## About
I work where strong engineering meets thoughtful interaction design. From offline-first travel companions to sports analytics and healthcare dispatch, I turn complex constraints into clear, dependable mobile experiences.

### Build for the real world
Offline behavior, slow networks, background work, and edge cases are part of the product—not afterthoughts.

### Make complexity legible
Clean architecture and clear state models give teams the confidence to move quickly without creating fragile systems.

### Ship the useful thing
I partner closely with backend and design teams to focus engineering effort on outcomes people can feel.

## Projects
### GoScotland
Real-time travel companion · Offline-first synchronization
GoScotland is a real-time travel companion built for journeys that cannot depend on a perfect network. I led the mobile experience around offline-first journey synchronization, so planned trips, live vehicle data, and disruption alerts stay usable when connectivity drops.

Background geolocation, WebSockets, and local plus push notifications keep travelers informed without asking them to babysit the app. The product is designed for the messy middle of public transport: delayed services, patchy signal, and the need to keep moving.

### Sports Metrix
Athlete performance platform · Hardware + analytics
Sports Metrix turns training sessions for wheelchair athletes into useful, real-time performance insight. I directed the mobile product around custom hardware integration so session data from connected equipment becomes something coaches and athletes can actually act on.

The work sat at the intersection of IoT, Bluetooth Low Energy, and session management—capturing the session, making the analytics legible, and keeping the experience focused on performance rather than the hardware underneath it.

### Mios
Performance & nutrition · Precision interaction design
Mios is a companion for professional athletes to track caloric intake and exercise output. I supported a demanding custom UI system with charts, graphs, and integrations to Garmin and TrainingPeaks so the product could keep pace with how pro athletes already train.

The interaction design had to feel precise: dense data without becoming noisy, and a visual system strong enough for Maurten’s performance-nutrition brand.

### Villey
Family support marketplace · Marketplace + Dual-role architecture
Villey is a two-sided marketplace that connects busy Australian families with verified local helpers for childcare, home support, and life admin. I owned debugging, optimization, finalizing, and publishing the Flutter app—from job posting through live sessions and Stripe payments.

The architecture had to support dual roles in one product: families and helpers, each with their own flow, while keeping the marketplace reliable enough for real bookings and payments.

### Mama Pizza
Commerce & Operations · Multi-store Food ordering & delivery
Mama Pizza is a multi-region restaurant app operating across Germany, covering online ordering, delivery, and order tracking. I designed and maintained the Flutter product, including Google Maps for store and delivery context and PayPal for checkout.

The work was about making a multi-store food operation feel simple on the phone: pick a location, order, pay, and follow the delivery without the complexity of the backend leaking into the UI.

### Ecommerce Template
Shopping template · Catalog to checkout
I built this Flutter ecommerce template as a full shopping flow—from featured collections and product detail through bag, wishlist, and checkout. Payments sit on Apple Pay and card flows, with Firebase handling the cloud side so a store can ship without assembling the stack from scratch.

The work covered the surfaces people actually use: categories, orders, shipping, and account settings, in both light and dark modes, so the kit could be a starting point rather than a demo.

### Short Video Template
Creator video platform · Feed + creator tools
I engineered this Flutter short-video kit around the For You feed, discovery, comments, and a post composer with sounds and captions. Chat, profiles, and account settings sit beside the feed so a creator community has somewhere to go after the clip ends.

The product problem was the same as any short-form app: keep the feed fast and the capture flow short, then layer social mechanics without turning the kit into a toy.

### Finance Template
Personal finance · Markets in one kit
I built this finance app template so a team could stand up portfolios, watchlists, expense tracking, and news without starting from a blank canvas. Stock and crypto detail screens, linked accounts, and onboarding were part of the same system.

The UI had to make dense market data feel usable: home, transactions, search, and settings that could be re-skinned for a brokerage or a personal-finance brand.

### Chat Template
Realtime messaging · Realtime conversations
I built this Flutter chat kit as a production messaging surface: conversation lists, group threads, media messages, search, and account settings. Image and video in the thread, emoji, and the actions around a group were first-class—not afterthoughts.

Realtime communication only feels simple when the list, the thread, and the composer stay in sync. That was the engineering bar for the template.

### Dating Template
Dating boilerplate · Swipe to match
I built this dating app template around the swipe loop: home, left and right swipe, match, and the chat that follows. Distance radius, VIP upgrade, and profile photos were part of the same onboarding-to-match path.

