I completed this project for a chemical manufacturing company about two years ago. The company used a program written in FoxPro back in the '90s to manage their inventory. Since they had grown to multiple locations, it was becoming difficult to manage using a stand-alone application.

I led a team of two to develop a web application that would enable them to manage their inventory and day-to-day transactions from multiple locations. I was responsible for designing the application and implementing its back end, which involved creating a web server, APIs, databases, and writing the core logic of the application.

We included some additional features in the redesign that would enable them to gain insights into their data. For example, based on the historical data of production and sale of a particular product, we would recommend how much of that product they should produce in the next batch and how much raw material they would need for its production. This feature was incredibly beneficial as they wouldn't have to calculate this manually for each product each time.

I completed this project for a start-up that wanted to create a cycle servicing app. I worked with a small team of four, including one UI/UX, one Android, one iOS, and one back-end developer. I oversaw the back end development and assisted with the Android app.

For the back end, we decided to go with a serverless architecture to remove the burden of server management and allow for automatic scaling. We went with Google's Firebase as it provided the most cost-effective plan.

I set up phone number- and email based-authentication, creating NoSQL databases in Firestore, creating a storage bucket in Cloud Storage for storing images and other resources, writing functions in TypeScript using Cloud Functions, setting up Crashlytics to report app crashes, and setting up Cloud Messaging for sending push notifications.

Unfortunately, the app didn't go past beta due to a lack of funding.

This project started as a way to find how I could control non-IoT devices such as lights and fans as IoT-enabled devices. Items such as smart bulbs are quite expensive, and it didn't make sense to buy 20 of them for the entire house. So I decided to put my engineering degree to the test.

I built an AVS device SDK (Alexa) on Raspberry Pi in conjunction with IFTTT and Webhooks, which allowed me to control non-IoT devices. Later, I added an LCD screen to the Raspberry Pi to create digital switches to control the lights in case the internet went down. To do this, I created a local server using Flask.

Next, I wanted to control these switches from anywhere in the world and not just from inside the house, so I created an app that would communicate with the HAS using a messaging service.

I created a HAS built using Python on a Raspberry Pi, enabling me to control my home switches through voice, touch, and an app.
