My core stack is Swift, Rust, TypeScript and CSS, Astro and Sanity CMS for content-driven platforms and Cloudflare for infrastructure, storage and edge services. My work is rooted in integrity and transparency: technology that is useful, responsible and makes a meaningful contribution to people and the planet. If you're a founder with an ambitious idea and need someone to own it end to end, let's talk. Peace.

    Sequence: Brand, Web and App

    https://www.twine.net/signin

    Sequence is a native macOS workspace for transcribing, refining and preparing audio and video before the creative edit. It grew from scripts built to remove repetitive post-production work into a complete product spanning brand identity, native application, website, documentation and launch content.

    The product keeps media processing close to the machine, using on-device transcription and a non-destructive project model to help editors search recordings, refine spoken content, remove silence, prepare audio and carry editable decisions into finishing applications such as Final Cut Pro and DaVinci Resolve.

    Its identity is built around keyframes, layered variants and forward movement. That system extends from the app icon and interface to campaign imagery, product education and a public platform supporting downloads, accounts, documentation, releases and ongoing customer support.

    Talia Duvet - Canadian Music Artist

    Talia Duvet's Website
    Talia Duvet's Website Portal

    https://www.twine.net/signin

    Talia Duvet’s launch website refines the Canadian artist’s existing wordmark, star motif and playful handmade language into a flexible digital identity. Each track can introduce its own portraits, stickers, colours and supporting media while remaining part of one coherent world.

    The Astro website is paired with a tailored Sanity Studio, giving Talia control over tracks, streaming destinations, events, media and page visibility. Private previews and staging allow each release to be prepared visually before publication while the public experience remains fast and largely static.

    The project also establishes the technical foundation for a future fan portal, with authentication, protected environments and supporting services designed into the platform from the beginning.

    LeWalk - Posters

    Lewalk Bohemian Sweet Treat

    A pair of visual campaign experiments for LeWalk, translating its local-led Paris walking tours into bold poster concepts. The work combines editorial typography, travel ephemera and destination imagery to frame the app as a route into the city’s food, culture and hidden stories.

    CharGrid - iOS Sudoku game without dark patterns.

    Chargrid is a fast, offline-first native puzzle app for iPhone and iPad. Its first game is Sudoku, designed around immediate touch, keyboard and Apple Pencil input without advertising, interruptions or dark patterns.

    The SwiftUI interface is backed by a dedicated Rust engine that generates valid puzzles, checks solutions and stores progress locally through SQLite. Optional assistance, appearance controls, offline puzzle sharing, iCloud support and honest Game Center leaderboards create a polished experience that remains quiet and focused on play.

    The architecture establishes a reusable home for grid puzzles, keeping platform-native interaction separate from the rules and persistence engine so both can evolve cleanly.

    Genius Community - Intuitive Design and Evolution

    https://www.twine.net/signin

    Genius Community presented a unique opportunity to work with an alchemist coach seeking to create a brand experience that transcended conventional design approaches. The client required a complete brand ecosystem that would reflect their metaphysical practice while maintaining a professional, accessible presence. Our collaboration extended across multiple touch points including:

    • A bespoke website centred around sacred geometry
    • An intuitively developed brand mark
    • Custom business cards with cryptic design elements
    • Ongoing brand evolution strategy

    The idea was to create the brand as a living, evolving entity rather than static identities-a philosophy we bring to all our client partnerships.
