Hello,
With your project's goal of creating an engaging WebAR scavenger hunt, my technical skills in web and mobile development, particularly with Vue.js/jQuery + Laravel/Yii2/Symfony + REST/GraphQL/Websockets, perfectly align with your needs. The combination of PHP 5 / 7 / 8, Yii/Yii2, Laravel, Slim 3, and Symfony have empowered me to build complex multitier applications and handle WebSocket-based functionalities adeptly - essential as this leads to precise geolocation pairing for the art pieces placement.
I understand the importance of a clean UI and user-friendly features in ensuring an enjoyable UX. With experience in front-end and back-end development using JavaScript, NodeJS/Python/C (C++ not included), HTML5/CSS and sophisticated databases like MySQL, Oracle, PostgreSQL,and NoSQL (MongoDB/Redis/MongoDB), I guarantee the seamless cross-platform compatibility your project demands.
Additionally, I will bring a wealth of experience in building game logic, using Content Management Systems for easy tracking and updating of core elements as well as enabling social interactions- giving users the opportunity to express their enthusiasm on art pieces discovered. My focus is always on quality, satisfaction and reliability which dovetails well into the gamification strategy planned here. Looking forward to completing your vision.
