You will get a responsive web app or dashboard in React / Next.js
Project details
I'll build you a fast, responsive website or web app in React and Next.js, from a single
landing page to a full product with its own API, database and admin dashboard.
You get clean, maintainable code, a mobile-first responsive layout, sensible on-page SEO,
and the site deployed and live, not just handed over as files. If you already have a
codebase, I match how it's written instead of rewriting it.
What I can build:
• Landing pages, marketing sites and multi-page websites
• Web apps, dashboards, admin panels and internal tools
• A backend with REST or GraphQL APIs, auth, and a database (PostgreSQL, MongoDB, Firebase)
• Integrations: Stripe payments, third party APIs, CMS, email, analytics
I've built platforms like KIMISUITE (a modular business platform), ORIGINEWS (a content
marketplace) and PlayHunch (a UK sports platform), so larger, real products are normal for me.
Not sure which tier fits? Message me first with what you need and I'll point you to the
right one, or set up a custom offer. Happy to do a small paid task first so you can see the
quality before committing.

About Nikolche
Full-Stack Web & Mobile App Developer | React, Node, Flutter
Bitola, North Macedonia - 5:55 am local time
⚡ AI speed plus 6 years of production experience, so the code ships fast, feels premium, and scales without cracking.
🛠️ Specializing in Web & Mobile App Development | Flutter, React, Node | iOS and Android
🌍 Building for EU and US clients since 2020. Fluent English, flexible across time zones.
📅 Available for 1 to 2 new projects this month.
I build full products end to end, from the idea to the live app: backend, frontend, database, cloud and the security around it. I can start something from scratch or jump into an existing codebase and match how it's already written, without breaking what works.
Some of what I've built:
- KIMISUITE, a modular SaaS business platform where companies plug in the apps they need (CRM, invoicing, bookings) and it all runs as one system
- PlayHunch, a UK sports prediction platform on web, iOS and Android, regulated by the UK Gambling Commission
- Uncouth, a virtual dermatology and telehealth service in the UK
- ORIGINEWS, a journalism content marketplace with automatic translation built in
- Transit Ringas, a public transport safety reporting app in South Africa, live on Google Play
- A secure e-voting app for a city council, and a real-time city bus tracker
I've worked across sports and betting, healthcare and telehealth, media and publishing, government, transport and SaaS, so I learn a new domain fast and ask the right questions early.
⭐ What a client said:
"The Cpay payment integration on my Wix site was completed extremely quickly and
professionally, delivered even before the deadline, with clear communication and
attention to detail. Everything worked perfectly and the experience was smooth and
stress-free. I highly recommend this freelancer."
— Antonio V., Nutritionist / Dietitian Consultant (Upwork verified review, March 2026)
With 6 years building production apps, I've shipped across iOS and Android with Flutter and native code, plus full web and cloud work. My strength is turning an idea into a real product and owning the whole stack: the user interface, the backend, the database, the deployment and the security. Fewer handoffs, fewer things that fall through the cracks.
I'm comfortable working solo or as part of a team, on a tight deadline or a long build. I've taken MVPs from a blank repo to the app stores, and I've joined existing products to extend and stabilize them. I've worked with early startups and with established businesses that needed to scale.
🌟 Why work with me:
- Communication: I reply fast and keep you updated, no silent weeks.
- Reliability: I treat your deadline and your budget like they're my own.
- Quality where it counts: I use AI tools to move fast, but I review auth, payments and security by hand, because that's where apps actually break.
- Ownership: you get clean, maintainable code and you own all of it.
😁 Let's talk. We can start with a free 30 minute call to map out the scope, the timeline and a clear price. If you'd rather de-risk it, we can start with a small paid first task so you see the quality before committing to anything bigger.
