Joe Reis Portfolio
Site of Joe Reis, co-author of the bestselling O'Reilly book Fundamentals of Data Engineering and co-creator of a Coursera data engineering specialization with Andrew Ng, combining a Substack newsletter, a podcast, and an in-progress book on data modeling.
What makes it work
A breakdown of the choices that make this portfolio stand out.
A book's reach extended through ongoing companion content
Rather than letting the book's launch be the end of the story, a "2.5 years later" retrospective essay and a follow-up book on data modeling keep building on the original work's audience over time.
Multiple content formats reinforcing the same expertise
The same core expertise (data architecture and modeling) shows up as a book, a Coursera course, a newsletter, and a podcast — each format reaching a different kind of reader without diluting the underlying material.
Clear boundaries on what he does and doesn't take on
Explicitly stating he accepts speaking and advisory work but not general consulting sets an honest, specific expectation for site visitors instead of a vague "let's talk" catch-all.
What Data Engineers can take from this
Specific, actionable tips to apply to your own portfolio — no generic advice.
If you've published a book or major project, write a retrospective on it a year or two later — it shows the work still holds up and keeps it discoverable.
Repurpose one body of expertise across a few formats (write-up, course, talk) rather than treating each as a one-off — it reinforces the same authority everywhere a reader might find you.
State plainly what kind of work you do and don't take on; a specific, honest scope is more useful to visitors than an open-ended "get in touch."
