In a subsequent update to the previous supplement sales company's application, I undertook several enhancements and modifications. The app was migrated from a Linode.com instance to an AWS EC2 instance, providing a more scalable and reliable infrastructure. I updated Vuetify and rebuilt the entire user interface from ground-up, resulting in a modern, improved interface. This process also involved fixing bugs and making necessary alterations to the MongoDB database.A significant feature added was a dual dark and light mode, offering users a visually appealing and customizable experience. A profile module was also integrated, allowing users to modify their email and password. Within the profile view, users could see their assigned role, which determined their permissions within the app. This experience furthered my experience in full-stack development, specifically in migrating applications, updating UI, and implementing new features.

In this experience, I collaborated on a telemetry system project, which consisted of three components: an ESP board with sensors and wifi connection, a MQTT broker with a NodeJS API on AWS, and a simple iOS App developed using React Native.On an AWS instance, I set up a MQTT broker using Mosquitto, which had the ESP board as the publisher and the NodeJS API as the subscriber. The ESP board, wired to several sensors, monitored the temperature, humidity, pressure, and light conditions of the office.Upon receiving the sensor data via MQTT, the NodeJS API distributed it to the apps using web-sockets. Each app maintained a persistent connection with the API on AWS, allowing it to continuously listen to the incoming data.Initially, I planned to set each instance of the iOS app as a subscriber to the MQTT channel, but due to constraints while developing the app using React Native, I opted for an API that subscribes to the MQTT channel and distributes the data to the apps via web-sockets.The choice of React Native for the app development was due to its simplicity and my existing proficiency with JavaScript, which expedited the development process. This project enhanced my skills in IoT, real-time data distribution, and mobile app development.

In this autonomous project, I developed two distinct web applications: an e-commerce application and an administrative application, both connected to the same MySQL database.The e-commerce application was a basic web application built with Laravel, VueJS, and Vuetify. Laravel Socialite was integrated for Facebook and Google sign-in functionalities. The homepage featured a full-width carousel, a color-customizable plant's pot component, a product carousel, a hot categories menu, and an aesthetically pleasing footer.The administrative application was a separate Single Page Application developed with Vue-CLI, Vuex, Vuetify components, and a Node.js backend for database interaction. It featured an upgraded version of Vuetify for improved component aesthetics, a dark mode option, and an authentication module. Depending on the assigned roles, an admin had access to different modules of the app.One of the most noteworthy aspects of this project was the storage of all media, such as images and logos, in AWS S3 rather than in a folder within the app. This required the use of the S3 SDK for storing, deleting, and moving images in S3. I also created a library to simplify the usage of the S3 SDK.The two primary challenges in this project were integrating AWS S3 and ensuring smooth user experience with HTTP requests. This project enhanced my full-stack development skills and provided valuable experience in handling complex functionalities.

For a supplement sales company, I developed a private system to manage the pricing of their extensive product range across multiple stores. The system was built using Vue-CLI, NodeJS, Express.js, MongoDB, Vuetify, Workbox, among other technologies. It was designed as a progressive web application (PWA), providing a Single Page Application (SPA) experience in a web browser, but additionally installable on mobile devices and PCs, ensuring accessibility and convenience for the users.This project allowed me to apply my skills in full-stack development and PWAs, contributing to a real-world business solution for product management.

I developed a fitness-focused forum as part of a personal project. The forum was built using Laravel, MySQL, Laravel Blade with integrated VueJS components, Bootstrap 4, among other technologies.The forum allowed users to register, log in, and customize their profiles. Users could post fitness-related articles and engage in discussions through comments. The platform also facilitated posting queries, which could be answered by other users, fostering a vibrant fitness community. An admin area was included to allow forum administrators to manage all data and monitor forum statistics effectively. While the project has since been taken down, the experience of building a fully functional online community from ground-up was invaluable. It allowed me to apply and enhance my full-stack development skills in a real-world context.
