Hire the Best NativeScript Specialists
in Serbia

Welcome to my profile, Do you need a reliable React or React Native developer to turn your idea into a polished, high-performing product? You’re in the right place. I'm a professional JavaScript coder, Bachelor of Computer Applications. With over 6 years of experience in the game, I can guarantee that your project will be safe with me. I’ve worked for both startups and large companies using different scripting languages, frameworks, and libraries. Following TDD approach my code is always clean, pragmatic and testable. In my opinion, when building a digital product, communication and transparency rule. They are the key to success. So I constantly ask for feedback being attentive to detail and giving my suggestions. I follow the Agile methodology which allows being flexible, adjust to any changes during development and create just the thing as a result. My skills: React, React Native, JavaScript, TypeScript, jQuery, Redux, Zustand, GraphQL Feel free to contact me and let's build your project together.

I build production-grade cross-platform mobile apps and scalable web platforms — from MVP to enterprise. Clients hire me when they need someone who can own a feature end-to-end: mobile, backend, database, tests, and deployment. Mobile (iOS + Android): React Native, Expo, Ionic — full app store deployment, push notifications, offline-first, native modules. Frontend: Angular, React, TypeScript, Apollo Client, responsive UIs, component architecture that scales. Backend & APIs: Node.js, Supabase, Hasura, PostgreSQL, GraphQL, REST — real-time APIs, row-level security, auth flows, SQL performance tuning. Testing & Quality: Playwright (E2E), integration + unit tests, CI pipelines. I don’t ship code I can’t trust. DevOps: Docker, AWS, self-hosted VPS, TLS/certificates, CI/CD. Also experienced with: Java, Spring Boot, MySQL. I’ve worked inside large enterprise codebases where every change ripples through dozens of modules, and I’m equally comfortable greenfielding a product from zero. I understand what it takes to run a product, not just close tickets. Clear communication. Realistic estimates. Code you can hand to the next developer without shame. Available for long-term contracts or scoped projects. Tell me what you’re building.

I help businesses turn Mobile / React Native apps into stable, production-ready products — and extend them with practical AI features when it makes sense. Most mobile apps don’t fail because of missing features — they fail because of crashes, poor performance, and unreliable analytics. That’s where I come in. I work with teams that already have an app (or MVP) and need to: • Fix crashes and improve stability • Optimize performance (startup time, memory, smooth UI) • Implement or repair analytics (especially Firebase) • Deliver production-ready features that scale In addition to mobile development, I actively build and integrate AI features into real products — including chat-based assistants and Retrieval-Augmented Generation (RAG) systems. I work with both hosted and local models, focusing on choosing the right balance between performance, cost, and privacy depending on the use case. My focus is not just on making AI “work”, but on making it usable inside real applications — from UX design to backend logic and production deployment. What you can expect working with me: • Clean, maintainable code • Clear communication and fast turnaround • Focus on real-world results, not just code If your app feels slow, unstable, missing key insights — or you’re looking to add meaningful AI features — I can help you get it to production quality.
