  I'm responsible for developing Rent and Lend REST API. The API is PHP-based, with Lumen framework under the hood. The structure of server responses is standardised according to JsonAPI (https://jsonapi.org). Besides writing code, I'm also responsible for user's data administration. Some of the technologies/tool used: - MySQL - Pusher - JWT Auth - Google API - Facebook API - Elasticsearch - Web Pushes - PHP Unit One of the major architectural challenge was to develop an efficient and accurate way of handling user's inquiries. The whole mechanism bases on geolocation and it has to compare distances between users in real time. We use Great Circle Distance Algorithm to calculate the shortest distance between two points and Midpoint Circle Algorithm to determine points inside our space structures. Show less
