KenyaWhat I'm looking for
I've built production data workflows at AmaraGrid-Africa using Python, FastAPI, Node.js, SQL, and Docker, owning backend architecture from design through deployment.
I designed Airflow ETL/ELT pipelines for real-time fraud detection, reducing fraud losses and pipeline runtime by 7%, and built Kafka and Spark streaming delivery to improve throughput and resource efficiency.
I have delivered CI/CD-backed data services, improved data availability by 60%, supported reliable processing for more than 3 million records, and resolved complex production issues at scale.
