The goal for this project was to:

• Build a website from scratch on Drupal 7.
• Migrate all content from the custom CMS previously used for this website.
• Build search pages with Apache Solr.
• Use SSO employed on other HIMSS websites.

Back-end technologies: Drupal 7, Acquia, SSO, and Apache Solr.

Front-end technologies: jQuery and Less.

Yonder suggests accommodation in nature-rich locations in all shapes and sizes, including guesthouses, cottages, barns, and more. They are aggregated from multiple services and can be booked via a web app.

I was working on third-party services synchronization, setting up Elasticsearch to build a rich search experience and a React-driven web app.

As a restaurant owner, you can manage restaurant menus, furniture, and rooms with real forms and sizes on canvas using this service.

The service works as an event managing canvas app: you arrange the chosen room with tables of different forms and sizes, place diners, provide them with food from menus, and much more.

I designed the Firebase database schema, which wasn’t done at all, and moved the project from a custom Node.js web server to Firebase hosting. I set up Firebase cloud functions (Node.js) to keep the app logic on the Firebase side.

I set up a custom Express.js server that integrated with Firebase and was able to deliver DB updates and fully refactored almost all the AngularJS parts of the code, including Fabric.js canvas “sub-applications” (two of the most important and biggest parts).

I set up the deployment processes and created tasks delivering workflow.

Technology stack: Node.js (Express.js web server), Firebase (hosting, database, cloud functions, Admin SDK, and Node.js), AngularJS (Triangular), and Fabric.js.

This is a dating iOS app with deep integration with Facebook and "coaching" system to manage user profiles. This application creates a user profile of certain type basing on gender and sex interests: each profile type has its own fields and privileges in the app.

The user logs into the app via Facebook. A huge part of user data is retrieved from Facebook and keeps up-to-date. Once a profile is created, it waits for "coach" approval. Coaches are special users who manage the app, approving profiles and helping users create better profiles.

In this app, straight female users can perform a search with lots of filters: age, location with distance in miles, body type, education, religion and many others. Then women can like/dislike men from search results. Men can respond in chat if they like her profile or reject her if they don't.

The app's back-end runs on Node.js with RethinkDB for DB. All data changes in RethinkDB are synchronized with extra DB on Firebase. Firebase DB is used for faster read access to data on the mobile app (including chat messages). The mobile app is built with React Native with MobX used for state management.

This dashboard allows for using assets directly in Adobe Creative Suite. I built several tools for image edition and tagging for subsequent search in Adobe programs.

Technology stack: AngularJS, Node.js, Node-webkit, Sencha JS Ext3/Ext4, Adobe AIR, Protractor

A React Native mobile app developed for task tracking that has a Meteor-based back-end.

I mainly completed the mobile app and designed and developed push notifications system from scratch. The requirement was to make fewer changes in the Meteor back-end as it is shared with the web app, so the solution was to integrate Meteor and the mobile app with a Firebase database to store user tokens and push notification data there. Then PNs were sent using Firebase cloud functions via Firebase notifications API.

Technology stack: Meteor, AngularJS, React Native

Online work platform where parents can find a sitter for their child for a short time segment and babysitters can search for a job. Parents registered on the site can fill a private sitter hub with favorite babysitters and create a job for selected sitters from a custom view. The application allows parents to gracefully manage all workflow from creating a job to making payments. Integration with Twilio SMS web service lets users invite sitters to a job, accept/decline job invitations, and post a new job by mobile phone.

Front-end technologies: AngularJS, Bootstrap, Less, NPM, Bower, Gulp
