I acted as a full-stack developer with the following tasks:

• Architected the middleware using .NET Core, LINQ, and the Entity Framework.
• Designed and developed the cores of an Angular-powered front-end app from scratch using Bootstrap on the front end.

RFID Food-tracking System
It's a food box tracking system for a fancy chain restaurant in Malaysia that tracks all the information—starting when the food is prepared in the central kitchen and dispatched to a certain restaurant branch to when RFID devices detect that box has arrived.
I wrote all of the relative apps for this system.
Specific Tasks Accomplished:
• Configured the RFID devices.
• Developed Web APIs for handheld Android devices.
• Implemented the database schema.
• Created the Windows service for the main RFID device installed in the restaurant.
• Built the MVC web app for the main office's network that manages all the operations and shows all the stats on the web portal.
An admin could track all the boxes at any given time and the smart system also had the capability to mark boxes as missing if they didn't arrive at the restaurant within a specified time range.

News Production System
I redesigned the architecture of the news productions system for a top news channel. I created a server-client WinForms application with C# and Telerik UI controls with an event-driven pattern that communicated with three different servers of media, text news, and prompter.
This app was used by over 100 news writers 24/7. It used SignalR to communicate with other instances. I also identified and fixed the bugs in this application and other supporting Windows services and RESTful APIs, apart from writing new modules.

Stock Estimation App
I led a team of four other people in migrating this ASP.NET/WCF-based application into a blazing-fast SPA.
We used Angular on the front end, RESTful APIs in the middleware, an SQL database at the back end, and Ngrx for state management. We made this web app for one of our financial clients and with this, they can view the next three years pf predictions of any publicly listed company's stocks.
I also integrated ChartIQ for better data visualizations and developed an Excel web add-in so that our financial analysts could easily import their Excel sheets into our database. I also wrote the SQL procedures to be used in the APIs.

PropertyShares
It's an investment web app portal made for users looking to invest in construction and real estate in Australia.
Investors can check the real-time construction progress of their investments.
I added two more modules: Asset Manager and Borrower. I used ASP.NET MVC for the front end, implemented an Entity framework database-first approach as the ORM, and also wrote stored procedures from time to time for complex queries. For generating different reports, we used Syncfusion libraries.
I designed the UI/UX in Bootstrap from mockups and also fixed bugs in the existing features' code.
