Six years of Android.
Now, at the speed of agents.

I own the judgement.

I’m Ángela, an Android developer. Kotlin and Jetpack Compose on client teams since 2020.

I also work with AI agents like Claude Code: I write the specs and review the work; they implement it. In my spare time, out of curiosity, that’s how I explore other platforms such as web and iOS.

01 · What I bring

Real experience. Agent speed.

My day to day

Android development

Six years building apps for clients have given me what an agent doesn’t have: judgement. I can recognise good architecture, spot technical debt and tell when a change isn’t ready.

How I work

Building with agents

Outside work, I also build my own products with agents. Product direction is mine: what gets built, for whom and why. They implement; I bring the spec, the context, the review and the QA.

    Android Developer · Remote Habitissimo

    An Android team of two, with lots of autonomy and real ownership of every feature, from idea to production.

    100% Kotlin · Small team · End-to-end ownership

  3. Alten

    Mar 2020 — May 2022 · 2 years and 2 months

    Android Developer · Remote · My first role Inditex

    I owned the Uterqüe Android app until the brand closed, then moved on to other apps in the group.

  4. AskUs

    2020 · Final diploma project

    Where it started: my first complete app, end to end.

    A Q&A social network with posts, comments, voting, community moderation, achievements and dark mode. I built the Android app, the REST API and the database.

04 · Let’s talk

Shall we talk?

Always up for a good conversation

I love hearing other points of view and learning how other people work. Write to me if…

  • you’ve played Puntokus and want to tell me something (good or bad).
  • you liked something about this site.
  • you just want to say hi.
