Things I’ve built for fun, for friends, or to learn something.

Production apps, experiments, and older work. Between them they cover most of what I touch: full-stack web, mobile, machine learning, and DevOps tooling.

Most repos are private. Each one below has either a live demo or a request access button that opens an email draft. Fill it in and I’ll grant read access when I can.

  • Squadra

    Full-stack web / 2026 / Production / private

    World Cup 2026 quiniela web app for friends.

    A real production app: a prediction-pool platform for a private group to compete during the 2026 FIFA World Cup. Auth, RLS, realtime, internationalization, the whole thing. Currently in active use.

    Source is private (production app for a closed group).

  • Astra DevOps

    DevOps tooling / 2025-2026 / Active development / private

    Opinionated Internal Developer Platform for production-grade AWS.

    An IDP that gives startups the deployment workflows and operational maturity of a mature platform team, without having to staff one. Infrastructure runs in the customer's own AWS account; Astra provides the control plane.

    Combines everything I do day-to-day at work into one packaged product: IaC, deploys, observability, security baselines.

  • Xtock

    Machine learning / 2025 / Active development / private

    ML model that predicts the stock market from X (Twitter) posts.

    Trains and serves a model that ingests posts from X and tries to predict short-term stock movement. Experimental sandbox for ML inference, fine-tuning, and MLOps patterns.

    Personal R&D project for exploring inference latency and model serving.

  • Stylistic

    Mobile / 2024 / Archived / private

    Cross-platform fashion app: mobile frontend with a Rails backend.

    React Native (Expo) mobile app backed by a Ruby on Rails + Postgres API. End-to-end CI/CD via CircleCI deploying the phone build and the backend to Render. Demonstrates mobile dev plus full-stack ownership.

  • Generational Pictures

    Frontend / 2023-2024 / Production

    Static brand site for a photography studio. Built before the AI boom.

    React + Tailwind static site I designed and coded with a collaborator for a photography brand. The first real frontend project I shipped end-to-end, and a useful proof point that the React and UI work predates the current AI tooling era.
