Sales Development Platform
https://salesocean.ioAccess to this project is upon request.
This was a full-stack project using mostly, but not limited to, front end technologies including React, Redux, Material-UI, Node.js, back end technologies Express, Mongoose, and MongoDB Database.
This project also involved heavy integrations with API from Google, Office 365, Hubspot, and Pipedrive. Moreover, it has an SMTP and IMAP level integration for mailbox synchronization. It is hosted in the Google Cloud Platform with a microservice architecture and many cron jobs.
The most challenging part of this project was its size; it had many different facets that needed to work together while being scalable and reliable at its core.
Native Desktop Application
The purpose of the application was to automate and standardize business processes and reporting across offices. The application supported employees in how they work, reported to clients, and analyzed their work.
The main technologies I used in this project are Electron.js, React, Node.js, JavaScript, and CSS.
Chrome Extension
The extension was built in JavaScript, HTML, and CSS. It is heavily relying on Chrome API and Chrome storage.
