Case Studies.

Zewardy is my first monetization app — I built it from scratch as an ITLIGHT proprietary product. The main challenge was launching a full ecosystem: ad network integrations, a rewards system, and basic protection against bots and emulators.

I designed and built the full stack: a Flutter app with AdMediation integration, Firebase backend, and a basic Anti-Fraud module detecting emulators and VPN traffic.

Earnrly is a modern, lighter evolution of the Zewardy concept — redesigned from scratch on a more robust stack (Laravel + MySQL instead of Firebase). The challenge was building an advanced Anti-Fraud system that effectively blocks bots and fraudulent traffic from advertisers.

I designed everything on a new stack: MySQL as the database, Laravel as the API, Flutter as the mobile client. I built an advanced Anti-Fraud engine based on anomaly detection, postback verification, and user behavior pattern analysis.

I conceived and built a SaaS platform for psychologists and therapy clinics from scratch. The key challenge was a complex Multi-Tenant model and integrating payments directly between patient and therapist without an intermediary.

I designed the Multi-Tenant architecture, integrated Stripe Connect for automated settlements, built an interactive booking calendar, and an in-browser video consultation module.

I built my own web tool for fast B2B lead acquisition, verification, and cleaning. The gap in the market was the lack of a simple tool combining data extraction, validation, and CRM export in one place.

I built the web app from scratch (Next.js + Laravel API) with a domain and mailbox verification algorithm, automatic deduplication, and clean lead export ready for CRM import.

The client needed a modern mobile app for earning money by completing tasks, working across all mobile platforms.

I built a cross-platform Flutter application with an intuitive user interface, a task management system, and secure payment processing.

The fintech startup needed a modern landing page and web application frontend for their investment platform.

Created a responsive landing page using Astro and a web application frontend in Flutter Web featuring a modern user interface.

The client needed an advanced mobile application for searching and posting apartment listings with a smart recommendation system.

A complete Flutter application was developed with custom search algorithm, built-in helper chat, and admin panel for managing listings.

The client needed a Cameo-style platform in Poland — enabling users to order personalized videos, book meetings and online lessons, and paid chat with creators.

Designed and implemented a comprehensive Flutter Web platform with Stripe payments (BLIK, credit card, PayPal), Google Meet integration, creator and admin panels, and gift card system.

The existing messaging application required regular updates and implementation of new features.

Implemented a series of Flutter application updates, improving the user interface and adding new features according to project needs.
