I turn ideas into powerful solutions.

What I Focus On

Full-stack developer focused on real production systems and business logic.

About Me

I build reservation and ticketing platforms for transport, hospitality, and service businesses.

Need a booking system?

Passengers search available routes by origin, destination, and date. The system returns departures with real-time seat availability.

Interactive seat maps show available, reserved, and blocked seats. Selected seats are temporarily locked to prevent double-booking.

Passenger details, payment processing, and automatic fiscal-receipt generation for legal compliance.

The system generates a ticket with a unique QR code. Passengers receive confirmation by email.

Field workers scan QR codes with a mobile app to validate tickets at boarding. Works offline with background sync.

Staff manage departures, view passenger manifests, track revenue, and export reports from a role-based admin panel.

System Architecture

Passenger selects origin, destination, and date. The system returns available departures with pricing.

Interactive seat map shows available and taken seats. Selected seats are temporarily locked to prevent double-booking.

Name, contact, and any required travel documents are entered and validated.

Online payment is processed. A fiscal receipt is generated automatically to comply with Serbian tax regulations.

The system generates a ticket with a unique QR code. Confirmation is sent by email.

Field worker scans the QR code with the mobile app. Ticket is validated and the passenger manifest updates in real time.

The Booking Flow

The Challenge

I build reservation, ticketing, and operations platforms for transport and service businesses.

Need a similar system?

Open the live demos below — no login required. The passenger demo shows the booking flow, the admin demo shows the operations dashboard.

Try It Yourself

Passengers search routes, view real-time seat availability on interactive seat maps, and complete reservations through a guided checkout flow.

Online Seat Reservation

Each ticket carries a unique QR code. Field workers use the React Native app to scan and validate tickets at boarding, replacing paper manifests.

QR-Code Ticket Validation

Every payment automatically generates a legally compliant fiscal receipt, meeting Serbian tax authority requirements. The integration handles receipt numbering, tax calculation, and regulatory reporting.

Fiscal-Receipt Integration

Admin users define routes with stops, set departure schedules, manage pricing, and track occupancy across departures.

Route & Departure Management

Four access levels — operators handle daily bookings, dispatchers manage departures, managers view reports, and super-admins configure the system.

Role-Based Admin Panel

Daily, weekly, and monthly reports covering revenue, passenger counts, route performance, and occupancy rates. Exportable to CSV and Excel.

Operational Reporting

Key Features

Laravel with MySQL. Resource controllers with form request validation, service classes for business logic, and repository pattern for data access. Redis handles session storage, caching of route and departure lookups, and rate limiting. Queued jobs process payment confirmations, fiscal receipt generation, and email notifications in the background.

Backend

A React SPA that guides passengers through route search, departure selection, seat picking, passenger details, and checkout. Connected to the backend via REST API with real-time seat availability.

Passenger Frontend

A React admin application with role-based access control. Operators manage routes, departures, passengers, and pricing. Managers access revenue reports, occupancy data, and CSV/Excel exports. Super-admins configure system settings and user permissions.

Admin Panel

React Native (Expo) app for field workers — primarily ticket validation via QR code scanning. Works with intermittent connectivity through offline-first data caching and background sync.

Mobile Tools

Dockerized deployment on DigitalOcean. Nginx reverse proxy, automated SSL, and environment-based configuration for staging and production.

WordPress Websites

From first line of code to post-launch support — everything your business needs in one place.

End-to-end development services

I scope problems clearly and direct AI tools deliberately — the same way I'd brief a teammate, with explicit constraints and intent.

Precise prompting

Every change is read, understood and reviewed before it ships. AI speeds up exploration; it doesn't get a free pass into production.

Disciplined code review

The result is quicker delivery with clean, maintainable, reviewable code — not throwaway output that someone has to rewrite later.

Faster, reviewable shipping

Generated code is verified against real behavior and covered by tests before it reaches users. Nothing ships unproven.

Verification & testing

I use AI tools to move faster on development, refactoring, debugging and documentation. Architecture, business logic, validation and final code quality stay under my control — AI speeds up the work, it doesn't decide what ships.

AI-accelerated development with senior engineering judgment

I'm available for backend development projects — from building new APIs to extending existing Laravel systems.

Need a Laravel backend?

I start with the data model — migrations, relationships, and indexes — before writing a single controller. Getting the schema right avoids expensive rewrites later.

Database-first design

Resource controllers with form request validation, consistent JSON responses, and proper HTTP status codes. Every endpoint is documented and testable.

API design

Complex logic lives in service classes, not controllers. This keeps controllers thin and business rules testable and reusable.

Business logic in services

Redis caching for hot paths, queued jobs for heavy processing, proper error handling, and environment-based configuration. Ready for staging and production from day one.

Production readiness

How I Work

Built With Laravel

Production-grade APIs, business logic, and data models — built to handle real transaction loads.

Laravel Backend Development

Tell me what you need — within 48 hours you get a fixed quote and a phased delivery plan.

Ready for an exact quote?

The number of pages and features is the biggest factor — bookings, payments and admin panels take more work than a brochure site.

Scope of functionality

A theme adapted to your brand is faster and cheaper; design from scratch gives a unique look but costs more.

Custom design vs. theme

Card payments, fiscal receipts, couriers, booking channels (Booking.com/Airbnb) — each integration adds scope.

Integrations

A site in two or three languages means more content and per-language SEO setup (hreflang, translations, localization).

Multiple languages

If your texts and photos are ready, you save time and money. I can help with structure and copywriting.

Content readiness

Standard timelines are included in the price. Rush delivery is possible for a surcharge when the schedule allows.

Deadlines

So you know upfront where the budget goes — no surprises in the quote.

What drives the price?

Pricing FAQ

After launch you're not on your own. A monthly plan covers updates, backups, monitoring and small changes — the site stays fast, secure and up to date.

Maintenance & support

WordPress or a modern static site for companies that need a serious online presence.

Business website

A booking system for apartments, tours, transport or services — guests book online, you manage everything from a panel.

Booking website
