Everything I have shipped

Ten things that are live right now. Four of them are mine, which means I am also the person reading the one-star reviews.

Client work proves I can deliver what someone else specified. My own apps prove something different: that I choose what to build, ship it, charge for it, and keep it alive afterwards. Every problem I warn you about on the first call is one I have had on one of these four.

CABA Test

Live · iOS and Android

A companion for the Buenos Aires driving-theory exam. All 459 official questions, translated into English and Russian, with the ability to switch language mid-question so you can check what a term actually means without losing your place. Progress statistics and a checklist for the paperwork side of getting a licence.

Why it is hereThree languages in one app, and the translation pipeline survives the city publishing an updated question set. Free with ads, one purchase removes them.

AimYear

Live · iOS and Android

A yearly goal tracker across five areas of life: health, finance, relationships, work and happiness. Up to fifteen aims, a daily check-in that takes one tap, and visualisations that show the year filling in. Paid tier adds cloud sync, web access and AI-written insights.

Why it is hereMy own money is in this one. Subscriptions, restoring purchases, refunds and one-star reviews are things I have handled on my own product before handling them on yours.

Focido

Live · iOS and Android

A social to-do app with real motivators. You create a feed of the things you intend to do and invite people as accountability partners, who can see the feed and nudge you. Built as a co-founder rather than a contractor.

Why it is hereCo-founded, which means I made the product decisions as well as building it, and lived with the ones that were wrong.

Derivografías

In testing · publishing soon

An app for artist Vivian Galbán's installation at the 2026 Buenos Aires International Architecture Biennial, at galería Rolf Art. It records each visitor's path through the space and how long they pause at each point, turning a walk into what the artist calls a cartography of pausing. Every participant's route is projected live in the gallery during the exhibition.

Why it is hereCurrently in testing with real visitors before the exhibition opens. Geolocation indoors, running for hours on visitors' own phones, feeding a live projection.

Built for clients

Work someone else paid for and now depends on. Two of these were published under the client's own developer account, which is normal and is also how yours would be.

Tools and platforms

Not phone apps. Things I built because I needed them and then kept running.
