Mentoring Freelance Platform
NDA
The key idea of the project was to allow Mentors find students, schedule different meetings with them using internal platform tools and receive different internal achievements, increase a level of mentoring etc. The second part of the application was to provide students with all necessary instruments to communicate and meet with mentors.
Responsibilities & achievements
This App was written in lit-html, LitElement and React + Apollo technologies, so the Graphql was in use to communicate between front-end and back-end, but the back-end was written in ASP.NET and it was maintained by internal client’s team, so I only worked on front-end. I love this project because there were quite interesting and atypical behaviors and features, and I learned a lot of new technologies here and I made all these things work in practice. For example this app was written in lit-html and LitElement and I rewrote it to React. It was quite an interesting experience to learn how these libraries look and how all the components were built on their base. Also I met a lot of web components and custom observing libraries here and I researched how all this stuff works before we migrated most parts of the app to React and Typescript. This was also the project where I practiced GraphQL and Apollo a lot: I built new queries, mutations and subscriptions, added paging and sorting and there were a lot of updates to existing schema.
Drink Tasting
NDA
This was an app build mostly for mobile for drink tasting. The app was build on Ionic with Express.js & MongoDB on the back-end and admin dashboard build on React.js.
Responsibilities & achievements
Firstly, the project was developed using Express.js (and Java for some modules) on the back-end and React/Angular/Typescript on the front-end. I love it because there were a lot of interesting and atypical behaviors and features, and things that I implemented and I brought were really valuable updates to the product. I learned a lot of new technologies here and I made all these things work in practice. For example, on the back-end, I integrated and interacted with Google Cloud SDK: basically migrated the file storage to the GCP storage, added a GCP vision, rewrote MongoDB queries into ElasticSearch queries, used an ElasticSearch library for automatic indexation and configured product recognition by a photo. Another example was around Mobile experience on this app. This is the project where I partially helped with Ionic, Cordova development (that was mostly about the UI/UX with minor functional updates. The most challenging part for me was to learn how to use the development migration tools but I figured it out and it ended up being a very valuable skill for me
