Hi! I am Lilia and I am a Learning Dollars software engineer. I specialize in Python and JavaScript development. And, I have done projects in various fields like a teacher student marketplace, AWS infrastructure management, a javascript AST code parser in a continuous integration system, and visual novels.

My first demo is Strumclub, a website that connects music teachers with students.

For Strumclub development I used a React frontend with a Django REST Framework backend. The two are connected by API calls using fetch in the frontend. I created the following features:

• a user authentication system that includes signup, login, and reset password pages
• a “teachers sorting” system according to the type of instrument. You can choose an instrument on the start page or on the ‘Teachers’ page
• if you click the ‘See profile’ button you’ll see profile of a particular teacher
• each teacher has the ability to сhange his/her personal data such as name, photo, instrument, availability, etc.

My second demo is a visual novel “The gift of Cthulhu”.

For creating this game I used the Ren’py engine that was written in Python. First I created and customized the graphical user interface. The main interactive elements used in the game are choice buttons and dialogues. There are several main storylines in the game and more than one ending. At the same time, the logic of the game is quite simple, the development of the plot depends only on the choice of the player which is made by clicking on one of the buttons in the displayed menu. The player can also save and load the game and change the options such as the speed with which text appears, sound volume and other parameters.

Thank you for watching my demos and I look forward to working with you!

Hi! I am Lauro and I am a Learning Dollars software engineer. I specialize in Server and Mobile App Development with Python, ReactJS, and React Native. I have done projects in mobile app development and back-end RESTful server development. I’m deeply interested in meditation, exercising and reading, and these three activities are a consistent part of my daily routine.

My first demo is the mobile app SangeetaSudha, focused on presenting server data to the final user. The stages involved in the development of the app were:

1. design of a new backend server with RESTful API based on Django REST framework to store and display the website information. It has different filter functionalities based on query parameters and screen names, all received from the mobile app.
2. development of a web crawler to download the information from http://www.sangeetasudha.org and save it in the new development server. The crawler logs the information on the terminal to keep the user informed of the progress of the crawling. In addition to that, it logs all errors and warnings on a different file following a standardized, which facilitates the later treatment of the errors and warnings.
3. development of the mobile app to fetch information from the new server and display it to the user in different screens.

My second demo is my personal website, lauromuller.co, developed based on WordPress and customized with HTML, CSS, and Javascript. The website is hosted in AWS, giving it flexibility and scalability for future improvements. This is a simple project form the programming perspective, but it strongly highlights my approach towards design and UX. The main characteristics of the project are:

1. Design customization, using both HTML and CSS, to make the website look cleaner and more attractive.
2. Design and create the content for the project management and business plan courses (still ongoing), and implement navigation menus to make website interaction easier.

Thank you for watching my demos and I look forward to working with you!

Hi! I am Pavel and I am a Learning Dollars software engineer. I specialize in developing applications for mobile and web platforms. I have done projects in e-commerce, CRM, and automation.

My first demo is CRM.

This is a deeply customized version of an open source application called SugarCRM. It was used by a company with 15 operators calling potential customers and returning clients. After several years of work, the size of the database increased to hundreds of thousands of records and searching became too slow. More than 30 seconds was required to search in a worst case.

The application’s database was implemented in MySQL using about a hundred tables with many relations and indexes. It had PHP backend and HTML frontend. I worked on the server backend. I implemented caching of a sophisticated data model in a plain key-value database that allowed to reduce the search time to 2 seconds. I used Mongo database. Thereafter, the search time did not increase even when the database became 5 times bigger. The client was fully satisfied.

Let’s check another demo.

It is an application for iOS and Android allowing users to sell or buy various services.

I used the React Native framework for a mobile client. Also, I used the Django framework for the backend. The application uses external login via Facebook, the device’s camera for taking selfies, and Amazon storage for uploading photos.

I will never stop wondering how well put together these frameworks are! They allowed me to quickly and reliably create native-looking mobile applications for both platforms using the same code base. I really like it.

Hi! I am Nutan and I am a Learning Dollars software engineer. I specialize in Web design and development. I have done projects in WordPress, HTML, CSS, JavaScript, PHP and mySQL. I’m personally interested in meditation, jogging, cooking and watching American TV shows. These activities are a part of my daily routine.

My first demo is a Food blogging website created using WordPress. It is mainly focused on displaying my personal recipes with some tips.

I have chosen a food blogging theme named Wisteria. This is my home page designed using a plugin named elementor. And on the right side you can see all the latest recipes. And I have divided all the recipes into different categories here.

If you click on one of the recipes, here you can see a recipe card. I have designed this recipe card using a plugin called Wp ultimate recipe. You can also print this recipe over here. If you change the servings over here, the ingredients will change according to the servings.

