Hello, I'm Osama

👋

I'm a product-centric software engineer specializing in building robust and scalable web applications. I love working with complex problems and converting them into simpler solutions. Welcome to my portfolio!

About Me

I have more than 2 years of experience as software engineer, specializing in full-stack development. My journey in software development began with a bachelor's degree in Computer Science, which laid a solid foundation in programming and problem-solving skills.

Throughout my career, I have worked with various technologies and programming languages, including Javascript, Python, Java and Kotlin. I have strong background in developing web applications, and particularly passionate about creating user-friendly, efficient, and scalable solutions. I have experienced working with microservices and event-driven approach. My most recent role is with Rewaa, where I am part of team which builds omni-channel system. The project not only honed my technical skills but also improve my abilities in teamwork and communication.

I am always eager to learn and grow. Apart from my work, I regularly engage in professional development activities. This includes taking online courses to stay updated with the latest technological trends.

In my free time, I enjoy attending tech meetups and seminars. I love playing and watching football and read a lot about financial markets.
