Apps, APIs and the hardware they talk to.

An offline-first app that crews and safety staff at 30+ airlines use, in 19 languages, to file safety reports, run audits and read operational manuals, often with no connection.

Offline and sync

• Every report, risk assessment and audit is saved locally first in an encrypted database, so crews can work with no network.
• Each record moves through draft, pending, uploading and synced states, so people always see what is still on the device.
• Uploads run as background workers that resume after the app is killed. Manual sync runs in the foreground with a visible notification; automatic sync waits for Wi-Fi.
• Manuals sync by folder for offline reading in an in-house PDF viewer, with outdated revisions flagged.

Scale

• Each airline is set up from configuration (report forms, sign-in provider, branding), so a new client needs no app rewrite.
• Split the app into feature modules, with unit tests on the sync layer.

An AI agent that talks to conference attendees in WhatsApp and other chat apps, helps organizers run the event and captures leads for sponsors. A new product already in use at live conferences.

• Work on the conversational agent that answers attendees and organizers over WhatsApp, Telegram, email, Apple Messages and Slack: a tool-calling LLM loop on the pi agent harness, with a knowledge base to answer from and playbooks for multi-step flows.
• Built the knowledge-base review agent: it crawls an organizer's website, compares it with the event's knowledge base and proposes one set of changes for the organizer to review.
• Prototyped the onboarding, organizer and WhatsApp agents (tools, sessions, prompts, web search) that went into the product.
• Built LLM data pipelines for sales: conference discovery with structured extraction, a LinkedIn matcher and company enrichment.
• Work across the whole stack: messaging webhooks, database migrations, background jobs, API and the organizer app.

My own household app for keeping the home organized, in development and not yet released: bills, spending, shared shopping lists that sync live, calendar, meal planning, recipes, pantry, chores and loyalty cards. Native on iOS, a web app everywhere else.

• A native iOS app in SwiftUI, with the shared logic in its own Swift package, Shortcuts and Siri support through App Intents, and on-device scanning of payment-slip barcodes with Vision.
• The web app and API in SvelteKit, installable as a PWA, with live-syncing shopping lists, notifications and invite-only sign-in.
• Unit tests with Swift Testing and UI tests with XCUITest; self-hosted with Docker.

Camera-driven games, AR mirrors and kiosks for consumer brands at events and in stores. Visitors play with their body, and the app reacts in real time.

• Built 30+ Unity apps (Unity 6, URP) that run unattended on Linux kiosks and are configured remotely.
• Worked on the Rust core that Unity loads as a native library: camera input from webcams, RTSP streams and industrial cameras, and a lock-free worker pipeline that keeps frames flowing.
• Image processing in Rust, plus pose and face detection workers that turn camera frames into game input.
• Built an Android launcher for a dual-screen tabletop display that keeps both screens running through crashes and reboots.

A field tool, built in Kotlin Multiplatform for Android and iOS, that installers use to set up and maintain cellular IoT sensors on boats.

• Bluetooth discovery and connection for three device generations, with signal, battery, cellular status and firmware version.
• Configuration over Bluetooth: mobile network and APN, server endpoints, encryption keys, measurement intervals.
• Device maintenance: firmware updates through bootloader mode, time sync, factory reset and download of stored measurements.
