Frequently asked questions
Who writes these guides?
Muhammad Usman Akbar, founder of Hire Unicorn Developers and principal engineer at FISTA Solutions. The technical positions taken reflect his own engineering practice in AI agent systems, Forward Deployed Engineering and circular economy software.
How is the blog organised?
Into nine topical clusters, each with a pillar page and supporting articles that link back to it. That structure exists because topical depth, not article count, is what builds authority for both search engines and answer engines.
Are these articles AI-generated?
They are written and edited with a specific technical position in each piece rather than assembled from a template. Any article that cannot carry its own substance is marked as a draft and excluded from indexing until it does.
Can I follow new articles?
Yes, through the RSS feed at /feed.xml or the JSON Feed at /feed.json. Both include only published articles and carry the full author attribution.
