Developed and led the end-to-end implementation of a comprehensive online coaching platform designed for hypnotherapy and personal development professionals. Built a scalable web application that streamlines client onboarding, appointment scheduling, secure payments, video session management, and digital course delivery within a unified ecosystem. Architected both the front end and back end, integrated 3rd-party APIs, optimized performance, and implemented automation workflows to reduce administrative overhead. Collaborated closely with stakeholders to translate business requirements into a reliable, user-focused platform capable of supporting long-term growth and a seamless experience for both coaches and clients.

Fliday is a global travel eSIM platform that enables travelers to purchase and activate prepaid mobile data plans instantly in over 100 countries. The platform eliminates the need for physical SIM cards by providing seamless digital eSIM activation, allowing users to stay connected without expensive roaming charges. I led the full-stack development of the platform, designing and implementing scalable frontend and backend architecture, secure payment workflows, country-specific eSIM plan management, device compatibility validation, and automated eSIM delivery. I also built responsive user interfaces, optimized application performance, integrated third-party APIs, and developed a comprehensive admin system for managing products, destinations, orders, and customer operations. The solution was engineered with a strong focus on scalability, security, and delivering a fast, intuitive purchasing experience for international travelers.

Developed a comprehensive healthcare platform designed to connect patients with healthcare practitioners through a structured, user-focused digital experience. The platform brings together practitioner discovery, specialty-based browsing, search, location-based filtering, map and list views, detailed practitioner profiles, and patient-oriented workflows within a single application. It also includes practitioner onboarding, profile management, patient connections, analytics-oriented functionality, professional content, and community experiences. I contributed to transforming complex healthcare requirements into an intuitive and scalable product structure, focusing on clear user journeys for both patients and practitioners. My work involved building responsive interfaces, reusable application components, structured data-driven experiences, and integration-ready workflows. The project required careful attention to usability, information architecture, performance, and maintainability because users need to navigate sensitive and information-heavy healthcare experiences quickly and confidently.

Developed a premium hospitality and accommodation experience for Marinali Rooms in Bassano del Grappa, Italy. The platform presents historic suites through high-quality visual storytelling, detailed accommodation information, multilingual navigation, guest-focused booking interactions, and direct availability workflows. The experience combines heritage storytelling with modern hospitality functionality, allowing users to explore individual suites, review property details, view image galleries, and proceed toward booking. I focused on creating a polished responsive interface, clear information architecture, intuitive accommodation discovery, and a conversion-oriented booking journey while maintaining the visual identity and premium positioning of the property.

Developed a multi-feature sports platform designed around the handball community, bringing together player discovery, courts, tournaments, events, rankings, sports content, videos, and commerce within a unified digital experience. Because the product combines several distinct functionality areas, a major focus was on creating a clear information architecture that allows users to move naturally between community, sports, event, and commercial experiences. I worked on responsive interfaces, structured discovery workflows, content presentation, event-oriented experiences, player and sports information, and commerce-related sections. The project required designing reusable components and consistent interaction patterns across multiple product areas while maintaining a cohesive visual experience. This work demonstrates my ability to approach a platform as a complete product ecosystem rather than treating each page or feature as an isolated implementation.

Developed an interactive browser-based image processing application that allows users to upload images, apply different artistic and visual transformations, adjust image parameters, preview results, and export processed images. Unlike a traditional content or marketing website, the project required application-level functionality with interactive processing workflows and immediate visual feedback. I worked on the interface architecture, image upload experience, transformation controls, effect configuration, preview interactions, responsive behavior, and export workflow. The application includes multiple visual treatment concepts and provides users with direct control over how their images are transformed. A major focus was creating an intuitive, creative tool experience while keeping the underlying application structure maintainable and responsive. This project demonstrates my ability to build interactive software products where front-end logic, browser capabilities, visual processing, state management, and user experience need to work together seamlessly.
