Experience

MangoCrisp

MangoCrisp is your AI culinary genie in a bottle. Create mind-blowing dishes with your imagination. Each recipe you generate consists of a list of ingredients, a set of instructions, and three unique images.

PyraMetrik

https://pyrametrik.com

It is a React-based (Next.js) web app to conduct lightning-fast stock analysis.

Over 4 billion unique angles to perform lightning-fast stock analysis. Each angle is called a 'composition.' A composition is a collection of specific metrics painting a particular picture of a stock.

I was tasked with performance optimizations, which included server-side rendering, client-side pre-rendering, HTTP caching, code-splitting, lazy-loading, image pre-loading, and stated-based caching that made load times and UX up to 100x faster.

Open-source Blockchain Ethereum Starter App

https://github.com/Nikhil22/angular-truffle-starter-dapp

An open source starter app built with Angular 4 and Truffle. The project is a boilerplate app that allows users to compile and deploy smart contracts on the Ethereum blockchain. The app is one of the most starred Angular-Truffle integrations.

Truffle Quick Start Guide

https://www.packtpub.com/product/truffle-quick-start-guide/9781789132540

This book covers the writing of smart contracts and the building of decentralized applications with Truffle.

It starts with the basics of Truffle, briefly explaining how it integrates Solidity and Web3. Then, it goes into migration, testing, and integrating Truffle with the use of popular JavaScript frameworks. Lastly, it covers shipping your decentralized application and packaging it into a product.

The goal is for the reader to be able to write smart contracts and build decentralized applications with Truffle on Ethereum blockchains.

CryptoTrend
