I’ve built a background daemon that connects to Linear for one of my enterprise clients (multi-billion company). It runs autonomous AI workflows: – Creates PRDs from tickets – Waits for human review – Implements, verifies, and opens PRs automatically Built with LangGraph for orchestration, Codex + Claude for deep code understanding, direct LLM's API calls (via OpenRouter) for more deterministic tasks. It’s pretty cool watching the whole flow execute live in the console ⚡️

Introducing my new OSS framework: OhSnap provides really simple way to record and reproduce the data your users saw when encountering an issue (bug/crash), integration in your project should take a few minutes at most. Majority of bugs are related to data you have to deal with and often times we have to work with frequently changing data via network API's. Even if you have access to multiple environments (prod/staging/dev) it's still going to be PITA to reproduce a lot of bugs your user saw, since we often get to them a long time after the bug occured... OhSnap allows you to easily record any data your app downloads, pack it and put it on server so that you can replay it on your device later on, while connected to debugger and save hours of development time trying to figure out what exactly they experienced! Here's a demo of 2 app instances running, and me manipulating what server reply I'll be getting, there is 1 line of code needed to record and reply this data (outside of just setting up your framework). I built this so that I can show dev tool building process for the members of which I encourage you to join if you want to put your engineering efficiency at a different level😉

How much is your time worth? What if I told you that you could save hours of development time every week! Swifty Stack is my video course that will help you improve your engineering efficiency through best techniques, frameworks and tools. Launch sale Engineers can charge a lot per hour, applying this course recommendations will help you save many hours every week! You can use that efficiency improvement to either raise your rates, or spend the extra time with your family and doing things you enjoy outside of work. Remember that you can always make more money, but you can never pay money to recover the time you lost. Let me know what you think and I appreciate your support and sharing this with other devs.

has crossed over 100,000 USD in revenue! Honestly, I've not have expected this level of sales or positive feedback I've gotten for my first ever video course, thank you all for the support!🙇‍♂️🙇‍♂️🙇‍♂️ I've just added another chapter in which I talk about how I approach creating dev tools and frameworks and explain that you don't really need crazy engineering skills to make life easier for other engineers! #buildinpublic
