KenyaWhat I'm looking for
I've delivered automation and data solutions for a Nairobi water billing system, accelerating billing processing by 81% through automated consumption ledgers, n8n workflows, and Google Apps Script.
At Safaricom PLC, I supported Python API integrations that reduced manual documentation effort by 62%, helped establish observability across 50 enterprise pipelines with Marquez and OpenLineage, and contributed to Kubernetes deployments and schema monitoring.
I've also maintained 15 production web platforms at Becor Designs, improved support resolution time by 44% through database optimization, and built projects spanning MLOps fraud detection, data lineage, AI scam detection, and automated billing.
