Experience

Solution Union Refactoring of the existing white label multi tier portal

https://appmarketdirect.azurewebsites.net

I redesigned and refactored the existing online payment and customer management portal. The project included payment logic changes, multi-tier infrastructure design, and full front-end redesign. The application moved from an on-premise server to Azure Cloud.

SolutionUnion Portal

https://securesitecontrol.com

This is a white-label web portal that allows a customer to sign-up and buy products. The products are cloud-based applications that are integrated into the portal via an API. The portal calculates the customer's monthly usage based on their daily usage and provides reports to customers, invoices, and bills.

CPCAB Web Application with Full Content Management

http://www.cpcab.co.uk/

This is a .NET C# and MVC Razor web application with rich admin functionality. It enables the full management of content, CRUD sections, customization to the HTML part in each section, and control over the sections without needing a developer.

Cloud Service Provider

https://solutionunion.com

This project revolved around a company representation/promotion website that promotes current products and prices and compares them to other competitors.

I worked on both the UI and back end of this website. I also performed SEO optimization and hosted it on the IIS server.

Music Lesson Booking Platform

https://classicnobles.com

This web app allows a user to book music lessons during available slots. The administrator can manage bookings, contents, files, and news. It has a feature that enables the user to block certain time ranges or set the blocked range to repeat.

I developed both back end and front end and hosted in the IIS server.

Line Follower Robot

This project involved a line follower robot that can be controlled via a smartphone. The robot should be able to self detect the lines and move accordingly. It should also perform special signals which are drawn near the lines.

I developed the Java Me application for smartphones for image processing, the Bluetooth signal sender/receiver, and microcontroller for hardware commands.
