Design the patterns required to integrate AI/LLM capabilities (e.g., agentic workflows, RAG pipelines) into the existing and future ecosystem.
Act as the final authority on architectural patterns, technology stacks, and coding standards to ensure consistency across the engineering team.
Proactively identify, quantify, and prioritize technical debt, balancing rapid feature delivery with long-term system health.
Provide high-level guidance to Senior and Mid-level developers, conducting deep-dive code reviews and fostering a culture of technical excellence.
