Ask HN: What Are You Working On? (December 2025)

I'm working on an affordable SaaS platform for small and mid-sized fabrication shops across the US and Canada. It automates quoting and production for sheet-metal and CNC jobs and can handle pretty much any CAD format, even full assemblies. On the AI side, we've got a mix of models doing the heavy lifting: a tuned geometric transformer for feature detection, a graph neural net for topology, and a vision model for mesh segmentation. All that ties into our custom CAD logic for geometry parsing, 2D nesting for laser/machining, and 3D nesting for forming and packaging. The whole idea is to level the playing field so smaller local shops can compete with the big instant-quote guys without needing an in-house dev team.

Feels like I'm working on a million things (between work, side contracts, and creative explorations). Recently a friend asked whether AI is helping or hurting my workflow.

And I realized I couldn't give a concrete answer. Lots of speculation, but I realized I didn't have hardly any real data. Inspired by Adam Grant's work on "rethinking", I'm _currently_ writing a tiny CLI to run self-experiments on my own productivity, auto-checking in / observing commits/code changes.

Goal at the end is to be able to test myself across different dimensions with "no AI", "moderate AI" (e.g. searching, inline assist), and "full AI" (agents, etc). https://github.com/wellwright-labs/pulse

Still working on the Mint programming language (https://mint-lang.com/) with a 1.0 release in January :). I'm happy with the current feature set, so I'm just polishing and optimizing where I can and giving the documentation a throughout look.

Planning on wrapping up the year with a year in review post (thankfully I've been writing monthly updates as I go, should save some time).

Apart from that, clearing up tech debt that helped me ship fast, but was ultimately a bad fit for the business (Next.js and GraphQL).

I've been working on a weightlifting logging app for the apple watch. I haven't submitted it yet since I am still beta testing, but I'm mostly feature complete.

It's intended to be anti-memetic, and anti-guilt trip. Just put it on your watch, install a program (open format) and you never need the phone itself. Your workout is a holiday from your phone.

The data can be exported if you want to use it elsewhere.

I originally made it for ROCKNIX but as there was no way to share the app I paid the Apple tax :/
