includes?
No problem — you can add extra pages or features using the gig extras, or we can discuss a custom offer if your project is bigger than the packages cover.
Will I get the source code?
Yes, source code is included from the Standard package upward. If you need it with the Basic package, you can add it as an extra.
Can you deploy the app so it's live and accessible?
Yes, I can deploy your app to a live hosting service (like Vercel, Render, or similar) as part of the delivery, so it's ready to use — not just files on your computer.
: I'm not very technical — can you still help me?
Absolutely. I'll walk you through the process in plain language, keep you updated at each stage, and make sure you understand what you're getting without needing to know how to code.
What technologies do you use?
I build with React.js for the frontend and Node.js/Express for the backend, with MongoDB or PostgreSQL for the database, depending on your project's needs.
