Experience

Scania Financial System

I developed a highly efficient financial system for Scania, utilizing concurrent .NET microservices to accurately calculate costs during various truck production phases.

As a skilled back-end developer, I worked closely with key stakeholders to understand their business requirements and architected a solution with scalability at the forefront. I successfully built and deployed the necessary services while addressing and resolving any issues during development.

ENOC Gas Station's Online Services

As the main developer on the project, I was responsible for helping ENOC, a leading oil and gas company, build a middleware integration system that connects all gas stations in Dubai to various online services. I personally developed most of the online service integrations, allowing customers to easily pay bills, purchase flight tickets, and buy gift cards.

This system achieved exceptional success, generating hundreds of millions of dirhams every month. My experience as a lead developer and my ability to successfully integrate online services make me a strong candidate to help your company drive revenue growth through digital transformation.
