• In-depth, practical knowledge of Prisma or Drizzle ORM, with experience in building complex queries and managing migrations.
• A profound understanding of caching strategies (e.g., in-memory, distributed cache, CDN) and the ability to apply them effectively to optimize performance (e.g., using Redis).
• Full proficiency with Docker for creating, managing, and deploying containerized applications. Experience with Docker Compose is essential.
• Understanding and practical application of background workers and message queues (e.g., BullMQ, RabbitMQ) for handling asynchronous tasks.
• Proven experience in building secure systems, including protecting against common vulnerabilities (OWASP Top 10), configuring Content Security Policy (CSP), CORS, securing APIs, and hardening hosting environments.
