NodeJs Portfolio

1. https://bitbucket.org/Loginsky/laravelandvue (Laravel + Blade Vs RESTful API +
VueJs)
In this example I demonstrated Laravel as backend and used two Apps for frontend,
first one is with Blade, the Next one is with VueJs. The application was given as test
task and finished successfully. It demonstrate shopping cart with managing products,
users and other things

2. https://bitbucket.org/lifeconstructor/myolx (ReactJs + Redux + RESTful API)
In this example, I describe Responsive Front End done with
“NodeJs+Gulp+Bootstrap+Sass+Less”. The idea was to make design mobile friendly,
to make sure it is working without page reload implementing “react-router” and having
global state using “Redux” so when app get extended and components become
complex it will help to reduce rendering.
Here I decided to use PHP RESTful API, which is fitting into CRUD actions for Categories
and Products. The choice is cos it’s simple, fast to do, has it’s own backend and not to
worry about MongoDB architecture for big data if needed.
Also there is a specific Redux architecture for this project-example using: “actions,
containers, reducers” (in “dev” directory) and there are interesting tools like
Immutable.Js providing a set of data structures that can help to solve certain
performance in the project.
To see it in action, please use README file on my bitbucket repository and you can
browse source code too
https://bitbucket.org/Loginsky/adminreactjs An other Project using ReactJs (frontend)
and Laravel backend developed for admiinistrating internal company system like Jira.

3. https://bitbucket.org/lifeconstructor/user-chat-meteor-react (MeteorJs + ReactJs)
This example show how to use ReactJs with MVC MeteorJs framework. Chat application
provide: registration, login, own portfolio, changing chat rooms and other.
I didn’t use any routing here, but I have one example-project where I use it with
Meteor
“MongoDB” is used to store data in the system and make MongoDB queries
To see it in action, please use README file on my bitbucket repository and you can
browse source code too
 4. https://bitbucket.org/lifeconstructor/koa (KoaJs + Stylus + Pud)
This example is showing how to use Koa.Js MVC framework, which is good alternative
to Express.Js, it is using “MongoDB” (there is an explanation in readme file, how to
migrate MongoDB database to other server), “Stylus” vs. Css and “Pud” vs. Html. The
main idea of the app to show how simple it is to create MVC Server side file structure
with “Koa.Js”, having “koa-router” for switching pages, change app language and all
page changes work very fast as expected from NodeJs web application. All code is
available from that repository.

5. React Native App (ReactJs/ReactNative)
Mobile app, for Android and iPhones using ReactNative, which is the child of ReactJs
technology. This was a big project started at the end of 2015 and lasted for 8 months
with a team of 7 people. I was Team Lead of 2 programmers and on tester. Then we
had PM and two testers on Client side. To be honest at that moment of time there were
not many (about 10) programmers in Lviv (my home town) who worked with that
technology. We developed the app for American Pharmacy market, providing it’s
customers with: discounts on medicaments, Pharmacy locator (using GMap) with
points and cheapest prices of the drug around *N miles, Reminders for prescriptions
and other services, Formulary search, Drug search. The app can be found by
“RxPreferred” name from GoogleStore (Android) and iTunes (IOS), it is very similar to
its competitor “GoodRx”.

About me
One of my directors in UK told me that I'm very diplomatic person. I came across different
industries and teams in various projects and for sure, I tried to be as reliable developer as
possible (in my project role).
I'm always trying to be a good producer and performer and of course a team player. My next
aim is to become Node.Js Senior developer after Senior PHP developer level.
