#2I'm working on Cali Challenge. A calisthenics workout app with a daily challenge that gradually increases in difficulty. It guides you through the different progression levels of core calisthenics moves like push-ups, pull-ups, and dips.

#3I'm working on a tool to convert any OpenAPI JSON spec to an MCP server, so LLMs can interact with it. If anyone's interested in this, email in my bio. I'll also put it on my Github soon, once I polish up the code.

#6Taking shader programs (they have a main() functions), hacking up their source code / AST to turn the into modularized code packages, and then enabling composition of shaders by injecting the output of one module into another (essentially calling the main function of one shader in another). This enables arbitrary shader composition. One application is Photoshop-style stacking of shaders as layers, like https://shaderfrog.com/2/editor/cm6y90vai002mpaxio3zjhfvq
Or getting real freaky with it by composing many effects deep https://shaderfrog.com/2/editor/cm1s7w23w000apar738s9d1x0

#7Been building an automated test builder and an agentic API generator for the past few months.
tl;dr: A 60fps embedded browser on the frontend lets you record manual steps and AI-driven steps (to assert/extract data). It then turns those into test suites. Any test with AI queries can auto-generate an API to be queried later.
Right now, I'm working on an agentic API builder. Example use case: Say you need data from Salesforce and JIRA — you log in, navigate to what you need, add an AI query step (or select elements manually), and set an update interval. The system then handles extraction and monitoring.
Why? Because at all my previous jobs, suggesting hiring QA engineers would get you laughed out of the room. But testing was desperately needed, as well as internal tooling. Burning developer/CTO time on wrangling multiple complex API's just to build some internal tool would take much longer without this. So I'm working on something that makes both vastly simpler for small teams. Hoping to have a workable demo next week!

#8I'm working on my web framework Mayu. Haven't had much time lately but I found some time to make a few improvements.

#10To aid my process to shortlist house for purchase I am creating a web app for this.
The app will use genai to extract the details of houses listed for sale and then update my custom database.
For example I can input a youtube url and it will fetch the transcript and use llm to generate Json response based on predefined schema.
I can review and shortlist the houses based on various custom parameters using the web interface.
The mvp is done in a proprietary tech stack, I just need to port it to open source tech stack with React and FastAPI
