I will create custom web tools with react and apis


About this gig
Are you looking to build a scalable SaaS, a custom web application, or a robust REST API?
Building a successful digital product requires more than just writing code; it requires a deep understanding of business logic, secure architecture, and maintainable systems.
I specialize in developing Full-Stack Web Applications and Backend Systems from scratch, tailored exactly to your business needs. With a strong focus on modular architecture and clean code, I ensure your platform is built to grow.
️ My Tech Stack:
- Backend: Node.js, Express, TypeScript, RESTful APIs, TDD (Jest)
- Frontend: React, JavaScript/TypeScript, Tailwind CSS
- Databases: PostgreSQL, MongoDB
- Infrastructure: Linux, Docker, Self-hosted deployments
What I can build for you:
- Complete Custom SaaS Platforms
- Secure User Authentication & Role Management (Admin/User panels)
- Custom Dashboards and Data Processing Systems
- Third-party API Integrations (Payments, etc.)
- Docker deployment setup for seamless hosting
Why work with me? I combine technical precision with a strong operational and business background. This means I don't just execute tasks blindly; I build reliable systems designed to solve real-world problems efficiently.

FAQ
Do you provide hosting and deployment services?
I do not provide the physical servers, but I will set up your application for deployment. For Premium orders (or as an extra), I will create Dockerfiles and a docker-compose setup so you can easily host the application on any VPS (like DigitalOcean, AWS, or Linode) running Linux.
Will I own the full source code?
Absolutely. Once the order is completed and approved, you will have 100% ownership of the final source code and all related assets.
I only need a Backend/API, not the Frontend. Can you do that?
Yes! I specialize in Backend development. If you already have a frontend team and just need a robust Node.js/PostgreSQL REST API, we can use the Basic or Standard packages, or I can send you a Custom Offer.
Can we integrate a payment gateway like Stripe?
Yes, payment integration is essential for SaaS platforms. This is included in the Premium package, or we can add it as a custom requirement to other packages.
