PROFESSIONAL SUMMARY

Full Stack Developer with 14+ years of experience building and shipping web applications on .NET Core, Angular and Microsoft Azure.

AI-ASSISTED DEVELOPMENT EXPERIENCE
  • GitHub Copilot: daily use in Visual Studio and VS Code (completions and Copilot Chat) for C# and Angular/TypeScript: boilerplate, EF Core queries, DTOs and mappings, component scaffolding and unit test drafts.
  • ChatGPT & Claude: design discussions, stack-trace debugging, refactoring legacy code, SQL query optimization, code explanation, technical documentation and API contract drafting.
  • Prompt engineering: write context-rich, specific prompts and iterate on results to get production-quality output instead of generic snippets.
  • Responsible use: AI output is treated as a draft. Every change is reviewed, tested and checked for security and performance, and no client secrets or sensitive data go into prompts.
