About Anas

As a software engineer with expertise in cloud technologies, Kafka, Kubernetes, and DevOps, I have a strong track record of delivering reliable and secure software solutions, particularly for the banking industry.

My experience includes participating in several projects related to counterparty risk, fraud detection, and AML/CFT compliance, as well as real-time data processing projects, where I designed and implemented distributed systems deployed in the cloud using Kubernetes. I am proficient in Java and Python and their ecosystems, and I am skilled in the software lifecycle (development, testing, and deployment).

I am always looking for opportunities to learn and grow in my field, and I am currently seeking new freelance challenges and opportunities.