My second demo is an ecommerce website created using WordPress. It is mainly focused on easy interface to sell products online to your ideal customers.

I have used an ecommerce theme named storevilla for this website. I have used a plugin named woocommerce. It is an ecommerce toolkit that helps you sell products online.

This website provides all the functionalities such as add to cart, add to wishlist etc. You can see a product in the wishlist. Here you can also add to cart.

Thank you so much for watching my demos and I look forward to working with you!

Hi! I am Srinivas, a Java engineer who specializes in J2EE, Web Services, Spring, Hibernate, Progress BPM, Reporting tools like ESpreadsheet, BirtViewer and UI frameworks like Jquery, JSF, and bootstrap. I have recently started working on projects using python, nodeJS and React JS. I have done projects in the domains of healthcare, finance, and utilities. Outside work, I’m deeply interested in reading fiction novels, watching movies and short films, and knowing about various mythological facts.

My first demo is an Airline E-Ticketing System. This system is being used for booking domestic flights within Nepal for Dev Travel and Tours Pvt Ltd. Stated below are few features of the system that i will be covering as part of the demo.

1. Flight Search Page where in a user can select Fly From and Fly To airport points within nepal by selecting trip type as One Way / Round Trip and other respective parameters. On click of the submit button all the input parameters are being sent as part of a SOAP call against a remote server which returns the response containing the flight search results.
2. Flight Search Results page where in a user can check the respective flights based on Price Range and/or Refundable/Non-Refundable parameters before booking the respective flight. On click of the submit button all the selected parameters are being sent as part of a SOAP call against a remote server which returns the response pertaining to Flight Booking.
3. Flight Booking page where in a user can provide all the details pertaining to passengers who are travelling along with contact details like email address and phone number to which PNR details can be sent from the system after the payment has been done. On click of the submit button all the input parameters are being sent as part of a SOAP call against the remote server which returns the response pertaining to Payment.
4. Payment Page where in a user can pay the Fare price through Net Banking / Credit /Debit Card whichever is applicable. Once the payment has been completed successfully, flight itinerary is generated with all the details.

My second demo is regarding a JSX parser I worked on. This parser is used to validate wiki rules pertaining to JSX elements (HTML DOM elements) that were defined for a webapp boilerplate system. Notice how when I run the parser in terminal it breaks down the target file into its AST tree, and then it recursively walks through the tree checking that style rules are being followed or not. Stated below are high level steps as part of the parser.

1. Get the Abstract Syntax Tree (AST) from each of the input file (for example : index.js files from boilerplate system webapp components). To perform this operation I use the flow-parser nodejs module.
2. Iterate through all the JSX elements and validate them against predefined wiki rules. To perform this operation I am using astq nodejs module as it allows to use XPATH API on the AST tree.
3. To validate Parent-child JSX elements I am looping through the AST tree dynamically and recursively applying step2 for all the children associated with a parent using the javascript map interface. For this functionality I created a POC (proof of concept) which illustrates the behaviour and has been integrated into the main parser.

Thank you for watching my demo and I look forward to working with you!

Hi! I am Adeyinka and I am a Learning Dollars software engineer. I specialize in Javascript, Nodejs, React and Python. I have done projects in web applications and some bit of game development. Thinking and creating are hobbies to me so I enjoy singing, dancing, acting, cooking, playing chess, but to mention a few.

My first demo is an Uptime Monitoring App built purely with Nodejs (no dependencies) and vanilla Javascript ( very little HTML and CSS as the focus of this app is on the back end).

This application allows you to create an account as a user, have an active token as a signed up and logged in user and create a maximum list of 5 websites that you want to monitor.

Here is the home page, the sign up page and the login page. There are validations for the inputs on the signup and login with appropriate error or success messages. On successful login, you find yourself on your dashboard with a list of all checks you have created. You can create/add a new check and find it in the list of checks. You can also view/edit/delete a check.

You can edit your details in the account settings page however just the name and password are editable. You can also delete your account if you are longer interested in having an account. This would delete all checks you have if any and delete every detail related to you as well.

If you enter a valid phone number, you should get an sms when the status of any of the websites you are monitoring changes.

My second demo is a Document Management System built with Nodejs and React and Redux.

This application allows you to manage documents, users and user roles. On successful login, you get to see all documents you have access to (public and private) in a paginated format. You can create documents, edit your own documents, delete your own documents.

As an admin, you can see a list of all users in a paginated format as well and promote/demote other users. You can also perform a live search for users and also for documents.

Thank you for watching my demos and I look forward to working with you!
