• Agentic / orchestrated approach to the solution, including AI/LLM agents, managed workflow, and iterative processing.

  • AI/LLM layer for iterative SQL tuning and edge-case resolution.

  • Automated data validation with feedback loop (error → AI → re-run → validation).

• Collaborate on the selection of appropriate tools and technologies, including experimental evaluation.

• Define framework operating modes: batch and on-demand, including variants usable by business users

• Implement the framework with workflow orchestration.

• Integrate key components: SQL translation tools, data validation tools, and Git-based workflow for change detection, branching, and auditability.

• Design and implement batch and on-demand launch modes.

• Optimize the deterministic translation component before applying AI to increase translation accuracy.

• Collaborate with BI and NDP architectural teams to align the framework with the target platform architecture.
