What I'm looking for

I am looking for a role that fosters innovation and collaboration, with opportunities for growth and impactful projects.

I am a dedicated software engineer with a strong focus on backend development, particularly in Java. My experience spans across various projects where I have successfully contributed to the development of core microservices, optimized API performance, and implemented robust CI/CD pipelines. At OLX, I played a pivotal role in reducing deployment rollbacks by 30% and enhancing the performance of checkout and search APIs for over 10 million monthly users.

My journey in software engineering began with a Master's degree in Computer Science from the University of North Texas, where I honed my skills in various programming languages and frameworks. I have a proven track record of improving system efficiencies, such as reducing latency by 300ms in payment gateways and increasing code coverage to 85% through comprehensive testing. I thrive in collaborative environments, having worked closely with cross-functional teams to deliver impactful features and maintain high standards of code quality.
