What I'm looking for

I seek roles where I can lead and build scalable data platforms, deliver analytics solutions, and collaborate across engineering and business teams in a results-driven, pragmatic environment.

I am a senior data engineer and analytics consultant with broad experience delivering enterprise analytics, data pipeline, and integration solutions for major clients across telecommunications, finance, and public institutions. I lead small consultant teams, capture business requirements, design robust solutions, and manage implementation and delivery.

My projects include designing centralized logging with the ELK stack, building real-time streaming and batch data pipelines using Kafka, Spark, Hive, and HBase, and implementing Hadoop and Cloudera environments, Kubernetes-based containers, and DevOps tooling such as GitLab and Jenkins. I have also developed automation and testing solutions using Python and Selenium, and built data science enablement platforms like JupyterHub with Papermill.

I hold a Master of Information Technology and a Bachelor of Computer Science, and I am an Oracle SOA Suite 12c Certified Implementation Specialist. I focus on delivering reliable, scalable data infrastructures and actionable analytics that align with business goals and operational needs.
