About this gig
Need a React JS app that handles real traffic - without breaking, slowing down, or falling apart?
I build high-performance React web apps with Node.js on the backend - clean architecture, fast load, ready to scale from day one.
What you get:
- Full-cycle web app development - from idea to launch
- React + Node.js stack built for performance and growth
- AI-powered tools, SaaS, e-commerce, marketplaces, healthcare - done it all
- 10+ years of experience, zero guesswork
This isn't template work.
Every React JS app I build is scoped to your business logic, your users, your scale. No shortcuts that come back to bite you later.

FAQ
Can you help refine the project idea or scope?
Yes. We help structure ideas into clear scope and priorities. Our in-house marketing team can also validate the concept, run market research, and help shape a product aligned with real demand.
Can you work with an existing product or codebase?
We typically focus on building custom products from scratch, but we can work with existing codebases. We start with an audit to assess quality, risks, and scalability, then define the best way forward.
How do you ensure the product is secure?
We build with security and compliance in mind from day one. This includes secure architecture, access controls, data protection, and best practices aligned with standards like GDPR or HIPAA where needed. Regular reviews and testing are part of the process.
What is considered as features expansion and enhancements beyond initial concept?
Feature implementation supposes addressing a scenario “user can do this and this -> and accomplish that goal / get that result” that is agreed in advance. In case feature expansion is necessary we add it to the Parking lot (backlog) and can form new sprint(s) of it.
How do you deal if during development customizations to design needed?
Customizations to the design - change of the style. Current designs provide a certain style guide for components. Style guide and designed screens are set as part of development. In case to re-do the whole designed page /change the style - forms a separate scope.
Do you require full payment for the project or can payments be split into milestones?
We typically work on a sprint-based payment model, where each sprint is paid separately. This ensures transparency, flexibility, and steady progress aligned with delivered results.
What's your engagement terms and payment process?
We would like to ensure a safe and productive environment where your products can grow and receive maximum attention, devotion, and expertise. By depositing investments into your product upfront you’re securing resources for success. If no results are produced - we guarantee a refund.
Will I own the source code and intellectual property of the product?
Yes. You fully own the source code and IP after payment is completed. We provide full access, repositories, and documentation to ensure full transparency and control.
Do you help with product launch and deployment?
Yes. We handle deployment, infrastructure setup, and production release. Ongoing support is provided via separate support plans, where we monitor, maintain, and update the product post-launch.
How do you deal with bug fixes, ongoing support and maintenance after the application is built?
Bug-fix within sprints - free. After sprints are accepted - we fix things that make the app unusable (free) - server errors/blockers. Other items go to the backlog and are handled in 2 ways - by sprints or hourly rate. For support, we set a monthly hours cap, during which we check and update the app
