About TTCG

TTCG is a boutique technical studio. Joshua designs, builds and ships his own apps, and builds the same way for clients: one accountable builder, real code and working software instead of slide decks.

We take an idea from a sketch to a working product: the architecture, the interface, the deployment, and the unglamorous parts in between.

We work at three scales

  • App development

    We build the thing you've been describing to people for years. Web apps today. Android and iOS are coming, not available yet.

  • One-off services

    A scoped single project — a build, fix, integration or setup — quoted per job, that solves one problem cleanly.

  • Subscription services

    Ongoing monthly support or work, offered since May 2026, to keep a product running, maintained, and improving after launch.

Stack we actually use

  • Google AI Studio
  • Gemini API
  • React
  • GitHub
  • Stripe

The apps

Everything below was built in-house. These are our own products, made with the same tools and standards we bring to client work. svnt is live now; the other five are coming soon, and where a preview is already reachable, the card links to it.

  • Screenshot of the svnt harmonic analyzer: headline “Zero theory. 100% instinct.”, an audio or MIDI file upload, and playback controls.

    Live now

    svnt

    Load a song and see how it's built. svnt estimates the key and tempo, marks likely clashes, and answers with rules-based coaching rather than a language model. Your audio and MIDI stay in the browser tab, and no sign-in is required.

  • Screenshot of the Jacob's Ladder opening screen: a gold ladder emblem above the title and the line “Find your alignment” on a dark background.

    Coming soon

    Jacob's Ladder

    Find your alignment. An astrology and reflection platform with optional dream reflection, journaling, and AI guidance, plus The Return, a quest through twelve symbolic aspects. It's offered as symbol and invitation: beyond religion, beyond science, and always optional.

  • Screenshot of the Lumina ebook studio dashboard in guest mode: a welcome panel, an inspiration panel, and template cards such as Classic Regency and Cyberpunk Noir.

    Coming soon

    Lumina

    An ebook studio with an AI collaborator, for writers who want the book to look as considered as the words. Draft, design, and package the manuscript in one place, from first page to finished grimoire.

  • Screenshot of the Extrapolashia workspace in guest mode: a prompt input panel on the left and a strategic breakdown panel on the right.

    Coming soon

    Extrapolashia

    A prompt architect that listens. Describe what you need and Extrapolashia works it over with a set of sibling personas, tunes it for your target platform, and hands back the optimized prompt with a written breakdown, as Markdown, plain text, or PDF. You can speak your input, and signed-in users can save and reload prompt versions.

    ONYX

    A résumé workspace that turns your work history into ATS-oriented career documents, with cover letters, version snapshots, and multi-format export. It's a sharper tool, not a promise.

    Web only. ONYX does not guarantee interviews or jobs, and it does not apply on your behalf.

  • Coming soon

    Forge Studio

    In development — no public link yet

Screenshots of svnt, Jacob's Ladder, Lumina and Extrapolashia were captured from their public previews on Nov 10, 2026; previews are works in progress and may change. ONYX and Forge Studio show placeholders until they have a public preview.

Consulting

Bring us the problem, whether it's half-built, broken, or still in your head. We design and develop web apps (mobile is on the way), wire in AI where it actually helps, handle deployment and payments, and leave you with something you can run yourself. You can book a single fix or a full build, or keep us on with a subscription.

Games, coming soon

Not everything we build needs to be useful. Our games and interactive stories are in development: small worlds with their own rules, waiting for the lights to come on. Check back.
