Abdirahman Abdullahi Jamaa
Senior Full-Stack Engineer · AI Systems Architect · Cloud Infrastructure
Abdirahman is a Senior Full-Stack Software Engineer with 6+ years of experience designing, building, and shipping production-grade software systems. He is the architect and sole engineer behind the entire FaidaAI platform — from the AI inference pipeline and WhatsApp integration layer, to the multi-tenant backend infrastructure, real-time dashboard, and payment systems.
With a Bachelor of Science in Information Technology and multiple professional certifications spanning full-stack development, AI/ML, cloud infrastructure, and cybersecurity, Abdirahman brings enterprise-level engineering discipline to everything he builds.
He specialises in AI-powered product engineering — taking large language models out of demos and into production systems that handle real users, real data, and real business logic at scale. FaidaAI processes millions of WhatsApp messages across East Africa and runs with 99.9% uptime on infrastructure he designed and maintains himself.
Abdirahman founded Sahan Labs with a clear mission: build world-class technology for African businesses that is affordable, reliable, and deeply adapted to how commerce actually works on the continent.

The Story Behind FaidaAI
FaidaAI was born out of a simple observation: WhatsApp is already the backbone of commerce across East Africa — from small kiosks in Gikomba to fashion boutiques in Westlands — but business owners were drowning in messages. Hundreds of customers asking the same questions about prices, stock, and delivery, every day, at all hours.
Abdirahman designed and built FaidaAI to solve that. An AI assistant that lives inside WhatsApp, handles every customer inquiry instantly and professionally, manages orders, and only alerts you when a human touch is genuinely needed. Your customers get faster, better service. You get your time back.
Today, FaidaAI serves businesses across Kenya, Tanzania, Uganda, Ethiopia, Somalia, and beyond — from solo entrepreneurs to enterprise brands. Every single feature was designed, coded, tested, and shipped by one engineer.
What We Stand For
Africa First
We design for African market realities — M-Pesa payments, multilingual customers, WhatsApp-first commerce. Not as an afterthought, but as the foundation.
Customer Obsession
Every feature starts with a real problem from a real business owner. We answer every support message personally and iterate based on real feedback.
Trust & Transparency
We handle conversations between businesses and their customers — a serious responsibility. We are transparent about data use and we never sell it.
Ship Fast, Improve Always
We iterate quickly based on real feedback. Ship something useful today, improve it tomorrow — rather than perfecting things in isolation.
