- Utilized GitHub Copilot (chat, collaborating by assigning tasks, and reviewing PR descriptions) for a significant portion of the codebase, achieving an estimated 40-50% increase in development velocity on tasks compared to traditional methods.
- Collaborated with the client and team using natural language prompts to guide the AI, effectively acting as an "AI Orchestrator" and focusing on high-level architecture and user experience rather than manual coding.
- Managed the AI development lifecycle, including effective prompt engineering and validation of AI-generated code to maintain compliance with project standards.
- Implemented best practices into Blazor UI code for state management, component lifecycle, authentication, DDD, clean architecture, etc., and then documented the applied architectural patterns for the AI assistant.
- Rebuilt the legacy telecom ERP as a high-performance .NET 10 Blazor Server modular monolith, systematically decoupling business domains into 14 distinct bounded contexts.
- Implemented a robust front-end architecture combining clean architecture, domain-driven design (DDD), Fluxor (Redux-style state management), and a Facade/CQRS boundary styled with Tailwind CSS and Syncfusion.
