Key Topics

Efficiency Gains Through AI-Powered Modernization:
- AI tools accelerate screen translation and migration
- Reduction of manual processes, enabling faster turnaround
Two-Step Modernization Process:
- Step 1: System analysis and technical specification generation
- Step 2: Automated code, test creation, and client reviews with AI assistance
System Architecture:
- Use of FastAPIs for scalable and modern integrations
- Azure cloud infrastructure hosts new solutions and supports seamless operations
Finalization Procedures:
- Output file creation and technical documentation
- Pseudocode generation supports validation and quality controls
AI-Driven Input Conversion:
- Specifications produced via AI serve as direct input for further development stages

Impact and Results

Migration achieved 3x faster than legacy approaches
Significant improvement in operational efficiency and modernization effectiveness
Cloud-based architecture enables ongoing scalability and integration of additional services
