React developers for web and mobile products that need to scale
TwinCore connects you with React developers from the TwinCore team who work inside existing products. They join ongoing projects, deal with real codebases, and help teams keep the frontend stable as features, traffic, and complexity grow.
You can hire one React developer or extend your team with several engineers. Either way, they onboard quickly and work within your setup, without forcing rewrites or changing how your team already operates.

Where React Developers from TwinCore Work Best
Long-Term Product Frontends
TwinCore React developers work on products that are expected to live and evolve for years. These are production frontends with users, ongoing feature development, and long-term maintenance requirements.
Scaling Existing React Codebases
When a React application grows faster than planned, structure and performance often suffer. TwinCore developers step into existing codebases, continue development without disruption, and help bring order back to the frontend without forcing unnecessary architectural changes.
React in Backend-Driven Systems
Many products rely on React as a client layer for complex backend systems built with .NET, Node.js, or microservices. TwinCore developers work comfortably in these environments, building React frontends that integrate cleanly with APIs and backend workflows instead of operating in isolation.
Admin Panels and Internal Tools
TwinCore React developers work on dashboards, admin panels, and internal platforms where clarity, reliability, and maintainability matter more than visual experiments.
React Native Applications in Production
For mobile applications already running in production, TwinCore React Native developers handle feature development, stabilization, and ongoing improvements. The work focuses on maintaining app reliability while supporting new releases and platform updates.
Modernizing Legacy React Projects
Older React projects often rely on outdated patterns, libraries, or fragmented state management. TwinCore developers help modernize these applications by introducing hooks, updating dependencies, and cleaning up technical debt without breaking existing functionality.
Performance Optimization
We improve your React app’s speed and responsiveness with lazy loading, memoization, and code splitting.
Performance-Sensitive React Applications
When frontend performance becomes a bottleneck, TwinCore developers address rendering issues, inefficient state handling, and data-heavy views. Optimization work is done carefully, with an emphasis on predictable behavior and long-term stability.
React Team Extension
TwinCore developers join existing teams and workflows instead of working as isolated contractors. Knowledge is shared, standards are followed, and delivery does not depend on a single individual being available at all times.
Why Choose Us for React Development
Finding React developers isn’t the problem - finding ones who can scale with your product is. We keep the hiring process short, transparent, and focused on technical fit, so you get people who write clean code and communicate clearly.
Proven Expertise
Our engineers have built and maintained React systems for SaaS platforms, fintech dashboards, and high-traffic eCommerce sites. They understand how to balance speed, maintainability, and UX under pressure.
Agile Development Process
Short sprints, frequent updates, direct contact — no layers between you and the team. We adapt to your workflow instead of forcing ours.
Flexible Engagement Models
Start with a single developer or an entire team. Scale up or down as project scope changes — no lock-ins, no overhead.
Code Quality & Security
Every pull request passes review and automated testing. Static analysis, E2E checks, and dependency monitoring keep the product stable and predictable as it grows.

Frequently Asked Questions
How fast can we start working with a React developer?
Onboarding takes up to 48 hours. Once the match is confirmed, the developer joins your tools, codebase, and workflow and starts working on real tasks almost immediately.
Who manages the developer day to day?
You do. Your PM, your tech lead, your priorities. The developer works as part of your team, while Twincore ensures continuity and support behind the scenes.
Will the developer work inside our existing codebase?
Yes. This setup is built specifically for existing products. The developer joins your codebase, understands the architecture, and contributes without disrupting what already works.
What level of React developers can we hire?
Mid, senior, or lead level depending on your needs. From feature development to refactoring, performance optimization, or owning a product area.
Can we integrate your React developers into our existing team?
Definitely. Whether you need one senior engineer or a full front-end squad, our developers integrate seamlessly into your workflows, standups, and codebases. We adapt to your toolchain — GitHub, Azure DevOps, Slack, or Jira — with minimal onboarding friction.
Are these developers freelancers or external contractors?
No. All developers are part of the Twincore team. We don’t source random profiles per request or outsource hiring to third parties.
How do you select a React developer for our project?
We match developers based on their level, technical stack, and hands-on experience with similar tasks or products. The goal is practical fit, not just checking boxes on a CV.
Is there a trial or verification period?
Yes. There is a 7-day verification period so you can evaluate how the developer works inside your team before fully committing.
What if the developer isn’t the right fit?
If the fit isn’t right during the verification period, we handle replacement without disrupting your delivery or restarting the process.
