- Legacy Modernization: Extract core business logic from monolithic legacy applications and safely transition them to modern microservices, overseeing the final decommissioning of old systems.
- AI Integration: Utilize top-tier LLMs (Gemini, Claude), Agentic AI, and RAG workflows to analyze legacy code, map dependencies, and generate optimized target code.
- Cloud & MLOps: Architect scalable, resilient environments on Google Cloud Platform (GCP) using Kubernetes, and establish comprehensive MLOps pipelines.
- Rapid Prototyping: Leverage "Vibe Coding" techniques, the Blitzy toolset for high-performance processing, and the Antigravity framework for data migration and state management.

- Required Frameworks: Technical mastery of the Antigravity library, Blitzy toolset, and "Vibe Coding" methodologies.
- Analytical Skills: Willingness to perform deep "archaeological" code reviews to understand undocumented legacy behaviors and optimize the computational cost of new models.
