StreetBite / FoodTrucker (2019 - 2021)
React, MongoDB, ExpressJS, Webflow, Custom Authorization, Mapbox, Algolia, Complex Map Interactions
Street Bite is an ambitious project built for a client who needed a way to aggregate street-food vendors in the wide London area. I have dealt with the front-end development and created a fully functional web application. The users can look up vendors either by searching for a specific food/cuisine or by browsing the interactive map and selecting their market of choice. Administrator could add new vendors, edit existing ones, and manage the whole platform and it's users.
Client Review:
"Milutin designed and implemented the entire front end of a rather complex dynamic web application in React. That included integration with mapbox to dynamically show food markets on a map, -not so simple- search using algolia that involved searching in location + time + string query at the same time, users signup & signin, dynamic UI panels, image galeries and flows to suggest improvements. This was a large volume of work and a rather unconventional and challenging UI fro a front end engineer but he is always able to execute flawlessly. The entire process felt effortless since his collaboration with back end was super smooth. He can reason through problems very well, is great at communication and is always happy to explain the whys and hows behind his proposed implementation as well as further improvements that I did not even ask for but are always great additions to the solution."
Mediaset Platform (2020 - 2021)
Over the course of approximately 6 months I collaborated with several developers on integrating new features into the already existing and live platform. It had already been live and has had a huge user base in Italy (19.6 million unique users per month, and 225 million page views per month) which makes this the biggest platform I've worked on in 2020. I was included in daily standups, communication with the whole team and all my responsibilities and tasks were well defined on Jira and Confluence. The codebase was initially a bit outdated and it used some obsolete standards and functions, so alongside creating and implementing new features a lot of refactoring was done.
TrainedIn Platform (2019 - 2020)
TrainedIn was one of the most significant MERN stack projects I've ever taken part in. I had the responsibility of delivering a fully functional platform that was fully responsive on all devices. TrainedIn is a web-based platform for connecting training providers with consumers interested in enrolling into courses or applying for teaching jobs. I've decided to go with ReactJS, Redux and Bootstrap libraries as core libraries for this platform. Over the course of three months and a half months, I followed the Agile Scrum Methodology of development and delivered frontend part of platform successfully.
UpTask (2019 - 2020)
UpTask is a web and mobile platform intended for use by managers to help organize their staff. The features this web app offers are created in great detail to help managers have full control over the workload and employees. I've used ReactJS for frontend development, as well as some specific libraries like "react-beautiful-dnd" for creating easier task management system and tools like Mapbox for tracking users on map in real-time.
EyeRate App (2019)
The client needed a new MERN Stack Application that will have functionalities as the already existing iOS App that was outsourced to another group of freelancers. My responsibilities for this project are making a full UI/UX optimized app that communicates and displays the data fetched from the backend. This App is entirely made out of ReactJS and ReduxJS. The target audience for this App is business owners who are looking to improve their business through communication with their clients and seeing their reviews and responses throughout the App. This App communicates with the REST backend, which is returning JSON data format that App uses for visualizing data to the business owner. Some of the main features are sending messages through Twilio API services, visualization of data, authorization, changing profile info such as email, password, and avatar. This project is currently published on the AWS EC2 instance.