Dark mode sits on the core screens so the kit could ship as a product, not a light-theme mock. The work was about making discovery, match, and message feel like one motion.

- Product page: https://dopebase.com/app-templates/flutter-dating-app-template-backend

### Video Chat Template
Audio & video calling · WebRTC calling
I engineered this video chat template around WebRTC calling—one-to-one video, audio, and the conversation list that sits next to it. Contacts, group chat, and account settings share the same product so calling is not a detached demo screen.

The hard part is keeping call UI and messaging honest: ringing, in-call, and the thread you return to after hang-up.

- Product page: https://dopebase.com/app-templates/flutter-video-chat-app

### Real Estate Template
Property listings · Listings + maps
I built this real-estate template as a property listing product: home feed, listing detail, maps, and the agent conversation that happens after a viewing request. Admin-side listing management was in scope so the kit could back a brokerage, not only a browse UI.

The screens had to make search, save, and enquire feel like one path—especially on listing detail, where photos, map, and contact compete for attention.

- Product page: https://dopebase.com/app-templates/real-estate-flutter-app

### Instagram Template
Photo social app · Feed, stories, filters
I built this Instagram-style Flutter clone around the home feed, explore, stories, and the capture flow with filters. Account creation, profile, and the composer sit in the same product so it can be a social photo app rather than a feed screenshot.

Realtime feeds and stories only work if posting and viewing share one data model. That was the architecture the template had to carry.

Tags: Flutter, Firebase, Stories, Social feed
- Product page: https://dopebase.com/app-templates/flutter-instagram-clone

### Dashboard Template
Data & operations · Ops on mobile
I built this dashboard template for teams that need charts, recent orders, and a management home on phone and tablet. Profile, feed, and the dashboard itself share one visual system so operations data does not feel bolted on.

The work was about making business metrics and lists readable in a mobile layout—dense enough to be useful, quiet enough to scan.

### Universal Listings Template
Marketplace starter · One kit, many verticals
I built this universal listings template so the same codebase could become classifieds, a directory, or a multi-vendor marketplace. Home, listing detail, and welcome onboarding share a listing model that can be re-skinned per vertical.

The product bet was versatility: one listing, vendor, and browse architecture instead of a one-off for each marketplace flavor.

- Product page: https://dopebase.com/app-templates/universal-listings-flutter-template

### Fitness Template
Wellness & training · Training + community
I built this fitness template around home, steps, nutrition intake, and the community surfaces that sit next to training. Fingerprint unlock and account flows were part of shipping a wellness product, not a workout list in isolation.

The kit had to hold tracking and social in one app—so a team could launch a fitness brand without splitting those into two codebases.

Tags: Flutter, Fitness, Nutrition, Social
- Product page: https://dopebase.com/app-templates/flutter-fitness-app-template

### Social Network Template
Social platform · Feeds and stories at scale
I engineered this social network template around feed, discover, stories, and posting. Account, profile, and sign-in sit in the same product so the kit is a social ecosystem rather than a feed widget.

Realtime stories and an advanced feed need a backend story that can scale. That was the infrastructure the Flutter client was built to talk to.

Tags: Flutter, Firebase, Stories, Social feed
- Product page: https://dopebase.com/app-templates/flutter-social-network-app

### Food Delivery Template
Multi-vendor delivery · Three-app delivery stack
I built this food delivery template as a three-sided product: customer home and menus, cart and checkout, orders, and the chat that happens during a delivery. Map tracking and payments sit in the same flow so the kit is an operation, not a restaurant list.

Dark variants on home, cuisines, orders, and profile were part of making the customer app feel finished across day and night use.

- Product page: https://dopebase.com/app-templates/food-delivery-flutter-app

### Login Screen Template
Auth starter · Auth, ready to drop in
I built this login starter so auth did not have to be reinvented on every app: welcome, sign-in, create account, profile photo, and permission modals. Error and uploading states were included because that is where auth actually fails.

It is a small surface, but it is the first one users hit. The work was making that path complete enough to drop into a larger product.

- Product page: https://dopebase.com/app-templates/flutter-login-screen

### Walkthrough Template
Onboarding kit · First-run intro
I built this walkthrough starter as a first-run intro sequence—four screens that can be re-skinned for any product’s onboarding. The point was a clean, reusable motion into the app rather than a one-off carousel.

Teams used it to skip the empty first-launch problem and start from a real intro, not a placeholder.
