Hello guys, as university student that wants to apply to junior Rails dev, i made project that even you can try.

It works as stock broker portfolio agregator (Trading212 and Etoro), that takes snapshots of current account balance, exchange it to live EUR rate, and sums them into nice looking chart.

Its all happening in background job so you dont need to worry about that.

Then it notifies you each day about the difference summary, or if your API keys are wrong.

i deployed it on my VPS with kamal (easier than i thought) so you can try that yourself (you can set your API keys to read-only, but i respect that prolly noone will put it there).

Also you can try that yourself as i already set it up with Docker for you.

I am open to any critism or ideas :)

I’ve been building FireFight, an open-source Slack-first incident management platform, on Rails 8.1 with Inertia + React.

I recently open-sourced it and started building in public, so I figured I’d share it here in case anyone is interested in looking through a larger Rails 8 app or following along.

Most of the incident workflow happens through Slack. Declaring an incident creates the incident channel, brings in the right people and keeps a timeline of what happened. There’s also an MCP/API layer that lets agents interact with the same system, with their own identity, permissions and approvals.

The next big thing I’m working on is the AI SRE side, with automated incident investigation and eventually resolution.

Happy to answer questions about how it’s built or why I made some of the choices I did.
