Fraud Detection Distributed Systems Machine Learning

"Professionals use their skills for good and write code others can understand."

About Me

Senior Software Engineer with over six years of experience architecting high-scale monitoring platforms and real-time distributed systems that meet global demands. I have moved from implementing Java-based backends to architecting monitoring platforms and navigating high-stakes technical strategy across Europe and the Asia-Pacific.

Much of this work has been rooted in the fintech sector, where I have collaborated with multidisciplinary teams from diverse technical and cultural backgrounds. I am particularly drawn to complex challenges that test my technical limits, drive me to new perspectives, and equip me with the advanced skills necessary to excel.

My technical foundation includes object-oriented design and distributed systems with hands-on experience in Cassandra, Spark, RabbitMQ, Zookeeper, Docker, Prometheus, Grafana, Graylog, Jaeger, and AWS services such as EC2, S3, and CloudWatch.
