Working on https://practicecallai.com/ - simple saas that lets users run practice calls / role play against a custom AI partner. Goal is to make it the easiest to use & fastest to get started with in the market.

It’s been a fun, practical way to continuously evaluate the latest models two ways - via coding assistance & swapping between models to power the conversational AI voice partner. I’ve been trying to add one big new feature each time the model generation updates.

The next thing I want to add is a self improving feedback loop where it uses user ratings of the calls & evaluations to refine the prompts that generate them.

Plus it has a few real customers which is sweet!

I'm working on a DnD character sheet app! I spent last week implementing the core DnD SRD ruleset, but what I'm really excited about is ML integration. I want to add a self-hosted fine-tuned ML model that acts as a character and DM assistant. Obviously an LLM via API can do the job, but I'm really curious if it's possible to build smaller, cheaper, task-specific models. Plus, I've never integrated an ML model into a product before, and I'm curious to play with it. I'm thinking of it like clippy for DnD: "it looks like you're trying to cast fireball?"

Besides the LLM experimentation, this project has allowed me to dive into interesting new tech stacks. I'm working in Hono on Bun, writing server-side components in JSX and then updating the UI via htmx. I'm really happy with how it's coming together so far!

I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts; I released a new version last month (and posted it on the September thread) and just merged automatic volume data migration the other day. Next goal is to design a system for downloading and loading remote components, similar to ansible roles. Hopefully I can tie it into the new podman quadlet install/etc commands.

Building a tool that automatically generates living infrastructure diagrams from your IaC files and turns them into real-time incident dashboards. Think Figma meets Datadog - beautiful visualization that updates during outages to show you exactly what's failing and how to fix it. The insight: your architecture diagram shouldn't be a stale PNG in Confluence. It should be your war room during incidents. Going to be ava…

Mind sharing a link? That sounds really interesting!

That sounds amazing. Which IaC tools are you starting with? Do you pull metrics and logs from the AWS/GCP APIs?

Thank you. Yes, it integrates with your own AWS/GCP accounts. As for the IaC, targeting the most obvious ones - CFN and TerraForm.

I'm working on Debtmap - An open source Rust-based code complexity analyzer that tells you exactly which code to refactor and which code to test for maximum impact. Combines complexity metrics with test coverage data to identify the riskiest code in your codebase. Uses entropy analysis to reduce false positives by distinguishing genuinely complex code from repetitive patterns.

Hmm, a personal assistant of sorts that does evaluation of you to get to the bottom of who you really are. For very obvious reasons, it is a local only project and not exactly intended for consumption.

Beyond that, just regular random stuff that comes up here and there, but, for once, my hdd with sidelined projects is slowly being worked through.

Currently a one-man side project: https://laboratory.love Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard. That seemed solvable. Laboratory.love lets you crowdfund independent lab testing of the specific p…

It's sad that it's come to this on needing to test these things, but amazing initiative! Would love something like this where I am.

Where are you? This project is not necessarily limited to products that are available in the United States. Anything that can be shipped to the United States is still testable.

I’m working on Leggen (https://github.com/elisiariocouto/leggen), a self hosted personal banking account management system. It started out as a CLI that syncs your bank account transactions and balances, saves them in a sqlite database and can alert you via Telegram or Discord if a transaction matches a filter. Recently I started refactoring the project with the help of Claude Code and Copilot Agent to include an API and a Web app to explore the data and configure it. The product is using GoCardless Bank Accout Data APIs to connect to banks via PSD2 but I found out recently that registering a new account is no longer possible so I’m currently looking into alternatives.
