I will build custom full stack web app features with backend API integration
Elod V.
About this gig
Need a custom feature added to your existing full stack web app?
I can build clean Java / Spring Boot backend changes, Vue.js frontend updates, REST API integrations, dashboard features, admin panel features, and PostgreSQL-related improvements.
I can help with:
- Java / Spring Boot backend development
- Vue.js frontend development
- REST API implementation
- PostgreSQL database integration
- Forms and validation
- Business workflow features
- Dashboard and admin panel features
- Frontend/backend data flow
- API integrations
This gig is best if you need more than a small bug fix: a focused feature, complete frontend/backend workflow, or small module added to an existing web application.
My goal is to deliver clean, readable, maintainable code that fits your existing project structure.
Every delivery includes a short summary of the completed work. Detailed technical documentation is available as an optional add-on.
Please send the feature description, expected user flow, examples or wireframes, repository access, and setup instructions.

FAQ
What kind of features can you build?
I can build frontend and backend features, REST API workflows, database-backed functionality, forms, dashboards, admin features, validation flows, business logic, API integrations, and improvements to existing web applications.
What technologies do you work with?
My main stack is Java, Spring Boot, Vue.js, JavaScript, REST APIs, and PostgreSQL. I can also work with related tools and existing project structures if the scope is clear.
What do you need before starting?
Please provide a clear feature description, expected user flow, screenshots or wireframes if available, repository access, setup instructions, and any business rules or permissions related to the feature.
What if the feature is bigger than expected?
If the feature turns out to be larger than the selected package scope, I will explain the situation before continuing. We can then agree on the next step, upgrade the scope, or split the work into a separate task.
Is technical documentation included?
Every delivery includes a brief summary of what was completed. Detailed technical documentation, including implementation notes, changed files, API/database details, and testing notes, is available as an optional add-on.
