I’m working on Ovio (https://ovio.au), a record-keeping app for Australian freelancers/sole traders/small businesses. The current version is deliberately narrow: send receipts by email/whatsapp; import bank transactions from CSV; and Ovio extracts the details and auto reconciles. From there you can check a BAS/GST-style summary and export organised records for an accountant.

It's been quite fun building this as this solves my exact problem, but trying to find an audience for a product is a completely different game

I got tired of Codex/Claude not being able to write good UI reliably, so I made a TypeScript library toolbox to help with that.

https://github.com/yuechen-li-dev/MachinaLayout.JS

Pretty much just SwiftUI-like layout/style in TypeScript with a bunch of utility tools from other languages I like, like Rust's payload enums, table helpers, LINQ-like queries, state management, etc. It's framework neutral so it works with React, React Native, and Vue right now. Everything is just plain TypeScript that compiles to the DOM, so no HTML or CSS needed for most normal web apps, they can all be written in plain .ts or tsx files.

I'm working on a side project to clean up and fix EPUB files with transcription errors, incomplete or inaccurate metadata, and other issues. Users can accept/reject/edit the fixes as they go through it. I have the command-line interface and TUI working (thanks to Ratatui), but I'm still working on a Calibre plugin and web-based version using WASM.

I'm exploring triply periodic but non-minimal surfaces. https://codeberg.org/okaleniuk/faitps

Triply periodic minimal surfaces are the golden standard in thermal management, acoustics, and even medical applications. But minimality itself doesn't contribute much to practicality. We use them because they are simply studied better than the non-minimal surfaces.

So I'm studying the non-minimals. They are much more governable, what I link to is a demo of a surface builder with two levels of control. Next, they are conjugatable including conjugations with different period of self (that will be the following paper), they generalize nicely to non-periodic or partially periodic surfaces, and they work in other space configurations. E. g. I'm now playing with bi-periodic curves that cover the 2D space with self-replicating hexagons.

If all that I'm experimenting on today in 2D will turn out well in 3D too, we'll have a whole new direction in implicit modeling.

I am working on a Jupyter notebook client for VisionOS. It allows for 3D data to be visualized on visionOS. Right now it supports point cloud data, USDZ models and Gaussian Splats. I am working on it to launch on the App Store. Sign up for more information at http://www.pulto.org

https://terminai.app

I got sick of choosing between the efficiency of working in a terminal and the magic powers of using AI (and of copy-pasting between the two). So I created a hybrid: Terminai is a transparent wrapper for any terminal that provides on-demand access to a TUI coding agent of your choice just a hotkey away (with built-in MCP and CLI that gives the AI access to your terminal).

Two side projects I’m actively working on: https://openaltfinder.com - To help people discover selfhost-able open source projects. Been maintaining this for almost a year, and it’s been fun. Keeps me up to date with new OSS. https://getpinnd.com - A small social network for map makers to created shared lists of places. Was just a spur of the moment, and ended up building it in little than a week.

Nice. I tried to submit a project on the former. However CloudFlare seems to be blocking me from submitting the form.

This is a common issue for all of us in Viet Nam though, not sure if there's anything you can do your side. I'll figure out how to get my submission through later :)

I’m still working on a price API for the Counter-Strike 2 market that provides real-time & historical data.

Since my last post in February, I’ve gotten to ~25 paying users, which is cool considering it started as a fun project. Sorta a niche within a niche here.

The market is distributed across a bunch of 3rd-party marketplaces, and there's no 'simple' API that provides genuinely high-quality data for the few marketplaces that matter. It’s a surprisingly complex problem, which is probably why nobody else is bothering :).

It's been a super fun project, and I've been able to learn about collecting & managing a high (to me) scale of data, building an API from the ground-up, and creating my first 'commercial' website.

Website is @ https://cs2.sh/

The API is built w/ Go & Clickhouse, which I've also been super impressed with so far in terms of performance and efficiency.

Web design is inspired/somewhat taken from turbopuffer's site, since I really liked it.
