I've delivered production platforms at Star Sphere, including transport and enterprise products serving more than 400,000 users. I own work end to end, from frontend and backend delivery through deployment and operations.

For riyada.iq, a national youth training platform with 400,000+ users and 500,000+ downloads, I built admin, supervisor, payment, and incubator dashboards and owned trainer approval and onboarding workflows. I also built the operations dashboard for karwatt.taxi, including drivers, passengers, approvals, support, Mapbox tracking, and real-time trip state.

I build with React, Next.js, Node.js, and REST APIs, while designing clean multi-tenant systems with strict data isolation. On nexorainventory.com, I developed a multi-tenant API with 50+ endpoints, query-layer RBAC, and an offline-first Kotlin scanner handling 1,300 tags per second.

I've grown from frontend delivery into cloud and infrastructure, containerising AWS deployments and operating Kubernetes through GitOps. My production platform uses ArgoCD, Helm, Prometheus, Grafana, Loki, automated TLS, and ingress to keep delivery observable and cost-conscious.
