Cloud and data engineer specializing in AWS, data pipelines, and scalable analytics solutions.
KenyaWhat I'm looking for
I am a cloud and data engineer with over eight years of hands-on experience designing, deploying and supporting large-scale systems across mobile money, enterprise systems and data analytics.
My recent work at AWS focused on analytics and container services where I supported customers on QuickSight, Redshift, EKS/ECS, ECR and MSK, assisted migrations to AWS, and collaborated on service improvements and security reviews.
At Safaricom I built and optimized data platforms—deploying Apache NiFi, Druid, Spark, Kafka and Airflow—migrating ETL from Informatica to PySpark and delivering performance gains such as 40% faster file processing and significant MTTD/MTTR reductions via ELK log analytics.
I hold multiple AWS and cloud-native certifications and seek roles where I can apply cloud-native architectures, data engineering and operational excellence to solve high-scale analytics and fintech challenges.
