Hi there, I'm Isaiah Clifford Opoku 👋

I am a Software Engineer, Microsoft MVP, and Open Source Developer. I build production-ready libraries, developer tools, and APIs things engineers actually reach for to get work done. When I'm not writing code, I'm writing articles, recording tutorials, and sharing everything I learn with the community.

📧 Want to connect with me? Reach out via email: opokuisaiahclifford123@gmail.com

Microsoft Most Valuable Professional (MVP)


Open Source Projects

Open source is where I do some of my best work. Here are projects I've shipped that are live, used, and available for the community:

  •  Clifftech123/AzureStorage.Standard: A simplified library wrapping all four Azure Storage services (Blobs, Tables, Queues, Files) with built-in Polly retry policies and consistent error handling.
  •  Clifftech123/unio: One API, every format. Extract strongly-typed data from Excel, CSV, PDF, JSON, and XML. Auto-detects the format, streams large files via IAsyncEnumerable<T>, and ships a DI-ready interface. Zero external dependencies in the core package.
  •  Clifftech123/CountryData.Globalization: A high-performance library with 250+ countries, regions, currencies, phone codes, and full culture/region integration. O(1) lookups, thread-safe, zero dependencies.
  •  Clifftech123/CountryData.js: A comprehensive offline Node.js package for global country data (names, phone codes, regions, flags, currency symbols). Supports both JavaScript and TypeScript. 14 stars, 7 forks.

Technical Writing & Content

I write and teach .NET, Azure, and software engineering across multiple platforms. Come check it out:

  •  YouTube — @CliffTech: video tutorials on .NET, Azure, and building real-world software
  •  freeCodeCamp: in-depth .NET and cloud tutorials read by thousands of developers
  •  Dev.to: practical guides and engineering how-tos
  •  clifftech.dev: longer-form posts, project breakdowns, and deep-dives
