Summary

Software engineer with 7+ years building cloud systems and backend platforms — currently Development Expert at SCCC, helping run Alibaba Cloud in Saudi Arabia. I modernize databases and backend platforms (PostgreSQL, MySQL), build billing-grade systems in Python and Java, and work across Kubernetes, Keycloak identity, and agentic AI tooling. I enjoy sharing knowledge and shipping systems that keep working after the demo is over.

Experience

Saudi Cloud Computing Company — SCCC (Alibaba Cloud KSA)

APR 2023 — PRESENT · RIYADH

Development Expert

  • Lead modernization of production backend platforms, including MySQL → PostgreSQL migrations with production-safe strategies: concurrent indexing, lock-aware changes, and careful cutovers.
  • Operate and tune highly available PostgreSQL — Patroni-based clusters, replication and failover, autovacuum and bloat management, slow-query analysis, and memory/performance tuning.
  • Design and build a revenue-management platform (FastAPI + PostgreSQL): consumption processing at millions of rows, VAT-precise calculations, customer billing cycles, allocation priority rules, and automated data-quality checks; evaluated billing engines (Lago, Kill Bill) against complex invoicing requirements.
  • Implement identity and SSO with Keycloak across SAML and OpenID Connect — JWT validation vs introspection, Alibaba Cloud RAM integration, and migrating Spring Boot / Spring Security services to Keycloak.
  • Run containerized workloads on Kubernetes with Helm and ArgoCD; CI/CD through Jenkins and GitLab CI; observability with Prometheus and self-hosted Sentry.
  • Develop agentic AI tooling — LLM-powered agents that automate engineering and operational workflows end to end.
