Mobile & Web Developer • UI/UX Design
I'm Viktor — a developer and designer from Belgrade. For five years I've designed and shipped production software across healthcare, logistics, and hospitality — websites, mobile apps, and the backends behind them. I cover the full picture: UI/UX design, frontend, backend, deployment, and SEO. One person, no handoff friction, no agency overhead. I also use AI tooling where it makes the work faster and better — with 5+ years of experience deciding where to trust it.
5+ years of production code across web, mobile, and backend. I design and build complete products — from the first wireframe to the production release. Every project gets my direct attention.
What that means for you: clean design, fast delivery, and code you can actually maintain.
Production experience across web, mobile, design, and cloud.
Design first. Build fast. Ship reliably.
Every project starts with structure and visuals — wireframes, UI design, and a clickable prototype, so you see the product before a single line of code is written.
I design the architecture, data models, and security rules, then build on a modern stack. This is where 5+ years of production experience matters most — every trade-off is deliberate.
Automated tests, CI/CD pipelines, and monitoring. Your product goes live smoothly — and stays stable after launch.
Varius
Leading mobile and full-stack development on complex client projects — owning architecture, design decisions, and client-facing delivery.
Varius
Built and maintained production mobile and web applications for clients across multiple industries. Grew from mid to senior level — owning architecture decisions and client-facing delivery.
Freelance — Top D&D (Vienna)

Freelance — Gentlemen Transport
Two Flutter apps (passenger + driver) with Google Maps live tracking, WSPay in-app payments, Directions API routing, and a Next.js admin panel — shipped from zero to live on App Store & Play Store.
Freelance — E-commerce & Web Projects
Built e-commerce stores and business websites for local clients using Laravel, PHP, and WordPress. First production client work — establishing the foundation before joining a full-time team.
I specialize in Flutter/Dart for cross-platform mobile apps and React/Next.js for web. I've shipped production apps for clients in Canada, Austria, Cyprus, and Serbia — across healthcare, logistics, fintech, and facility management. I also handle the design side — UI/UX, responsive layouts, and interfaces that stay consistent with your brand.
Yes — I design the interfaces I build: wireframes, UI design, responsive layouts, and the visual identity of the site. Design and development in one place means faster iterations and no handoff friction.
Yes — technical SEO is part of every website I build: site structure, performance, metadata, sitemaps, and analytics (Google Tag Manager, Google Business). For Bridal Makeup Cyprus I took a brand-new site from zero to Google-indexed in under two weeks, in four languages.
I use modern tooling, including AI assistants, for the mechanical parts of coding — boilerplate, documentation, and test generation. It speeds up delivery; it doesn't make decisions. Architecture, design, and business logic are mine, backed by 5+ years of production experience.
Yes — I've delivered projects for clients in Canada, Austria, Cyprus, and across Southeast Europe. Remote collaboration is my default: async communication, clear documentation, and regular progress updates so there are never any surprises.
Selective. I focus on substantial technical work where I can deliver measurable impact. My primary focus is building strong long-term engineering work.
I write clean, well-documented code with clear separation of concerns. Every project I ship is structured so the next developer can pick it up without issues. I prioritize long-term maintainability over clever shortcuts.
