Senior Software Engineer — AI Systems & Distributed Platforms
I build production-grade AI systems and distributed platforms for enterprise scale.
AI news intelligence platform for Africa — aggregates, summarizes, and analyzes news from 22+ Kenyan, East African, and top global tech/AI sources (Wired, TechRepublic, Google AI Blog, Hugging Face Blog, Hacker News, TechRadar). Features real-time clustering, entity tracking, and risk signal detection. Available on web and Android (Expo/React Native).
Impact:
- Aggregates news from 22+ sources in real time
- AI-powered story clustering, sentiment, and entity analytics
- Designed for researchers, tech enthusiasts, and anyone tracking news and AI trends
