Hi, I am Yitzkak Agu — a computer scientist, AI practitioner, and the person behind every article on this site.
I studied Computer Science at the University of Nigeria, Nsukka. After that, I went deeper into machine learning through Andrew Ng’s Neural Networks and Deep Learning course on Coursera, and completed LangChain: Chat With Your Data on DeepLearning.AI. Those two courses changed how I think about what is actually happening inside these models and what it takes to build something useful on top of them.
I also work as a QC editor at Scribie, where I have reviewed thousands of hours of transcribed audio for accuracy, formatting, and consistency. That job gave me an unusual angle on AI: I was evaluating language quality professionally right when LLMs started disrupting what that even meant. Watching that shift from the inside pushed me to start building, not just reading.
What I Have Built
- Fine-tuned LLMs on custom datasets
- Built a multi-agent research pipeline connecting Perplexity, Claude, and n8n
- Deployed a website monitoring agent using DeepSeek as the classifier brain
- Built this WordPress site from scratch using AI tools for under $10
- Use OpenClaw, a skills-based local agent framework, to run most of my automation workflows
- Founder of Scriptorfi.com, a human-verified transcription platform
Why This Site Exists
Most AI content is written by people summarizing other people’s work. I wanted a place where the content comes from actually doing the thing: running the code, paying the API bills, hitting the errors, and documenting what happened. Every build walkthrough on this site reflects a real project. The costs are real. The failures are included.
I also publish selected long-form pieces on Medium, where ainskills.com is always linked as the canonical source.

A Note on AI in My Writing
I use AI tools as part of my research and drafting process. Every article reflects my own experience, testing, and judgment. I do not publish AI output without reading, verifying, and rewriting it. The builds I document are real.
