Experience

Machinery and Equipment Metadata APIs

Worked on critical Metadata APIs developed in C# and the .NET Framework with a SQL database back-end and contributed to the development of new modules and features that enhanced API functionality. These APIs are consumed by over 200 clients and applications across Europe, Canada, and the US. To handle the high volume of requests efficiently, implemented several performance optimizations to improve endpoint response times. Additionally, integrated distributed caching (Redis) for specific data sets and migrated from in-memory caching to Redis to enhance data retrieval speed and scalability.

Snoonu

https://snoonu.com/
I developed an eCommerce website for the food industry, formed with a microservices architecture. Most microservices were developed in ASP.NET Core, some have NoSQL databases like MongoDB, and some have SQL databases like MSSQLCE and PostgreSQL. In some cases, microservices did third-party integrations like fetching orders from outer vendors like KFC. It has a mobile application for both iOS and Android. Working on this project was an immense learning opportunity.

Tax Dep

I designed a platform to calculate user taxes to be paid in recent and coming years. This product primarily handles tax calculations in the construction domain. A constructor can add its running projects to the application and, based on the project and property values, project the tax to be paid in the coming years as per the current tax policy. We designed and developed the MVP of this platform and obtained approval from multiple clients.

Marketplace

I developed a web platform that enables multiple hospitals and healthcare professionals to register and create and assign jobs. Work rates are calculated based on skills and other unique factors. HCP submits the timecard, and the admin approves it. It also includes the integration of various systems.

BASF Platform

I created a web platform to collect quotation requests from different suppliers against the listed items. Based on RFQs, users can run multiple English and Dutch auction rounds to get the best quotation from competitive suppliers. The system evaluates the best quotation after calculating all taxes and bonus items on the quoted price and converts it to the base currency. Using GCM, users can assign items to suppliers, and suppliers can view the awarded items and the total amount spent.

Equiphounds

https://equiphound.com/
Created an eCommerce site based on the NopCommerce eCommerce platform. I developed this platform in ASP.NET Core. We used the platform and made customizations in some sections according to the customer. Users can sign in to the application and buy machinery and equipment for different industries.

Food Chapter

An eCommerce website for ordering homemade foods. The website was developed using C#, Entity Framework, JavaScript, Ajax, HTML/CSS, and Bootstrap, and REST APIs are written to support multiple clients' mobile apps and web browsers. Users can order customized food choices and have them delivered to them.

School Care Pro

A web application that manages the maximum operations of the education institutions. It ranges from student registration, fee processing, attendance management, staff payrolls, staff timetable, and student result management. I was involved in this application from scratch. I built and designed different modules for this application and wrote APIs to support multiple clients, such as web browsers and mobile applications.
