Ito▲449I'm Evan and I made Ito.ai It's code review that actually runs your code. The result is that it finds more bugs with a smaller false positive rate. You get screenshots, videos, and run logs. I built Ito because manual verification sucks and I thought I could automate it. I've been a professional developer for 15 years and now more than ever, I'm just spending time making sure things work. I looked into all of the other agentic testing tools that click around a url you give them and frankly, they sucked. They just didn't work. I figured to be able to actually testing things you need to run…

I've long had a dislike for leetcode interviews on both sides of the coin. Project-based interviews can also be challenging because it can end up filtering out folks who don't want to spend several hours building something in their free time. I met up with a friend last year -- a very senior dev -- who had taken some time off to study leetcode exercises while preparing for FAANG interviews. It struck me that one of the key measures of whether a candidate is a fit for a team is rather synthetic. CodeRev.app is a simple, lightweight tool that helps teams evaluate candidates using code reviews.…

CodenQuest▲282Hello everyone, I've been working on a project called CodenQuest, a coding practice app inspired by platforms like LeetCode, but with a major twist: it's heavily gamified, similar to Duolingo. The main goal is to make coding practice more engaging, especially on mobile. Key Features: - Diverse coding questions with integrated hints and timers. - Code editor with code completion and fill in the blanks questions - Performance statistics (runtime, memory, CPU usage, and more). - Gamified elements: leagues, ranking systems, daily challenges, friends, and streak mechanisms. - Available on iOS and…

I created http://devtest.net as a weekend project, and I'm pretty proud of it from a technical and UI standpoint. The problem is, I've built this by myself in a bit of a vacuum, to "scratch my own itch", and I don't know if this is useful to anyone other than me. I'm also not so hot on the business side and don't really know what I'm doing. Basically, I'm looking for some advice, now that I've actually launched, what now? One thing that this has shown me is that I'm capable of putting together a pretty decent web application on my own in my spare time. Should I stick with this idea, or…
