#12I'm working on a workflow automation tool that lets devs write workflows in simple yaml files, and then deploy them to the cloud _or_ on premise. Each workflow is a set of actions and a trigger that can transform data, make api calls, run AI models, or really anything (via docker!). Each step relies on the output of the last step, and the workflow framework is engineering to be declarative, testable, and versioned. Similar to GitHub actions, but for *anything*. Think webhook to slack, email to support ticket, nightly aws backup & restore, mirror a file each night, etc.

#13I've been working on mock:
https://dhuan.github.io/mock/
the process of creating APIs for testing and automation should be as easy possible. the tools that exist nowadays for this purpose aren't good enough IMHO, which led me to build it.

#15Still working on https://theretowhere.com since I announced it to HN in February.
It's an website who's goal is to make it easier to find apartments/hotels/etc that fit your housing preferences (starting with places that are close to the people and things you care about). It's flagship feature is the ability to make heatmaps of cities based on your preferences.
Since February I've slowed down on feature development temporarily as I try and find a way to sustainably increase it's popularity and learn what's the most important thing to focus on next.

#16A language learning app for couples (https://couplingcafe.com). I wanted to learn my wife's native language, so I've been building this on my own for a long time and testing solutions! Just a few paying happy users. Cooking up a lot of ideas

#17I’m working on extending Postgres to run on top of FoundationDB. The goal would be turning Postgres into a distributed, horizontally scalable database with automatic sharding and replication.
Hoping to share a first version of it soon. It’s been absolutely fascinating digging into Postgres internals!

#19I am working on the https://moviemovie.club/about, it's a tiny website about film review.
It works like a run club, where you have to make a review first to see other people's reviews.
I am currently implementing watchlists, comments and a mural to make it feel a bit less lonely. Right now I like the UI but it feels to lonely.
