Flutter & Full-Stack Developer
Shipping 40% Faster
I ship production software 40% faster by combining 5 years of hands-on expertise with AI-assisted development workflows. I know exactly where AI accelerates development — and where it doesn't.
Viktor Jovanović
Flutter & Full-Stack Developer | AI Automation Specialist
5+ years of production code, written before AI tools existed — so I understand code deeply enough to spot when AI misses the mark. I use AI as a tool to speed up delivery, not as a shortcut. Every project gets my direct attention.
What that means for you: faster delivery, lower cost, and code you can actually maintain.
Engineering Quality, Accelerated by AI
I'm Viktor — a senior full-stack engineer from Belgrade. For five years I've built and shipped production software across healthcare, logistics, and hospitality. I got fluent in AI-assisted development early (Claude, Cursor, GPT-4) and now ship features 40-60% faster than traditional workflows — without compromising architecture or production stability. Currently open to roles where AI-native development is a competitive advantage.

Featured Work & Solutions
Real-world systems built for performance, security, and scale.
Zlatiborac — Modernization of logistics system
Challenge
Zlatiborac's warehouse operations ran on a legacy Java application that could no longer be extended or adapted to new business needs. But shutting the system down for a full rewrite wasn't an option — it's critical infrastructure running every shift, every day.
Solution
Built a new Flutter application from scratch that connects directly to the existing Java backend's production databases. The legacy system stays untouched and live, warehouse workers get a modern tablet interface on top of it. Fully offline-capable, deployed on Samsung Galaxy Tab A9 devices across all workstations. Delivered in 11 phases with zero disruption to live operations. Used AI-assisted migration workflows to translate Java business logic into Dart while preserving the behavior of the original system.
QuatuorMD — Medical Health Platform
Challenge
A Canadian medical clinic needed a secure patient portal to track metabolic health — with medical-grade security and no reliance on third-party services for sensitive data.
Solution
I developed a Flutter app with a custom AWS backend to keep sensitive patient data within the clinic's private infrastructure. I implemented secure MFA login and a real-time health dashboard, delivering the full system on schedule and within the original budget.
S&I Cleaning — Workforce Management Platform
Maintained and extended a full multi-part platform: Flutter mobile app for field workers, Laravel REST API, and Next.js admin panel on AWS. Built new features for accurate time tracking, shift scheduling, and operational oversight — all synced in real time across locations.
Top D&D — Cleaner Operations App
Cross-platform Flutter app with QR code + GPS clock-in, assigned task management, photo upload on task completion, and real-time admin chat. Improved accountability and communication across all sites.
Zlatiborac Magacioner — Warehouse App
Built the Flutter warehouse app from scratch, tailored for dedicated Android devices. Established the entire mobile foundation for future internal tools across the Zlatiborac group.
Gentlemen Transport — Ride Booking Platform
Built two Flutter apps (passenger + driver) and a Next.js admin panel. In-app WSPay payments, Google Maps live tracking, Directions API routing, and Firebase real-time sync — all from zero.
Bridal Makeup Cyprus — React Website & SEO
Fully responsive React website, complete SEO setup, Google Business integration, Google Tag Manager, and 4-language support. Deployed and Google-indexed in under 2 weeks.
Uzmi Kredit — Credit Comparison Platform
Built a cross-platform app from scratch that aggregates credit offers from multiple regional banks and lets users pick the best deal — available on Android, iOS, Web, and MacOS.
AI-Native Development
Spec → Scaffold
AI-assistedClaude and Cursor turn specs into skeleton implementations in hours, not days. Boilerplate, structure, and initial test coverage — handled.
Architecture → Logic
Human-ledI design the system architecture, data models, and security rules. This is where 5+ years of production experience matters most — knowing when to trust AI output and when to override it.
Test → Deploy
HybridAI helps me generate tests and observability code, supporting reliable production deployments.
AI makes me faster. Experience makes me trustworthy.
