Hello, I am new and this is my first post.

At Sylvester I stopped smoking.for the beginning and hard times I searched for a deflection and started with my own quitesmoke app - purio

I released it some days before a reached a workable state.

Here the result, if you want to check:

I am working on a query cost analyzer that looks at query performance and does maths against your infrastructure cost to understand what is your dollar cost per query. The idea is that teams (when tables are tagged appropriately) will be notified with their most costly queries and hopefully makes that actionable for teams to clean up some queries.

I am unsure if there is a need for a tool like this in the market but I am becoming more and more curious around databases so this felt like a lower barrier for my product-minded engineer skills to get into.

I updated a really outdated, but surprisingly popular repo for linear programming:

https://github.com/JWally/jsLPSolver

I'm tinkering around building "JARVIS" (I didn't want to come up with a clever self deprecating name - this works) - a personal project to manage my life. Integrates into Google Mail, Google Calendar, Trello, GroupMe, EveryDollar. Basically it nags me to do grown up thing and is a better UX than Google Calendar/Trello - I just talk to it and ask it things.

Also experimenting with a new Claude-Code flow; give the bot its own AWS account, Put a bunch of tickets on my personal JIRA, be persnickity about what constitutes "pass" and tell the bot "follow these instructions, pull down tickets until there are no more. Your branch cannot merge until you have integration tests passing in your own dev env first" (I use AWS CDK). Then let it loose to build. The instant feedback loop that Claude has with Build-Code->Deploy to AWS->Run Integration Tests->Address Failures is really nifty fwiw...

I’m building AgentOS [1], trying to experiment where agent substrates/sandboxes will head next. It's a deterministic, event-sourced runtime where an “agent world” is replayable from its log, heavy logic runs in sandboxed WASM modules, and every real-world side effect (HTTP, LLM calls, code compilations, etc.) is explicitly capability-gated and recorded as signed receipts. It ensures that upgrades and automations are…

Ha. Nice name. Looks like we both are: https://github.com/saadnvd1/agent-os

I've been working on the same tool since 2024 where I thought it might be a good time to build a tool for all the people who will build their own tools, eventually they will need to market it.

So I built a SEO/GEO Automation Tool for Small to Mid-Size Businesses who don't have a full-time team for that. [0]

The goal is to provide teams visibility across all the channels — Search and AI and give them the tools needed to outrank their competition. So far so good, the fully bootstrapped venture has grown over the last year and I've built quite a few big features — sophisticated audit system, AI Responses Monitoring, Crawler Analytics, Competitors Monitoring etc.
