Jonnferth
About this gig
Need a reliable Rust backend or full-stack web application?
I will build or improve your web application using Rust, APIs, databases, and modern frontend technologies such as React, Vue, or Next.js.
What I can help with:
Rust backend and REST API development
Axum or Actix Web services
Database integration and data modeling
Authentication and authorization
React, Vue, or Next.js frontend integration
API integrations and third-party services
Performance profiling and backend optimization
Bug fixing, refactoring, and code reviews
Docker, deployment, and setup documentation
You receive clean source code, practical documentation, and direct communication from me throughout the project.
Please contact me before ordering and share your project requirements, current codebase, preferred technologies, target hosting, and expected deadline. I will review the scope and recommend the right package.
Each project is scoped individually. Performance improvements are validated against agreed requirements rather than guessed numbers.

FAQ
Can you build a Rust backend from scratch?

Can you connect the backend to my existing frontend?
Yes. I can connect Rust APIs to React, Vue, Next.js, or another frontend and work with your existing project structure.
Do I receive the source code?
Yes. Source code is included in every package unless a different arrangement is agreed before ordering.
What do you need before starting?
Please send your requirements, repository or API details, target platform, preferred stack, and deadline so I can confirm the scope.
Can you work with an existing Rust project?
Yes. I can review your existing Rust project, understand its structure, and add features or fix issues without requiring a complete rewrite.
Can you integrate third-party APIs?
Yes. I can connect your application to REST APIs, authentication services, payment providers, webhooks, and other external services when the required documentation is available.
Do you provide deployment support?
Yes. I can help configure Docker, environment variables, deployment documentation, and basic hosting setup. Hosting fees are not included.
Can you fix and optimize existing Rust code?
Yes. I can investigate bugs, review code, improve error handling, refactor modules, and optimize performance based on measurable requirements.
Can you work with authentication and databases?
Yes. I can implement or connect authentication, authorization, PostgreSQL, MySQL, SQLite, or another suitable database for your project.
