About this gig
I'm a full-stack developer specialized in React, Next.js, and Node.js with 6+ years of experience building production web apps for startups and scale-ups across Europe and the US. I've built onboarding funnels, dashboards, and SaaS interfaces at funded companies.
What I can build for you:
- React or Next.js applications from scratch
- Onboarding flows, dashboards, admin panels
- REST or GraphQL API integrations
- Performance-optimized, accessible UIs
- Unit and integration tests (Jest + RTL)
What I need to get started:
- 1. Design files (Figma or similar)
- 2. A specification or user stories
- 3. API documentation (if applicable)
Why clients choose me:
- I write clean, documented, TypeScript code that your team can maintain. I follow best practices and deliver on time.
Message me before ordering if you're unsure which package fits your project.

FAQ
Do I need to provide a design or can you work from a brief?
Ideally you provide Figma files or a reference site. If you don't have a design, I can work from a written brief and suggest a clean, modern layout. Just message me before ordering to discuss.
Will the code be clean and easy for my team to maintain?
Yes. I write TypeScript, follow component-based architecture, and document the code properly. Everything I deliver is production-ready and handoff-friendly.
Can you integrate with my existing backend or third-party APIs?
Absolutely. I have experience integrating REST and GraphQL APIs, authentication systems, payment gateways (Stripe), and CMS platforms. Share your API docs and we can discuss scope.
How do revisions work?
All packages include unlimited revisions. I work iteratively — I share progress early so we can align before the final delivery, avoiding surprises.
