Otieno Shikuku

I build, deploy and keep software running. I work across the stack, from backend services and APIs to the servers and clusters they run on, and I’m comfortable owning a project from first design to production.
Backend: Node.js and Go services, REST APIs, PostgreSQL, Kafka messaging, push notifications (FCM), and multi-service architectures.
DevOps and infrastructure: Linux server administration, Docker, k3s/Kubernetes clusters, Nginx, PM2, VPN/WireGuard networking, monitoring and production troubleshooting.
Frontend: React and microfrontend customization.
Integrations and automation: payments (M-Pesa), ERP systems such as ERPNext, bots (Telegram/WhatsApp), and LLM-powered tools.
Industry experience includes healthcare systems, among others.
How I work: clear milestones, a deposit before I start, regular updates and written handover docs. M-Pesa, bank or Wise accepted. Tell me what you need built or fixed and I’ll send a plan and quote within 24 hours.
