These are some of the technologies I am able to leverage in engineering apps that deliver value to their intended audience and become important business assets.
Below we explore the application of some of these technologies in a few case studies...
This component is comprised of two major concepts: logic and UI.
The logic covers the functionality of the calculator. Performing the operations, keeping track of app states, accounting for edge cases, handling errors, etc. This is all accomplished with JavaScript and it serves the purpose of applying key computer science concepts in programming.
For the UI part of the equation the goal was to replicate the look and feel of an iOS device calculator. Conditionally rendering CSS classes when the display digits reached 9 or 11 characters made for its UX functionality.
A 25 minutes timer that rings a bell when it reaches zero to announce the beginning of a 5 minute break. This clock allows the user to adjust the settings both for the Session and Break length. User is able to start, pause and reset the timer to its initial state.
So far the previous projects fall strictly in the realm of Front-end development, as they stay within the confines of React and the browser.
Now, let's explore a full stack application that brings Node.js into the picture for Back-end development...
This app serves as a lead adquisition and Customer Relationship Management (CRM).
It features use of the Google Maps API to pinpoint and validate service addresses.
On the backend it is powered by Express and MongoDB. It features an admin dashboard providing real-time count of online users and other events by leveraging Socket.IO and MongoDB's ChangeStream access to real-time data changes.
Detailed description of user stories are available in its GitHub repositories.
