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!
