Strong Plus

• Experience building developer platforms or public SDKs
• Familiarity with AI/LLM ecosystems (LangChain, agents, tool calling)
• Experience with plugin architectures or extensibility frameworks
• Background in data platforms, databases, or infrastructure tooling
• Experience with async systems, concurrency, and high-throughput services
