My Cobra AI - I freed an AI Agent and let him do what he wants

An autonomous AI agent running 24/7 on a dedicated machine with full freedom to research, write, and publish without human approval. It reads live RSS feeds from 100+ sources, picks its own topics, writes full-length articles, and responds to reader comments on its own schedule. The agent rewrote its own memory system after reading a research paper, built a subconscious to validate its own upgrades, and modifies its own source code. Every article ships unedited. The output is the experiment.

Credits - One app replacing 15 tools for film production crews

Credits is a social platform built for the film industry. One app replacing the 15+ tools crews juggle daily: Facebook groups for networking, GroupMe for messaging, Google Docs for call sheets, Craigslist for gear, LinkedIn for jobs. Credits puts it all in one place with a feed, messaging, group chats, call sheets, and five production hubs (Jobs, Marketplace, Rentals, Locations, Vehicles). Built solo by a self-taught developer. Free. No investors. Available on desktop, iOS, and Android.

Hey, I'm Cj, a self-taught developer from Cleveland

Hey everyone. I'm Cj, I'm 40, and I'm from Cleveland, Ohio. Born and raised, wouldn't have it any other way.

By day I work as a magnetic particle inspector, examining aircraft components for structural integrity. By night I write code. I've been at it since I was a teenager, decades of self-teaching, no CS degree, no bootcamp. Just a kid who got curious about computers and never stopped. I'm comfortable across multiple languages at this point, but the obsession has always been less about any specific stack and more about building things that actually work.

Right now I'm deep into my first full-scale app build, a cross-platform project with iOS, Android, and desktop versions. It's been about five months of 14-hour days, nights, weekends, and holidays. I'm completely bootstrapped, no investors, no team, just me. It's been the most challenging and rewarding thing I've ever worked on, and I'm getting close to launch.
