az-bitcoin-network-website

A website I coded from scratch for a local group of ~150 bitcoiners. https://azbitco.in/

banking-app

This project utilizes inheritance, polymorphism, and encapsulation to demonstrate my understandings of the basics of object oriented programming.

btc-lightning-faucet

Written in React, this faucet allows users to "pull" sats directly into their lightning wallet with a single tap. The cool thing about this is that the user isn't required to scan a QR code or copy + paste a LN invoice.

btc-restaurant-point-of-sale

This is a point of sale GUI app written in Java. Upon finalizing a bill, a request is made to OpenNode's API and presents the user with a real bitcoin Lightning Network invoice as well as an on chain address. This functionality is built with Maven.

collections-project

This project demonstrates my knowledge of Java Collections. This program iterates through every English word (~64,000 words) and uses Queues, Stacks, LinkedLists, etc. The program scores each word according to the tile scores in the board game Scrabble. Anytime a higher scoring word is found, it is added to a Stack and printed out at the end.

react-full-stack-blog-app

This React web application has a front end that communicates to a backend using Sanity. The purpose of this app is so that the blogger (a person I know in real life) can login into the backend, type some text, drag and drop some photos, tweak a few settings, etc, and manage their blogging website in real time without the need to touch any code. This app is hosted with Netlify so that as soon as the blogger publishes something, the website updates in real time automatically.

react-full-stack-ecommerce-web-app

This React app demonstrates proper component architecture as well as state management with Redux using the following data flow: Action/Event -> Dispatch -> Reducer -> Store -> State -> View. I enjoyed using Redux because it avoids "prop drilling" and while it takes some configuration time, I can see how it allows applications to be built in a much more scalable manner. I also learned how to implement Google's Firebase as a backend for user auth and database management. Bitcoin payments were added using OpenNode's api (supports both on-chain and lightning payments) which I am very familiar with. Stripe payments are implemented via Stripe api but commented out.

react-native-bitcoin-messaging-app

A React Native app I built that fetches data from bitcoin blockchain apis and displays it. Key skills I Iearned in this project were using real API's, hooks (useEffect & useState), and npm packages such as RefreshControl and useTheme. This app also includes advanced React Navigation features as well as built in messaging using ChatKitty.

react-native-currency-converter

A React Native currency convertor app I made following a tutorial on https://www.reactnativeschool.com/. This app fetches data from a mock api (static and offline). The main takeaways I had were imports/exports, state management, intro to API's, functional components, and react native navigation.

react-rolodex-app

This is a single page web application written in React. This project helped me learn the basics of "top down" data flow in React and how to manage state. This was also a good refresher on basic react components, context, and class based components vs functional components.
