I built ReviewIQ because technical interviews don't always test whether you can actually review code.
ReviewIQ is an AI-powered code review interview trainer built for software engineers.
You pick a role, language, and seniority, then get a realistic PR diff with bugs intentionally planted in it.
You write your review.
Then the system grades it against the actual bugs, shows what you caught, what you missed, and gives you feedback on how a stronger reviewer would approach it.
The interesting part was building the grading system so it isn't just "AI thinks your answer is good." The bugs have a known ground truth, so the review can be evaluated against something concrete.
Built with Next.js, Supabase, PostgreSQL, OpenAI, and Lemon Squeezy.
I'm interested in building more products where AI isn't just a chat box, but an actual part of the product experience.
The known-ground-truth approach is a great product decision—it makes the feedback feel earned rather than like an opaque AI verdict. I also like that the flow tests the actual review skill instead of rewarding pattern-matching in interviews.
Exactly. That was one of the main things I wanted to solve. A lot of AI interview tools end up feeling like “the model says you did well,” which isn't very useful. Having the planted bugs as ground truth makes the feedback much more concrete. I’m curious whether you think the...

🚀 Recently launched a Webflow build for Toronto-based intellectual property (IP) software startup. The team at Clerq and Overline were brilliant to work with, and had incredible vision to make this one stand out.
Clerq, rebranded from NL Patent, is an agentic AI platform that automates patent workflows. Overline led the rebrand and designed the site, then handed it over to me to build in Webflow.
Really grateful to be chosen to work on this one, and deliver a solid site for Clerq to move forward with.

SaaS interfaces need clarity.
But clarity doesn't have to mean sterile.
With CORESPACE, the gooey effect is a small moment where the visual system gets to be more expressive.
It doesn't explain the product.
It doesn't add functionality.
It simply gives the experience some character.
Sometimes that's enough to make a product feel memorable.
The win here is placement. A gooey moment on the hero adds character, the same effect on a data table or form would just tax the task. Putting it where the eye is already resting is what makes it read as personality instead of noise.
Apparently I'm top 5% on Contra now.
Ten years of making SaaS explainer videos and the animation is still the fastest part of the job. What eats the time is sitting with the product until I can say what it does in one sentence. A lot of the videos I get asked to fix skipped that bit, and you can tell.
Anyway. Nice to see the number go up. I've got space for a couple of projects this autumn if you're launching something.
Congratulations!!
