• Practical experience integrating or working with large language model (LLM) APIs or generative AI tools (Claude, GPT, Gemini, or equivalent) in production backend systems.
• Strong SQL skills including schema design, query optimization, and stored procedure development across one or more relational databases.
• Proficiency with RESTful API design, JSON data modeling, and microservices communication patterns.
