What I'm looking for

I seek backend roles focused on distributed systems or fintech, where I can design reliable, scalable payment or event-driven platforms and grow into architecture leadership.

I am a backend engineer focused on building resilient, event-driven financial systems and scalable backend services. I design robust architectures that prioritize data consistency, reliability, and operational efficiency.

At Rvin.sa I architected an event-driven wallet and payment system using Apache Kafka, designed 10+ financial database tables, and implemented a double-entry ledger with full ACID guarantees to ensure 100% debit/credit consistency.

I applied Outbox + Inbox patterns and built a crash-resilient ledger engine using Celery and Redis with exponential backoff, late acknowledgements, and DB-level locking to minimize duplicate events and enable automatic crash recovery.

I also delivered an HLS streaming pipeline that offloaded media delivery to Nginx, integrated AI-driven backend automation for content processing, and during an internship improved engagement metrics and reduced infrastructure costs through backend optimizations.
