- Experience with backend infrastructure and cloud infrastructure (AWS/GCP/Azure)
- Proven ability to design systems that scale horizontally across multiple servers/instances
- Track record of improving cost efficiency without breaking SLOs (latency/uptime)

- Postgres/MySQL at scale; Redis; Kafka/RabbitMQ/SQS; CDN and edge caching
- Security best practices: WAF, rate-limits, secure secrets management, hardening
