Makes software.
Occasionally
by the fire.

Tony Jara is a software developer based in Paraguay who once mixed sound at festivals and now ships products for people going out, food businesses, creators and shops, with tools he builds for himself along the way. This is his portfolio, his notebook, and where he has fun.

Selected works

Four live products, built and run by one person. A fifth is taking shape.

Pasapy

Everything that's on in Paraguay

One calendar for concerts, theatre, exhibitions, parties and fairs across Paraguay, in Spanish and English, with a search that understands plain questions like “something free this weekend”.

A page for every venue, a form for organisers to publish their own events, and a weekly newsletter with a hand-picked selection of what's worth leaving the house for.

Fastermenu

Storefronts for food that moves

One link that tells customers what's cooking. Fastermenu replaces the bio link for food trucks, pop-ups, supper clubs, bakeries and market vendors, the businesses that sell by date and location rather than from a fixed address.

A weekly schedule with maps, a digital menu built from a photo, orders over WhatsApp with no commission, loyalty punch cards that live in Apple and Google Wallet, and a subscriber list for the next drop.

Subignite

Monetization for creators who own their space

Sell digital products, gate communities and get paid, all from a branded subdomain instead of somebody else's platform. Built for course creators, podcasters, community builders and developers who would rather not become engineers to charge for their work.

Audio, video, files, private links and community access, priced one-time or as subscriptions with trials. Telegram, Discord, WhatsApp and GitHub access managed automatically. Payouts through Stripe Connect.

Jajotopa

Mystery shopping, recorded and read

How does a shop treat its customers when nobody from head office is watching? Jajotopa sends anonymous shoppers to find out, for businesses across Paraguay.

Shoppers record each visit in a mobile app, with audio, photos and GPS. The recording is transcribed and analysed against what the business cares about, and the business gets a clear report with a score, strengths and what to fix.

Untitled

On the drawing board

Something is being sketched. It will appear here in the next issue, probably late, probably after a few more evenings by the fire.

Tools

Built for one user first, the author. Shared once they were good enough.

Half the job is the work. The other half is building the bench to do it on.

Tony builds his own tools. Not as a hobby on the side: it is how the work gets done. When part of the day is slow, fiddly, or done by hand for the third time, he stops and writes the thing that does it, then goes back to the job with a better bench.

Some stay small. These two grew far enough to share. They run on his machine from morning to night, the products above are worked on inside them, and they are free for anyone who works the same way.

kururu

One window for every coding agent

Runs Claude Code and Codex in terminals it owns, across every project at once. Tile them, hand them cards from a board, and talk to one session that keeps an eye on the rest, from the desk, the phone or Telegram. Close the window and they keep working.

It also renders what a terminal cannot: markdown, images, diagrams, and the app being built, proxied so it opens on the phone too. Kururu is Guaraní for frog.

Tile Bandit

Workspaces without the slide

A keyboard-driven workspace switcher that lives in the macOS menu bar. A workspace is a group of apps: one keystroke shows them, hides the rest and focuses where you left off. Windows never move, and nothing animates.

It knows which screens are plugged in and keeps workspaces and grids for each setup, and it does the keyboard's half of the job too: remaps, dual-role keys and chords, per keyboard. Swift, no dependencies.

The author

A short biography, in the third person, as tradition demands.

“If I had to choose, I would do it all again.”

— T.J., on career changes

Tony is a software developer from Paraguay. He started coding at the end of 2019, when a stretch of free time collided with an idea he had been carrying around for years. Good mentors did the rest. Today he designs and builds web products end to end, and works remotely with clients anywhere.

Before that he lived in the music world. He owned a rental company and worked as a freelance audio engineer at some of the biggest festivals in the region. The two careers overlap more than you would think: both are about working with people and figuring out what they actually need. Both involve an unreasonable number of cables.

Off hours he goes birding. He also uses Neovim, and would like you to know that.
