About Me
Software Engineer specializing in AWS serverless architecture, CDK infrastructure-as-code, and building SaaS products that solve real problems. He designs multi-tenant platforms, cost-aware infrastructure, and WhatsApp-native applications for the Kenyan market. Currently building Awali — a WhatsApp-native RSVP and M-Pesa payments platform for Kenya — and Slate, a zero-config CLI that estimates AWS infrastructure costs before deployment by reading CDK output and calling the Price List API. He also created CertifyNow, a cloud certification practice platform covering 39 certifications across AWS, Azure, GCP, and Oracle, and InvoiceNow, a multi-tenant SaaS invoice management system with full CDK infrastructure. He holds AWS Cloud Practitioner certification and his expertise spans TypeScript, Vue, React, AWS CDK, Firebase, serverless architecture, and M-Pesa integration. He speaks on AWS cloud architecture, pre-deployment cost estimation, building SaaS products for African markets, WhatsApp-native applications, and multi-tenant architecture, focusing on practical frameworks that engineering teams can implement immediately. Paul builds for impact. Every project starts with a real problem — whether it's Kenyans chasing RSVPs in WhatsApp groups, engineers discovering surprise AWS bills after deployment, or certification candidates scattered across expensive platforms.
