Engineering Experience

Architected and deployed highly secure, scalable backend infrastructure for an international government ministry. Engineered systems handling complex delegation workflows, scheduling, and strict regional financial compliance.

• ZATCA-Compliant Financial Engine: Engineered a centralized pricing and financial reconciliation engine processing complex transactions with 100% regulatory compliance.
• Async Export Pipeline: Built a high-performance Celery + Redis pipeline to handle 55+ complex data export types, completely eliminating API thread blocking and timeouts.
• Advanced Security Protocols: Implemented rigorous RBAC, OTP, sliding JWT sessions, CAPTCHA, and specialized brute-force/timing-attack protections.

Spearheaded the V2 API architecture for a high-traffic B2C learning platform scaling to 500,000+ downloads and 50,000+ daily active users.

• Database Optimization: Systematically eliminated N+1 query bottlenecks and redesigned core schemas, reducing average API latency significantly.
• Caching Architecture: Implemented comprehensive Redis caching layers to drastically reduce database load by over 60% during peak concurrent traffic.

Led the backend architectural design and AWS cloud infrastructure provisioning for enterprise initiatives.

• Cloud Deployment: Managed robust AWS deployments utilizing EC2, S3, RDS, and SES, orchestrated behind Nginx and Gunicorn.
• Engineering Leadership: Established standardized Git workflows, automated CI/CD pipelines via GitHub Actions, and mentored junior developers.
